    目の水平方向の最大可動範囲は平均45°である．しかし目が限界まで動くことはほとんどなく，視線は基本的に視線と頭部方向がなす角度（視線角度）25°以内に分布している．我々はこの25°-45°の領域を“Kuiper Belt”と名付けた．当領域はユーザが意図的に目を動かさない限り視線が移動することはほとんどない．ゆえにKuiper Beltを活用することで，VRにおける視覚探索時の意図しない選択操作であるMidas Touchが減少すると考えられる．本稿ではKuiper Beltで視線インタラクションを行うためのパラメータ設計を行う実験と，Kuiper Beltを用いた手法の有用性と負担を検討する実験を行った．実験結果より，Kuiper Beltを活用することで視覚探索時の選択操作の高速化と誤入力の減少が可能であることが示された． The maximum physical range of horizontal human eye movement is approximately 45°. However, in a natural gaze shift, the difference in the direction of the gaze relative to the frontal direction of the head rarely exceeds 25°. We name this region of 25°-45° the “Kuiper Belt” in the eye-gaze interaction. We try to utilize this region to solve the Midas touch problem to enable a search task while reducing false input in the Virtual Reality environment. In this work, we conduct two studies to figure out the design principle of how we place menu items in the Kuiper Belt as an “out-of-natural angle” region of the eye-gaze movement and determine the effectiveness and workload of the Kuiper Belt-based method. The results indicate that the Kuiper Belt-based method facilitated the visual search task while reducing false input. Finally, we present example applications utilizing the findings of these studies.

    ストリームライブ配信の普及にともない，ライブ配信時の配信者と視聴者の交流手法が研究されている．配信者側の交流支援手法はさかんに研究が行われてきている一方で，視聴者側のデザイン検討は少なく，特にストリームライブ配信視聴中のテキスト入力手法は十分に検討されていない．そこで我々は，視聴者側のユーザ体験を向上させるライブチャット用キーボードの検討を行った．まず，我々はストリームライブ配信を日常的に視聴するユーザにインタビュー調査を行い，ライブ配信視聴者の習慣や問題点を調査した．その結果，ユーザはスマートフォンでストリームライブ配信を視聴することが多く，その際には横持ちスマートフォンでの視聴が好まれる傾向がみられた．同時に，既存のスマートフォン上のキーボードは動画画面と大きく干渉するため，視聴者の没入感とコメント意欲を妨げていることが明らかになった．そこで，動画を隠さず，ライブチャット交流を円滑にする横持ちでのスマートフォンに最適化したキーボードの実現を目指して1) 両手を負担なく活用できるダブルフリックキーボード，2) 動画背景に対する半透明キーボードを提案し，その有用性をユーザビリティの観点から検証した．結果，スマートフォンの横持ち操作において，両手保持を想定したキー配置は有効であること，および一定以下の不透明なキーボードは動画背景で入力性能が低下することが明らかになった．最後に，横持ちスマートフォンでの文字キー配置や動画背景での不透明度の影響について考察を行う． With the spread of live streaming services, interaction methods between streamers and viewers during live streaming have been studied. While there has been much research on interaction methods for the streamer side, there has been little design study on the viewer side, and in particular, text input methods during live streaming have not been sufficiently studied. We propose a keyboard for live chat that improves the user experience on the viewer side. First, we conducted an interview survey of viewers who watch live streaming on a daily basis to investigate their preferences and problems. As a result, we found that viewers often watch live streaming on their smartphones, and that they tend to hold their smartphones horizontally when watching live streaming. At the same time, it was found that the current keyboard on smartphones interferes significantly with the video screen, which disturbs the viewer's immersion in the video and motivation to comment on the content. Therefore, we propose a keyboard optimized for smartphones in landscape mode that facilitates live chat interaction. Key features of our keyboard are 1) a double-flick keyboard that can utilize both hands, and 2) a semi-transparent, less occlude video screen. We conducted a study to understand the usability of the proposed keyboard. As a result, we found that a key arrangement of the double-flick keyboard for two-handed interaction is effective in text input for landscape mode, however, high clarity of the keyboard decreases performance in text input while watching a video. Finally, we discuss the effects of key arrangement in landscape mode and keyboard opacity for a live chat on streaming video.

    In this study, we propose a one-handed target selection method, in which the selection is completed with only one tap and a small amount of movement of the thumb. In this method, in order to explicitly show the selection target, targets are rearranged in a semicircular shape around the finger so that all the selection candidates are not covered by the finger. In this study, as a method of selecting a rearranged target, we implemented and evaluated three selection gestures. One Half-Pie that directly selects the target by tilting the finger in the direction of the target, Two Half-Pie that selects the target arranged in two steps while switching by pushing the display, and RailDragger that selects the target according to the amount dragged from the tapped point. In the experiment, the pointing task was performed using each of the three selection methods, and the selection methods were evaluated from the viewpoint of the time to selection completion and selection accuracy. As a result, we found that RailDragger was the best for the selection time and Two Half-Pie was the best for the selection accuracy in the three proposed methods.

    In this paper, we present a method of applying a bubble lens technique, which is the method to achieve easy and fast selection for a small target, to the eye-gaze interface. This method makes it easy to select a small target in eye-gaze interface by activating magnification lens near the target to use knowledge that a saccade includes a ballistic movement and corrective movements. We performed a pointing task to validate usefulness of bubble gaze lens by comparing a bubble gaze cursor and a bubble gaze lens which is our proposed technique. Results indicated that our proposed technique always faster than the bubble gaze cursor, and reduced the error rate by 54.0%. In addition, the usability score and mental work load score was also significantly better than the bubble gaze cursor.

    We present a gesture input method using a ski pole as an input device, focusing on skiing as an outdoor activity. First, we designed a user-defined gesture by asking several experienced skiers to devise a gesture suitable for mobile device operation. To recognize the designed gestures, we implemented a gesture recognizer with a convolutional neural network (CNN) that uses acceleration and gyroscopic sensors under the grip of the pole. As a result of collecting data during gesture execution and conducting discrimination experiments, the correct answer rate was about 96.5% when learning with randomly selected data, and the average correct answer rate was about 85.8% when learning with one user's data as test data and another user's data. To confirm the false recognition rate during actual skiing, we collected data at the ski resort and discriminated it from the gesture data, and found that the recognition rate was about 99.3% during skiing and gesture input.

    There are a variety of sizes and thicknesses of holds used in climbing, and the ease of holding them varies greatly. However, the difficulty of holding has not been considered in previous studies on route exploration. In this study, we improved the search algorithm A∗ used in previous studies and incorporated the difficulty of the hold into the fitness. We also used the improved A∗ as the evaluation function to estimate the difficulty of holds using a genetic algorithm (GA). There was also no discussion on how many divisions of the hold should be divided by difficulty, so we assumed four divisions: 2, 4, 8, and 16 divisions. After adjusting the parameters during interviews with expert climbers, we compared the algorithm of the four divisions with that of previous studies using a questionnaire online. The results showed that the route of the algorithm, which considers the difficulty of the hold, was rated higher by expert climbers and that the 8-division algorithm was the best among the proposed methods.

    The aerial image projection methods using a semi-transparent screen or a half mirror are widely used in the entertainment field. In these conventional method, large scale devices are required for the display area of the aerial image and it is difficult to produce a widely movement of the subject. In this paper, we propose a movable double-sided transmission type multi-layered aerial image display technology for the purpose of achieve the movement of the aerial image out of the stage and to the audience seats. This technology is a simple optical system combining 4 displays and 4 half mirrors. The observer can observe both sides of the object as aerial images from two directions, front and back of the device, and can also observe two layers of near and far background aerial images from both sides by transmission and reflection with a half mirror. Since the order relationship between the depths of the near view and the distant view does not depend on the viewing directions of the front and back faces, multiple people can simultaneously view multi-layered, highly realistic aerial images from both sides of the device. The two background layers are shared for the double-side viewing direction by multiple harf-mirror structure. Although the proposed method has only four display surfaces, there are total of six aerial image layers, three from each side. We report widely from optical configuration of the proposed method, prototype implementation and application of actual events.

    Selecting a small target with an eye-gaze interface is difficult. Redesigning interface and/or increasing operation time are required for making eye-gaze interface easy to use. In this paper, we present a method of using an idea of bubble cursor, which is a kind of area cursor, for the eye-gaze interface in order to make it easy to select a small target while maintaining operation time and generality of interface design. We performed an experiment to validate our concept by comparing three interfaces, standard bubble cursor technique with a mouse, a standard eye-gaze interface with a point cursor, and the bubble cursor as an area cursor with eye-gaze interface in order to understand how the bubble cursor contributes to eye-gaze input interface. Results indicated that the bubble cursor with the eye-gaze interface always faster than the standard point cursor-based eye-gaze interface, and the usability score was also significantly higher than the standard eye-gaze interface. From those results, the bubble gaze cursor technique is an effective method to make eye-gaze pointing easier and faster.

    We present new alternative interfaces for zooming out on a mobile device: Bounce Back and Force Zoom. These interfaces are designed to be used with a single hand. They use a pressure-sensitive multitouch technology in which the pressure itself is used to zoom. Bounce Back senses the intensity of pressure while the user is pressing down on the display. When the user releases his or her finger, the view is bounced back to zoom out. Force Zoom also senses the intensity of pressure, and the zoom level is associated with this intensity. When the user presses down on the display, the view is scaled back according to the intensity of the pressure. We conducted a user study to investigate the efficiency and usability of our interfaces by comparing with previous pressure-sensitive zooming interface and Google Maps zooming interface as a baseline.

    We present a target selection method for smartwatches, which employs a combination of a tilt operation and electromyography (EMG). First, a user tilts his/her arm to indicate the direction of cursor movement on the smartwatch; then s/he applies forces on the arm. EMG senses the force and moves the cursor to the direction where the user is tilting his/her arm to manipulate the cursor. In this way, the user can simply manipulate the cursor on the smartwatch with minimal effort, by tilting the arm and applying force to it. We conducted an experiment to investigate its performance and to understand its usability. Results showed that participants selected small targets with an accuracy greater than 93.89%. In addition, performance significantly improved compared to previous tilting operation methods. Likewise, its accuracy was stable as targets became smaller, indicating that the method is unaffected by the "fat finger problem".

    Background Many studies indicate that companion robots are effective for supporting the health of older people have been reported however, there is little knowledge on supporting older people through conversation. It is thus necessary to explore the conversation style of robots to promote the psychological health of older people. Research aim The aim of this study was to explore which style of robot's utterance was effective for promoting relationship with older people: provide useful information or only ask questions and provide neutral responses. Methods We conducted a comparative study using two talking robots with the aim of promoting psychological health. One robot has programmed to converse frequently with people, giving them general advices the other robot was programmed listen frequently to people. Twenty-nine participants (average 70.28 years old) were randomly divided into two groups, and after having a semi-structured conversation with the robot, they responded to an impressive evaluation and interview. Results The results showed that there was a significant difference between the two groups the number of utterances of participants in the listening-robot group was significantly higher than that of the speaking-robot group. We analyzed the conversation content, and the results showed that participants had a more positive feeling toward the listening robot than toward the speaking robot. Conclusion We argue that social robots for older people should listen more than speak in order to promote a better relationship.

    A unique space called social space is formed in human groups. This space is strongly formed when people belonging to the group are actively communicating and will influence the behavior of a third party not belonging to the group. Moreover, overlapping speech occurs unconsciously in human everyday conversations, expressing entrainment, interest, understanding, and so on to the other party as well as becoming an important factor for producing active conversation. On the other hand, in recent years, humanoid robots have been put into practical use and demonstration experiments are actively being carried out. When assuming a future environment in which humans coexist with multiple robots, it is necessary to consider the space formed in a group of robots, but such research has not been conducted sufficiently. In this research, we implemented active communication between robots by overlapping their speech and investigated how humans perceived the space whitch emerged from it. As a result, it was indicated that overlapping speech improved the impression of conversation activity and that the space whitch emerged in the group of robots affected the behavior of the person observing the conversation.

    We present a composition support system that shows candidates of next melodies following user created music and melody. Non-expert of music composition, like beginners, have difficulties to create melodies in music. It would be effective if a system could support music composition. We develop an algorithm to generate candidate melodies following user's input, especially music and melodies. The algorithm was inspired by the idea of predictive text input interface. We actually generated and confirmed the candidate melodies by the proposed method, we found that it has room for improvement. Based on this result, we also tried to improve the proposed method and tried to improve the quality of candidate melodies. We then created a system for showing candidate in music composition interface to support writing music activities. We conduct evaluation studies to investigate the effectiveness of the proposed method and improvement. In the 1st evaluation study, we compared three condition melody generation methods and two condition dictionaries. From results, we confirmed that the effectiveness of the proposed method using combining Markov process and pattern matching and two dictionaries. In the 2nd evaluation study, we compared melodies in pre- and post-improvement. As a result, the score of music generated in post-improvement system, was improved and we confirmed that the effectiveness of the improvement.

    The objective of the present research is to observe to what extent the stereoscopic effect presents a solution for enhancement of user interactions in the Web context. This paper describes an experiment conducted to detect differences in perception between 2D and 3D graphical user interfaces of an e-Commerce web application. The results of the conducted user study among 39 participants indicate significantly higher performance of the 2D interface in terms of efficiency, satisfaction, and, consequently, overall usability. Therefore, for the studied sample, the stereoscopic effect had mostly negative impact on user interactions.

    Pets have been humans' best friends since ancient times. People have been living with pets since then, and relationships between people and their pets, understood as family members at home, have been well researched. Social robots have recently entered family lives, and a new research field is emerging that examines triadic relationships between people, pets, and social robots. An exploratory field experiment was conducted to investigate how a social robot affects human-animal relationships within the home. In this experiment, a small humanoid robot, NAO, was introduced into the homes of 10 families, and 22 participants (with 12 pets: 4 dogs and 8 cats), called "owners" hereafter, were asked to interact with the humanoid robot. The robot was operated under two conditions: speaking positively to the pets and speaking negatively to the pets. The contents of the utterances from robot to pet, which comprised about 30 seconds of about 2 minutes of dialogue, were different under the two conditions. The results of this study indicated that changing the attitude of NAO toward the pets affected the owners' impressions of the robot.

    Parameter tweaking is a common task in various design scenarios. For example, in color enhancement of photographs, designers tweak multiple parameters such as "brightness" and "contrast" to obtain the best visual impression. Adjusting one parameter is easy; however, if there are multiple correlated parameters, the task becomes much more complex, requiring many trials and a large cognitive load. To address this problem, we present a novel extension of Bayesian optimization techniques, where the system decomposes the entire parameter tweaking task into a sequence of one-dimensional line search queries that are easy for human to perform by manipulating a single slider. In addition, we present a novel concept called crowd-powered visual design optimizer, which queries crowd workers, and provide a working implementation of this concept. Our single-slider manipulation microtask design for crowdsourcing accelerates the convergence of the optimization relative to existing comparison-based microtask designs. We applied our framework to two different design domains: photo color enhancement and material BRDF design, and thereby showed its applicability to various design domains.

    Experimentation plays an essential role in exploratory programming, and programmers apply version control operations when switching the part of the source code back to the past state during experimentation. However, these operations, which we refer to as micro-versioning, are not well supported in current programming environments. We first examined previous studies to clarify the requirements for a micro-versioning tool. We then developed a micro-versioning tool that displays visual cues representing possible micro-versioning operations in a textual code editor. Our tool includes a history model that generates meaningful candidates by combining a regional undo model and tree-structured undo model. The history model uses code executions as a delimiter to segment text edit operations into meaning groups. A user study involving programmers indicated that our tool satisfies the above-mentioned requirements and that it is useful for exploratory programming. Copyright is held by the owner/author(s).

    Self-driving technologies have been increasingly developed and tested in recent years (e.g., Volvo's and Google's self-driving cars). However, only a limited number of investigations have so far been conducted into communication between self-driving cars and pedestrians. For example, when a pedestrian is about to cross a street, that pedestrian needs to know the intension of the approaching self-driving car. In the present study, we designed a novel interface known as "Eyes on a Car" to address this problem. We added eyes onto a car so as to establish eye contact communication between that car and pedestrians. The car looks at the pedestrian in order to indicate its intention to stop. This novel interface design was evaluated via a virtual reality (VR) simulated environment featuring a street-crossing scenario. The evaluation results show that pedestrians can make the correct street-crossing decision more quickly if the approaching car has the novel interface "eyes" than in the case of normal cars. In addition, the results show that pedestrians feel safer with regard to crossing a street if the approaching car has eyes and if the eyes look at them.

    Category search is a searching activity where the user has an example image and searches for other images of the same category. This activity often requires appropriate keywords of target categories making it difficult to search images without prior knowledge of appropriate keywords. Text annotations attached to images are a valuable resource for helping users to find appropriate keywords for the target categories. We propose an image exploration system in this article for category image search without the prior knowledge of category keywords. Our system integrates content-based and keyword-based image exploration and seamlessly switches exploration types according to user interests. The system enables users to learn target categories both in image and keyword representation through exploration activities. Our user study demonstrated the effectiveness of image exploration using our system, especially for the search of images with unfamiliar category compared to the single-modality image search.

    Most of computerized cognitive behavioral therapy targeted restoration and few have targeted primary prevention. The purpose of this study is to obtain the knowledge for further development on preventive mental healthcare application. We developed a personal mental healthcare application which aimed to give users the chance to manage their mental health by self-monitoring and regulating their behavior. Through the 30-day field trial, the results showed improvement of mood score through conducting of suggested action, and the depressive mood of the participants was significantly decreased after the trial. The possibility of application and further problem was confirmed.

    We present an interactive design system for designing free-formed bamboo-copters, where novices can easily design free-formed, even asymmetric bamboo-copters that successfully fly. The designed bamboo-copters can be fabricated using digital fabrication equipment, such as a laser cutter. Our system provides two useful functions for facilitating this design activity. First, it visualizes a simulated flight trajectory of the current bamboo-copter design, which is updated in real time during the user's editing. Second, it provides an optimization function that automatically tweaks the current bamboo-copter design such that the spin quality-how stably it spins-and the flight quality-how high and long it flies-are enhanced. To enable these functions, we present non-trivial extensions over existing techniques for designing free-formed model airplanes [UKSI14], including a wing discretization method tailored to free-formed bamboo-copters and an optimization scheme for achieving stable bamboo-copters considering both spin and flight qualities.

    We present a concept of using a movable background to navigate a caret on small mobile devices. The standard approach to selecting text on mobile devices is to directly touch the location on the text that a user wants to select. This is problematic because the user's finger hides the area to select. Our concept is to use a movable background to navigate the caret. Users place a caret by tapping on the screen and then move the background by touching and dragging. In this method, the caret is fixed on the screen and the user drags the background text to navigate the caret. We compared our technique with the iPhone's default UI and found that even though participants were using our technique for the first time, average task completion time was not different or even faster than Default UI in the case of the small font size and got a significantly higher usability score than Default UI.

    We propose subtle foot-based gestures named foot plantar-based (FPB) gestures that are used with sockstyle pressure sensors. In this system, the user can control a computing device by changing his or her foot plantar distributions, e.g., pressing the floor with his or her toe. Because such foot movement is subtle, it is suitable for use especially in a public space such as a crowded train. In this work, we focus on a user-defined gesture that is designed by the end-users, not developers of this system. We first conduct a guessability study that asks people what is the appropriate gesture for a specific command to control the computing device. Then, we implement a gesture recognizer with a machine learning technique. To avoid unexpected gesture activations, we also collect foot plantar pressure patterns made during daily activities such as walking, as negative training data. Finally, we conclude with several applications to further illustrate the utility of FPB gestures.

    We propose a video annotation system called "AnnoTone", which supports video-editing process such as cropping and effects generation, by embedding annotations describing contextual information of a scene, such as geo-location of the video camera and quality of performance of actors, during a recording. The system converts inputted annotation data into high-frequency audio signals, which are almost inaudible to the human ear, and transmits them from a smartphone speaker placed near a video camera. After recording, embedded annotations are extracted from video files and exploited to support video-editing. The signals are not completely inaudible to the human ear, but we confirmed that they can be removed from video files without considerable quality loss, using audio filters. We also tested the reliability of signal embedding and the durability of annotation signals against audio conversions by experiments, and showed the feasibility of the proposed technique in practical situations. We present several example applications using AnnoTone, and discuss the possibility of novel video-editing techniques realized by annotation embedding.

    Color enhancement is a very important aspect of photo editing. Even when photographers have tens of or hundreds of photographs, they must enhance each photo one by one by manually tweaking sliders in software such as brightness and contrast, because automatic color enhancement is not always satisfactory for them. To support this repetitive manual task, we present self-reinforcing color enhancement, where the system implicitly and progressively learns the user's preferences by training on their photo editing history. The more photos the user enhances, the more effectively the system supports the user. We present a working prototype system called SelPh, and then describe the algorithms used to perform the self-reinforcement. We conduct a user study to investigate how photographers would use a self-reinforcing system to enhance a collection of photos. The results indicate that the participants were satisfied with the proposed system and strongly agreed that the self-reinforcing approach is preferable to the traditional workflow.

    Parameter tweaking is one of the fundamental tasks in the editing of visual digital contents, such as correcting photo color. A problem with parameter tweaking is that it often requires much time and effort to explore a high-dimensional parameter space. To facilitate such exploration, we first present a new technique to analyze a parameter space to obtain a distribution of human preference. Our technique uses crowdsourced human computation to collect data for analysis. As a result of this analysis, the user obtains a goodness function that computes the goodness value of a given parameter set. This goodness function enables two user interfaces for exploration: Smart Suggestion, which provides suggestions of preferable parameter sets, and VisOpt Slider, which interactively visualizes the distribution of goodness values on sliders and gently optimizes slider values while the user is editing. We applied our technique to four applications with different design parameter spaces.

    We present a "Fix and Slide" technique, which is a concept to use a movable background to place a caret insertion point and to select text on a mobile device. Standard approach to select text on mobile devices is touching to the text where a user wants to select, and sometimes pop-up menu is displayed and they choose "select" mode and then start to specify an area to be selected. A big problem is that the user's finger hides the area to select this is called a "fat finger problem." We use the movable background to navigate a caret. First a user places a caret by tapping on a screen and then moves the background by touching and dragging on a screen. In this situation, the caret is fixed on the screen so that the user can move the background to navigate the caret where the user wants to move the caret. We implement the Fix and Slide technique on iOS device (iPhone) to demonstrate the impact of this text selection technique on small mobile devices.

    Architecture-scale design requires two different viewpoints: a small-scale internal view, i.e., a first-person view of the space to see local details as an occupant of the space, and a large-scale external view, i.e., a top-down view of the entire space to make global decisions when designing the space. Architects or designers need to switch between these two viewpoints, but this can be inefficient and time-consuming. We present a collaborative design system, Dollhouse, to address this problem. By using our system, users can discuss the design of the space from two viewpoints simultaneously. This system also supports a set of interaction techniques to facilitate communication between these two user groups.

    This research addresses architecture-scale problem-solving involving the design of living or working spaces, such as architecture and floor plans. Such design systems require two different viewpoints: A small-scale internal view, i.e., a first-person view of the space to see local details as an occupant of the space, and a large-scale external view, i.e., a top-down view of the entire space to make global decisions when designing the space. Architects or designers need to switch between these two viewpoints to make various decisions, but this can be inefficient and time-consuming. We present a system to address the problem, which facilitates asymmetric collaboration between users requiring these different viewpoints. One group of users comprises the designers of the space, who observe and manipulate the space from a top-down view using a large tabletop interface. The other group of users represents occupants of the space, who observe and manipulate the space based on internal views using head-mounted displays (HMDs). The system also supports a set of interaction techniques to facilitate communication between these two user groups. Our system can be used for the design of various spaces, such as offices, restaurants, operating rooms, parks, and kindergartens.

    We present the FuwaFuwa sensor module, a round, hand-size, wireless device for measuring the shape deformations of soft objects such as cushions and plush toys. It can be embedded in typical soft objects in the household without complex installation procedures and without spoiling the softness of the object because it requires no physical connection. Six LEDs in the module emit IR light in six orthogonal directions, and six corresponding photosensors measure the reflected light energy. One can easily convert almost any soft object into a touch-input device that can detect both touch position and surface displacement by embedding multiple FuwaFuwa sensor modules in the object. A variety of example applications illustrate the utility of the FuwaFuwa sensor module. An evaluation of the proposed deformation measurement technique confirms its effectiveness.

    We present facetons, geometric modeling primitives designed for building architectural models especially effective for a virtual environment where six degrees of freedom input devices are available. A faceton is an oriented point floating in the air and defines a plane of infinite extent passing through the point. The polygonal mesh model is constructed by taking the intersection of the planes associated with the facetons. With the simple interaction of faceton, users can easily create 3D architecture models. The faceton primitive and its interaction reduce the overhead associated with standard polygonal mesh modeling, where users have to manually specify vertexes and edges which could be far away. The faceton representation is inspired by the research on boundary representations (B-rep) and constructive solid geometry, but it is driven by a novel adaptive bounding algorithm and is specifically designed for 3D modeling activities in an immersive virtual environment. We describe the modeling method and our current implementation. The implementation is still experimental but shows potential as a viable alternative to traditional modeling methods.

    We propose subtle foot-based gestures named foot plantar-based (FPB) gestures that are used with sock-placed pressure sensors. In this system, the user can control a computing device by changing his or her foot plantar distributions, e.g., pressing the floor with his/her toe. Because such foot movement is subtle, it is suitable for use especially in a public space such as a crowded train. In this study, we first conduct a guessability study to design a user-defined gesture set for interaction with a computing device. Then, we implement a gesture recognizer with a machine learning technique. To avoid unexpected gesture activations, we also collect foot plantar pressure patterns made during daily activities such as walking, as negative training data. Additionally, we evaluate the unobservability of FPB gestures by using crowdsourcing. Finally, we conclude with several applications to further illustrate the utility of FPB gestures.

    We present a video annotation system called "AnnoTone", which can embed various contextual information describing a scene, such as geographical location. Then the system allows the user to edit the video using this contextual information, enabling one to, for example, overlay with map or graphical annotations. AnnoTone converts annotation data into high-frequency audio signals (which are inaudible to the human ear), and then transmits them from a smartphone speaker placed near a video camera. This scheme makes it possible to add annotations using standard video cameras with no requirements for specific equipment other than a smartphone. We designed the audio watermarking protocol using dual-tone multi-frequency signaling, and developed a general-purpose annotation framework including an annotation generator and extractor. We conducted a series of performance tests to understand the reliability and the quality of the watermarking method. We then created several examples of video-editing applications using annotations to demonstrate the usefulness of Annotone, including an After Effects plugin.

    We propose a puppet-based user interface - named Avatouch - for specifying massage position without looking at the control device. Users can indicate massage position on their backs by touching the puppet's one (Figurel). Besides, we also develop a massage chair system with both a push-button interface and Avatouch. Experimental results confirm that almost half of subjects kept Avatouch well away from their faces. Furthermore, two participants modulated massage position without looking at the plushie. In this paper, we firstly explain about Avatouch. Then, we describe a massage chair system and a user study to observe how people use each interface. At the end of this paper, we will discuss the advantage and disadvantage of Avatouch.

    We present a system called Aibiki, which can support users in practicing the shamisen, a three-stringed Japanese musical instrument, via an automatic and adaptive score scroll. We chose Nagauta, as an example of a type of shamisen music. Each piece typically lasts 10-40 min furthermore, both hands are required to play the shamisen, and it is not desirable to turn pages manually during a performance. In addition, there are some characteristic issues that are particular to the shamisen, including the variable tempo of the music and the unique timbre of the instrument, which makes pitch detection difficult using standard techniques. In this work, we describe an application that automatically scrolls through a musical score, initially at a predefined tempo. Because there is often a difference between the predefined tempo and tempo with which the musician plays the piece, the application adjusts speed of the score scroll based on the input from a microphone. We evaluated the performance of the application via a user study. We find that the system was able to scroll the score in time to the actual performance, and that the system was useful for practicing and playing the shamisen.

    In this paper, we propose a to-do list interface for sharing tasks between human and multiple agents including robots and software personal assistants. While much work on software architectures aims to achieve efficient (semi-)autonomous task coordination among human and agents, little work on user interfaces can be found for user-oriented flexible task coordination. Instead, most of the existing human-agent interfaces are designed to command a single agent to handle specific kinds of tasks. Meanwhile, our interface is designed to be a platform to share any kinds of tasks between users and multiple agents. When agents can handle the task, they ask for details and permission to execute it. Otherwise, they try supporting users or just keep silent. New tasks can be registered not only by humans but also by agents when errors occur that can only be fixed by human users. We present the interaction design and implementation of the interface, Sharedo, with three example agents, followed by brief user feedback collected from a preliminary user study.

    Parameter tweaking is one of the fundamental tasks in the editing of visual digital contents, such as correcting photo color or executing blendshape facial expression control. A problem with parameter tweaking is that it often requires much time and effort to explore a high-dimensional parameter space. We present a new technique to analyze such highdimensional parameter space to obtain a distribution of human preference. Our method uses crowdsourcing to gather pairwise comparisons between various parameter sets. As a result of analysis, the user obtains a goodness function that computes the goodness value of a given parameter set. This goodness function enables two interfaces for exploration: Smart Suggestion, which provides suggestions of preferable parameter sets, and VisOpt Slider, which interactively visualizes the distribution of goodness values on sliders and gently optimizes slider values while the user is editing. We created four applications with different design parameter spaces. As a result, the system could facilitate the user's design exploration.

    One of the difficulties with standard route maps is accessing to multi-scale routing information. The user needs to display maps in both a large scale to see details and a small scale to see an overview, but this requires tedious interaction such as zooming in and out. We propose to use a hierarchical structure for a route map, called a "Route Tree", to address this problem, and describe an algorithm to automatically construct such a structure. A Route Tree is a hierarchical grouping of all small route segments to allow quick access to meaningful large and small-scale views. We propose two Route Tree applications, "RouteZoom" for interactive map browsing and "TreePrint" for route information printing, to show the applicability and usability of the structure. We conducted a preliminary user study on RouteZoom, and the results showed that RouteZoom significantly lowers the interaction cost for obtaining information from a map compared to a traditional interactive map. © 2014 ACM.

    Programmers write and edit their source code in a text editor. However, when they design the look-and-feel of a game application such as an image of a game character and an arrangement of a button, it would be more intuitive to edit the application by directly interacting with these objects on a game window. Although modern game engines realize this facility, they use a highly structured framework and limit what the programmer can edit. In this paper, we present CapStudio, a development environment for a visual application with an interactive screencast. A screencast is a movie player-like output window with code editing functionality. The screencast works with a traditional text editor. Modifications of source code in the text editor and visual elements on the screencast will be immediately reflected on each other. We created an example application and confirmed the feasibility of our approach.

    We present an animation creation workflow for integrating offline physical, painted media into the digital authoring of Flash-style animations. Generally, animators create animations with standardized digital authoring software. However, the results tend to lack the individualism or atmosphere of physical media. In contrast, illustrators have skills in painting physical media but have limited experience in animation. To incorporate their skills, we present a workflow that integrates the offline painting and digital animation creation processes in a labor-saving manner. First, a user makes a rough sketch of the visual elements and defines their movements using our digital authoring software with a sketch interface. Then these images are exported to printed pages, and users can paint using offline physical media. Finally, the work is scanned and imported back into the digital content, forming a composite animation that combines digital and physical media. We present an implementation of this system to demonstrate its workflow. We also discuss the advantages of using physical media in digital animations through design evaluations.

    We present a series of projects for end-user authoring of interactive robotic behaviors, with a particular focus on the style of those behaviors: we call this approach Style-by-Demonstration (SBD).We provide an overview introduction of three different SBD platforms: SBD for animated character interactive locomotion paths, SBD for interactive robot locomotion paths, and SBD for interactive robot dance. The primary contribution of this article is a detailed cross-project SBD analysis of the interaction designs and evaluation approaches employed, with the goal of providing general guidelines stemming from our experiences, for both developing and evaluating SBD systems. In addition, we provide the first full account of our Puppet Master SBD algorithm, with an explanation of how it evolved through the projects. © 2014 ACM.

    We present faceton, a geometric modeling primitive designed for building architectural models, using a six degrees of freedom (DoF) input device in a virtual environment (VE). A faceton is given as an oriented point floating in the air and defines a plane of infinite extent passing through the point. The polygonal mesh model is constructed by taking the intersection of the planes associated with the facetons. With the simple drag-and-drop and group interaction of faceton, users can easily create 3D architecture models in the VE. The faceton primitive and its interaction reduce the overhead associated with standard polygonal mesh modeling in VE, where users have to manually specify vertexes and edges which could be far away. The faceton representation is inspired by the research on boundary representations (B-rep) and constructive solid geometry (CSG), but it is driven by a novel adaptive bounding algorithm and is specifically designed for the 3D modeling activities in an immersive virtual environment.

    We propose a technique called voice augmented manipulation (VAM) for augmenting user operations in a mobile environment. This technique augments user interactions on mobile devices, such as finger gestures and button pressing, with voice. For example, when a user makes a finger gesture on a mobile phone and voices a sound into it, the operation will continue until stops making the sound or makes another finger gesture. The VAM interface also provides a button-based interface, and the function connected to the button is augmented by voiced sounds. Two experiments verified the effectiveness of the VAM technique and showed that repeated finger gestures significantly decreased compared to current touch-input techniques, suggesting that VAM is useful in supporting user control in a mobile environment. © 2013 ACM.

    A scrollbar is the most basic function of a graphical user interface. It is usually displayed on one side of an application window when a displayed document is larger than the window. However, the scrollbar is mostly presented as a simple bar without much information, and there is still plenty of room for improvement. In this paper, we propose an overview scrollbar that displays an overview of the entire document on it and implemented four types of overview scrollbars that use different compression methods to render the overviews. We conducted a user study to investigate how people use these scrollbars and measured the performance of them. Our results suggest that overview scrollbars are more usable than is a traditional scrollbar when people search targets that are recognizable in overview.

    Current programming environments use textual or symbolic representations. While these representations are appropriate for describing logical processes, they are not appropriate for representing raw values such as human and robot posture data, which are necessary for handling gesture input and controlling robots. To address this issue, we propose Picode, a text-based development environment augmented with inline visual representations: photos of human and robots. With Picode, the user first takes a photo to bind it to posture data. She then drag-and-drops the photo into the code editor, where it is displayed as an inline image. A preliminary user study revealed positive effects of taking photos on the programming experience. Copyright © 2013 ACM.

    RoboJockey is an interface for creating robot behavior and giving people a new entertainment experience with robots, in particular, making robots dance, such as the "Disc jockey" and "Video jockey" (Figure 1, left). The users can create continuous robot dance behaviors on the interface by using a simple visual language (Figure 1, right). The system generates music with beat and choreographs the robots in a dance using user-created behaviors. The RoboJockey has a multi-touch tabletop interface, which gives users a multi-user collaboration every object is designed as a circle, and it can be operated from all positions around the tabletop interface. RoboJockey supports a humanoid robot, which has a capable of expressing human like dance behaviors (Figure 1, center). Copyright © 2012 ACM, Inc.

    This paper introduces DressUp, a computerized system for designing dresses with 3D input using the form of the human body as a guide. It consists of a body-sized physical mannequin, a screen, and tangible prop tools for drawing in 3D on and around the mannequin. As the user draws, he/she modifies or creates pieces of digital cloth, which are displayed on a model of the mannequin on the screen. We explore the capacity of our 3D input tools to create a variety of dresses. We also describe observations gained from users designing actual physical garments with the system. © 2012 ACM.

    The screen of a tabletop computer is often occluded by physical objects such as coffee cups. This makes it difficult to see the virtual elements under the physical objects (visibility) and manipulate them (manipulability). Here we present a user interface widget, called "SnapRail," to address these problems, especially occlusion of a manipulable collection of virtual discrete elements such as icons. SnapRail detects a physical object on the surface and the virtual elements under the object. It then snaps the virtual elements to a rail widget that appears around the object. The user can then manipulate the virtual elements along the rail widget. We conducted a preliminary user study to evaluate the potential of this interface and collect initial feedback. The SnapRail interface received positive feedback from participants of the user study. © 2012 ACM.

    We present universal earphones that use both a proximity sensor and a skin conductance sensor and we demonstrate several implicit interaction techniques they achieve by automatically detecting the context of use. The universal earphones have two main features. The first involves detecting the left and right sides of ears, which provides audio to either ear, and the second involves detecting the shared use of earphones and this provides mixed stereo sound to both earphones. These features not merely free users from having to check the left and right sides of earphones, but they enable them to enjoy sharing stereo audio with other people.

    PINOKY is a wireless ring-like device that can be externally attached to any plush toy as an accessory that animates the toy by moving its limbs. A user is thus able to instantly convert any plush toy into a soft robot. The user can control the toy remotely or input the movement desired by moving the plush toy and having the data recorded and played back. Unlike other methods for animating plush toys, PINOKY is non-intrusive, so alterations to the toy are not required. In a user study, 1) the roles of plush toys in the participants' daily lives were examined, 2) how participants played with plush toys without PINOKY was observed, 3) how they played with plush toys with PINOKY was observed, and their reactions to the device were surveyed. On the basis of the results, potential applications were conceptualized to illustrate the utility of PINOKY. Copyright 2012 ACM.

    As robots continue to enter people's everyday spaces, we argue that it will be increasingly important to consider the robots' movement style as an integral component of their interaction design. That is, aspects of the robot's movement which are not directly related to a task at hand (e.g., pick up a ball) can have a strong impact on how people perceive that action (e.g., aggressively or hesitantly). We call these elements the movement style. We believe that perceptions of this kind of style will be highly dependent on the culture, group, or individual, and so people will need to have the ability to customize their robot. Therefore, in this work we use Style by Demonstration, a style focus on the more-traditional programming by demonstration technique, and present the Puppet Dancer system, an interface for constructing paired and interactive robotic dances. In this paper we detail the Puppet Dancer interface and interaction design, explain our new algorithms for teaching dance by demonstration, and present the results from a formal qualitative study. © 2012 ACM.

    There are many toolkits for physical UIs, but most physical UI applications are not locomotive. When the programmer wants to make things move around in the environment, he faces difficulty related to robotics. Toolkits for robot programming, unfortunately, are usually not as accessible as those for building physical UIs. To address this interdisciplinary issue, we propose Phybots, a toolkit that allows researchers and interaction designers to rapidly prototype applications with locomotive robotic things. The contributions of this research are the combination of a hardware setup, software API, its underlying architecture and a graphical runtime debug tool that supports the whole prototyping activity. This paper introduces the toolkit, applications and lessons learned from three user studies. © 2012 ACM.

Design of the APIs is influenced by programming style of Graphical User Interface. Andy provides two-dimensional absolute coordinates on the surface by detecting visual markers attached to top surfaces of robots and objects from captured images of a ceiling-mounted camera. We will report the aim of the toolkit, summary of its APIs and implementation, method and results of user studies and related work.

    Robots are introduced in various environments and places such as offices and homes where we mundanely live. Particularly, one of the most expected functions of home robot is the transportation of objects in a living environment. This paper proposes an algorithm of object transportation under environments with objects. This algorithm is an expansion of the object transportation by dipole field algorithm so that robots can flexibly avoid objects. We compute the midpoints of the triangles that do not contain obstacles. We then use Dijkstra's algorithm to compute a path to move the robot to the object, and then compute a path to allow the robot to push the object to the goal using the dipole field algorithm.

    We propose a cooperative cooking robot system that operates with humans in an open environment. The system can cook a meal by pouring various ingredients into a boiling pot on an induction heating cooker and adjusting the heating strength according to a recipe that is developed by the user. Our contribution is in the design of the system incorporating robotic- and human-specific elements in a shared workspace so as to achieve a cooperative rudimentary cooking capability. First, we provide a graphical user interface to display detailed cooking instructions to the user. Second, we use small mobile robots instead of built-in arms to save space, improve flexibility, and increase safety. Third, we use special cooking tools that are shared with the robot. We hope insights obtained in this study will be useful for the design of other household systems in the future. A previous version of our system has been presented [1]. This demonstration will show an extended version with a new robot and improved interaction design.

    We present the FuwaFuwa sensor module, a round, hand-size, wireless device for measuring the shape deformations of soft objects such as cushions and plush toys. It can be embedded in typical soft objects in the household without complex installation procedures and without spoiling the softness of the object because it requires no physical connection. Six LEDs in the module emit IR light in six orthogonal directions, and six corresponding photosensors measure the reflected light energy. One can easily convert almost any soft object into a touch-input device that can detect both touch position and surface displacement by embedding multiple FuwaFuwa sensor modules in the object. A variety of example applications illustrate the utility of the FuwaFuwa sensor module. An evaluation of the proposed deformation measurement technique confirms its effectiveness. © 2011 ACM.

    Soft objects are widely used in our day-to-day lives, and provide both comfort and safety in contrast to hard objects. Also, soft objects are able to provide a natural and rich haptic sensation. In human-computer interaction, soft interfaces have been shown to be able to increase emotional attachment between human and machines, and increase the entertainment value of the interaction. We propose the FuwaFuwa sensor, a small, flexible and wireless module to effectively measure shape deformation in soft objects using IR-based directional photoreflectivity measurements. By embedding multiple FuwaFuwa sensors within a soft object, we can easily convert any soft object into a touch-input device able to detect both touch position and surface displacement. Furthermore, since it is battery-powered and equipped with wireless communication, it can be easily installed in any soft object. Besides that, because the FuwaFuwa sensor is small and wireless, it can be inserted into the soft object easily without affecting its soft properties.

    As various home robots come into homes, the need for efficient robot task management tools is arising. Current tools are designed for controlling individual robots independently, so they are not ideally suitable for assigning coordinated action among multiple robots. To address this problem, we developed a management tool for home robots with a graphical editing interface. The user assigns instructions by selecting a tool from a toolbox and sketching on a bird's-eye view of the environment. Layering supports the management of multiple tasks in the same room. Layered graphical representation gives a quick overview of and access to rich information tied to the physical environment. This paper describes the prototype system and reports on our evaluation of the system.

    We developed a networked robot system in which ubiquitous sensors support robot sensing and a human operator processes the robot's decisions during interaction. To achieve semi-autonomous operation for a communication robot functioning in real environments, we developed an operator-requesting mechanism that enables the robot to detect situations that it cannot handle autonomously. Therefore, a human operator helps by assuming control with minimum effort. The robot system consists of a humanoid robot, floor sensors, cameras, and a sound-level meter. For helping people in real environments, we implemented such basic communicative behaviors as greetings and route guidance in the robot and conducted a field trial at a train station to investigate the robot system's effectiveness. The results attest to the high acceptability of the robot system in a public space and also show that the operator-requesting mechanism correctly requested help in 84.7% of the necessary situations; the operator only had to control 25% of the experiment time in the semi-autonomous mode with a robot system that successfully guided 68% of the visitors.

    We developed a RoboJockey (Robot Jockey) interface for coordinating robot actions, such as dancing - similar to "Disc jockey" and "Video jockey". The system enables a user to choreograph a dance for a robot to perform by using a simple visual language. Users can coordinate humanoid robot actions with a combination of arm and leg movements. Every action is automatically performed to background music and beat. The RoboJockey will give a new entertainment experience with robots to the end-users.

    We introduce a technique to detect simple gestures of "surfing" (moving a hand horizontally) on a standard keyboard by analyzing recorded sounds in real-time with a microphone attached close to the keyboard. This technique allows the user to maintain a focus on the screen while surfing on the keyboard. Since this technique uses a standard keyboard without any modification, the user can take full advantage of the input functionality and tactile quality of his favorite keyboard supplemented with our interface.

    We developed a RoboJockey (Robot Jockey) interface for coordinating robot actions, such as dancing, similar to a "disc jockey" or "video jockey" who selects and plays recorded music or video for an audience, in this case, robot's actions, and giving people a new entertainment experience with robots. The system enables a user to choreograph a robot to dance using a simple visual language. Every icon on the interface is circular and can be operated from all positions around the tabletop interface. Users can coordinate the mobile robot's actions with a combination of back, forward, and rotating movements, and the humanoid robot's actions with a combination of arm and leg movements. Every action is automatically performed to background music. We demonstrated RoboJockey at a Japanese domestic symposium, and confirmed that people enjoyed using the system and successfully created entertaining robot dances.

    This paper reports a method that uses humanoid robots as a communication medium. Even though many interactive robots are being developed, their interactivity remains much poorer than that of humans due to their limited perception abilities. In our approach, the role of interactive robots is limited to a broadcasting medium for exploring the best way to attract people's interest to information provided by robots. We propose using robots as a passive social medium, in which they behave as if they are talking together. We conducted an eight-day field experiment at a train station to investigate the effects of such a passive social medium. © Springer Science & Business Media BV 2009.

    The amount of digital appliances and media found in domestic environments has risen drastically over the last decade, for example, digital TVs, DVD and Blu-ray players, digital picture frames, digital gaming systems, electronically moveable window blinds, and robotic vacuum cleaners. As these devices become more compatible to Internet and wireless networking (e.g. Internet-ready TVs, streaming digital picture frames, and WiFi gaming systems, such as Nintendo's Wii and Sony's Playstation) and as networking and WiFi home infrastructures become more prevalent, new opportunities arise for developing centralized control of these myriad devices and media into so called "Universal remote controls". However, many remote controls lack intuitive interfaces for mapping control functions to the device intended being controlled. This often results in trial and error button pressing, or experimentation with graphical user interface (GUI) controls, before a user achieves their intended action.

    The first robotic copies of real humans have become available. They enable their users to be physically present in multiple locations at the same time. This study investigates what influence the embodiment of an agent has on its persuasiveness and its perceived personality. Is a robotic copy as persuasive as its human counterpart? Does it have the same personality? We performed an experiment in which the embodiment of the agent was the independent variable and the persuasiveness and perceived personality were the dependent measurement. The persuasive agent advertised a Bluetooth headset. The results show that an android is found to be as persuasive as a real human or a video recording of a real human. The personality of the participant had a considerable influence on the measurements. Participants that were more open to new experiences rated the persuasive agent lower on agreeableness and extroversion. They were also more willing to spend money on the advertised product.

    We must give some form of a command to robots in order to have the robots do a complex task. An initial instruction is required even if they do their tasks autonomously. We therefore need interfaces for the operation and teaching of robots. Natural languages, joysticks, and other pointing devices are currently used for this purpose. These interfaces, however, have difficulty in operating multiple robots simultaneously. We developed a multi-touch interface with a top-down view from a ceiling camera for controlling multiple mobile robots. The user specifies a vector field followed by all robots on the view. This paper describes the user interface and its implementation, and future work of the project.

    Numerous robots have been developed, and some of them are already being used in homes, institutions, and workplaces. Despite the, development of useful robot functions, the focus so far has not been on user interfaces of robots. General users of robots find it hard to understand what the robots are doing and what kind of work they can do. This paper presents an interface for the commanding home robots by using stroke gestures on a computer screen. This interface allows the user to control robots and design their behaviors by sketching the robot's behaviors and actions on a top-down view from ceiling cameras. To convey a feeling of directly controlling the robots, our interface employs the live camera view. In this study, we focused on a house-cleaning task that is typical of home robots, and developed a sketch interface for designing behaviors of vacuuming robots.

    This paper reports an initial field trial with a prototype of a semiautonomous communication robot at a train station. We developed an operator-requesting mechanism to achieve semiautonomous operation for a communication robot functioning in real environments. The operator-requesting mechanism autonomously detects situations that the robot cannot handle by itself a human operator helps by assuming control of the robot. This approach gives semi-autonomous robots the ability to function naturally with minimum human effort. Our system consists of a humanoid robot and ubiquitous sensors. The robot has such basic communicative behaviors as greeting and route guidance. The experimental results revealed that the operator-requesting mechanism correctly requested operator's help in 85% of the necessary situations the operator only had to control 25% of the experiment time in the semi-autonomous mode with a robot system that successfully guided 68% of the passengers. At the same time, this trial provided the opportunity to gather user data for the further development of natural behaviors for such robots operating in real environments. Copyright 2008 ACM.

    This paper reports the findings for a humanoid robot that expresses its listening attitude and understanding to humans by effectively using its body properties in a route guidance situation. A human teaches a route to the robot, and the developed robot behaves similar to a human listener by utilizing both temporal and spatial cooperative behaviors to demonstrate that it is indeed listening to its human counterpart. The robot's software consists of many communicative units and rules for selecting appropriate communicative units. A communicative unit realizes a particular cooperative behavior such as eye-contact and nodding, found through previous research in HRI. The rules for selecting communicative units were retrieved through our preliminary experiments with a WOZ method. An experiment was conducted to verify the effectiveness of the robot, with the results revealing that a robot displaying cooperative behavior received the highest subjective evaluation, which is rather similar to a human listener. A detailed analysis showed that this evaluation was mainly due to body movements as well as utterances. On the other hand, subjects' utterance to the robot was encouraged by the robot's utterances but not by its body movements.

    Our project aims to develop robot authoring system especially for non-robotic researchers, such as cognitive psychologists, social psychologists, designers and art performers, to provide an intuitive robot operating environment, which enable them do authoring the robot as they want. Concretely, we have been developing the robot system which has the following characteristics. 1) Changing the robot's appearances and functions by attaching or removing Sub Modules, e.g., arms, tails, ears, wings, on/from Core Module. When this Sub Module was attached on Core Module (robot's base body), the particular information embed in Sub Modules is sent to the robot controller and this controller change the robot's behaviors according to the received information. 2) Authoring (editing or turning-up) the robot's behaviors with using intuitive command system not like a traditional program language (e.g., move (10.0, 0.0)), but similar to our natural language (e.g., "move," "run").

    Research on humanoid robots has produced various uses for their body properties in communication. In particular, mutual relationships of body movements between a robot and a human are considered to be important for smooth and natural communication, as they are in human-human communication. We have developed a semi-autonomous humanoid robot system that is capable of cooperative body movements with humans using environment-based sensors and switching communicative units. And we conducted an experiment using this robot system and verified the importance of cooperative behaviors in a route-guidance situation where a human gives directions to the robot. This result indicates that the cooperative body movements greatly enhance the emotional impressions of human in a route-guidance situation. We believe these results will allow us to develop interactive humanoid robots that sociably communicate with humans.

    © Springer Nature Singapore Pte Ltd. 2018. The first robotic copies of real humans have become available. They enable their users to be physically present in multiple locations simultaneously. This study investigates the influence that the embodiment of an agent has on its persuasiveness and its perceived personality. Is a robotic copy as persuasive as its human counterpart? Does it have the same personality? We performed an experiment in which the embodiment of the agent was the independent variable and the persuasiveness and perceived personality were the dependent measurements. The persuasive agent advertised a Bluetooth headset. The results show that an android is perceived as being as persuasive as a real human or a video recording of a real human. The personality of the participant had a considerable influence on the measurements. Participants who were more open to new experiences rated the persuasive agent lower on agreeableness and extroversion. They were also more willing to spend money on the advertised product.

    Christoph Bartneck's 2009 scientometric analysis of CHI conference proceedings revealed the number of Asian scientists participating in the event was small as compared with other countries. Bartneck's analysis was more broadly focused on both quantity and quality, including numbers of citations and best paper awards. The analysis focused on the quantitative analysis, including geography, organization, and author statistics due to limited space and resources. Experts employed Christoph Bartneck's idea of credit for the analysis in which one paper equaled one credit to conduct their respective investigations.

    拡張現実感（Augmented Reality; AR）におけるインタラクションを実現するインタフェースとしてハンドジェスチャやウェアラブルデバイスなどによる入力手法が研究されてきている．ARは身体を活用したインタラクションが必要となる点において,速度と精度だけでなく社会的受容性にも配慮されたインタフェースが求められている．本研究では小型かつ身体に装着できるデバイスとして小型の中指装着型トラックボールに注目する．身体装着型トラックボールはx,yの2軸だけでなく，回転操作のような3次元的な操作も可能であるためARでの利用に適しているのではないかと考えた．本稿では身体装着型トラックボールを使用することの有用性と実用性について調査するため，身体装着型トラックボールを含む3種類の入力手法の比較実験を行った．その結果，身体装着型トラックボールは既存手法に対し補完的な入力を提供し，球を転がす触覚フィードバックやユーザの指の大きさに依存しないデバイスの特性がARでのインタラクションにおいて有用な操作方法である可能性が示唆された．

    本研究では人が「犬派」か「猫派」の判断を下すときに，動物の外見や動作といったどのような属性を重視しているのか検証した．多くの人はペットに対する好みに基づいて，自分を「犬派」か「猫派」のどちらかであると認識し，先行研究ではこれらのタイプの間には性格の違いがあるということが判明している．本研究では，特に社会的支配志向の特性が高い人は犬のような従順なペットを好む傾向があり，人は自分の性格を補完してくれるペットを好むという研究に注目し，実験・考察を行う．実験では予備実験として犬型ロボット「aibo」と猫型ロボット「Marscat」に実装した動作がそれぞれどのような動物の動作であると感じるか，クラウドソーシングを用いて調査を行った．これをもとに本実験では回答者の社会的支配志向のスコアと動物型ロボットへの評価スコアを比較し，その結果を考察した．

    ユーザの両目の視線方向を用いて，ユーザの注視点の深度（視線深度）を推定する手法が存在する．視線深度が明らかである場合ユーザの三次元注視点が分かるため，視線深度を用いることで二次元環境では設計できないような視線インタフェースデザインが可能となる．しかし視線深度の推定精度は低く，さらに目標物がない場合は特定の深度に視線を固定することが難しいため，視線深度を活用した精度の高いインタラクションを実現することは困難である．我々はユーザの視線位置を示すポインタである視線カーソルをインタラクション領域の前方に固定し，注視目標とすることで特定の視線深度への注視を容易に行う手法を提案する．本稿では提案手法のパラメータ調査を目的とした視線カーソル選択タスクに関する実験を行った．実験の結果から，視線カーソルを配置すべき深度や深度バッファ，適切な滞留時間が明らかになった．

    三次元 VR 環境ではターゲットが他のオブジェクトに部分的に遮蔽され可視領域が狭まり，視線入力によるターゲット選択が困難となる場合がある．我々は視線と頭部方向の成す角度（視線角度）25°-45°の領域（Kuiper Belt）を活用した VR 環境における遮蔽された小さなオブジェクトの選択手法を提案する．本手法では選択候補の決定と，選択候補に対応したメニューアイテムの選択によってターゲットを選択する．メニューアイテムは Kuiper Belt に配置されており，選択候補が決定される領域（視線角度 25°以下の領域）とメニューアイテム選択領域が明確に分離されているため，Midas Touch が生じずに視線のみで選択を完了することが可能である．提案手法のユーザビリティ調査を目的として，最大 256 個のオブジェクトが密集した環境において部分的にターゲットが他のオブジェクトに隠れた状態で選択タスクを行った．実験の結果，オブジェクトが密集し，ターゲットが部分的に隠れた状態においても，提案手法は通常の視線入力手法よりも小さなオブジェクトの選択が容易であることが確認された．

    日常生活において周囲が低照度である環境は多く存在し，更には災害時などでしばし十分な光源が得られないことがある．このような環境では視覚的認知機能が低下するため，作業効率の低下や障害物衝突などの事故が発生し得る．本研究では低照度環境におけるタスク支援を目的として，MR 向けの低照度環境に対する深度情報提示手法を提案する．現在流通している MR デバイスは低照度での動作を想定していないため，VR を用いた仮想空間で低照度環境の再現を行い，提案手法が低照度における探索作業の効率を改善できるか調査した．

    Virtual Reality（VR）においてレイは広く活用されており，拡張性に優れた手法である．一方で，ハンドヘルド Augmented Reality（AR）においては，VR と同様の操作性を有したレイを実装することは難しい．これは，眼前にハンドヘルドデバイスを掲げる必要があるために，ハンドヘルドデバイスを一定以上回転させることが出来ず，VR コントローラーが持つ回転の 3 自由度を AR 操作時に表現することが難しいためである．ゆえに本研究では，バーチャルジョイスティックを用いてレイの回転に関する自由度を補完する手法と，ハンドヘルド AR における他のオブジェクト選択手法を比較し，ユーザビリティ調査を行った．

    社会生活へバーチャルエージェントが活用されたシステムが浸透してきている．バーチャルエージェントを用いたシステムの活用にはユーザの信頼が必要不可欠であるが，近年の研究により，人々はアルゴリズムの性能が人間を上回ることを認知していても，アルゴリズム自体への忌避感によって，アルゴリズムを信頼しにくい「アルゴリズム嫌悪」という現象があることが明らかになってきた．しかし，この「アルゴリズム嫌悪」とバーチャルエージェントの外見・音声の間の関連性については明らかになっている部分が少ない．本論文では，人間に情報を提供するバーチャルエージェントの外観や音声を変化させることにより，「アルゴリズム嫌悪」に影響を及ぼす信頼感がどのように変化するかを，実験を通して検討する．

    スマートフォンにおける操作方法として，搭載されたジャイロセンサを利用した 3 自由度の傾け操作がある．端末の傾きを利用した操作に関する研究（例えば，チルト操作など）は行われているが，操作方法，操作感度などのパラメータ設定の検討は十分ではない．そこで本研究では，スマートフォンの画面上に表示されたスライダーを操作するタスクを用いて，端末の傾きをスライダーの変化量に対応させる手法（Position 手法）と傾きを変化率に対応させる手法（Rate 手法）について，パラメータ設定の比較，検討を行った．本研究ではスマートフォンを横向きに持ち，端末の画面に対して垂直な方向を軸とした回転（Yaw 回転）を傾きとして利用した．Yaw 回転を利用することで画面は常に利用者の方を向く．スマートフォンを左右に傾けてスライダーを指定された位置に移動させ，その操作完了時間と精度，ユーザビリティで評価を行った．その結果，操作完了時間と精度において，左右に最大 30 度傾けることのできる操作感度の Position 手法が優れている傾向が見られたものの有意差は確認されなかった．

    被写体をテーブル上に表示し，全周囲から立体的に視聴可能な映像表示技術は，エンターティンメント分野や産業分野での幅広い応用が考えられる．我々はこれまで，複数のユーザがテーブルトップ型ディスプレイの周囲 360 度好きな方向から，その角度に応じた 3D 映像を同時に視聴できるスクリーンシステムを提案した．このシステムでは，水平方向に対してなめらかな運動視差を提示できる一方，ユーザの身長差への対応や，視点の上下移動といった垂直方向の運動視差の提示は困難であった．そこで本稿では，スクリーン中心に設置した 360 度カメラの映像から画像認識によってテーブル周囲のユーザの視点位置を検出し，ユーザに提示する視点画像の仮想カメラを上下させることで垂直視差を再現する手法を提案する．この手法により，身長差のある複数のユーザの視聴や上下方向に視点移動を行った場合でもそれぞれのユーザに正確な３D 映像を提示できる．我々は提案手法を実装し，テーブル周囲のユーザの視点位置に合わせて対応する視点画像をリアルタイムに変更できることを確認し，垂直視差再現への提案手法の有効性を示した．

    日本の伝統楽器の一つ三味線は，演奏会においては暗譜演奏が慣例となっている．また，頻繁に変化する演奏速度や独特のフォーマットの譜面などの特徴は，暗譜のための練習を難しくしている．そこで本研究では，予め与えられた速度情報に則り譜面を自動スクロールし，演奏者が画面を見るだけで演奏できるシステムを提案する．加えて，本システムではマイク入力された演奏を元に譜本上で演奏箇所の探索を行い，演奏箇所が画面に収まるよう譜面スクロール速度を適応的に調整する．実装後に各機能の性能評価を行った結果，音高推定精度にはまだ改善の余地があるが，その結果を用いた楽譜探索には概ね成功し，ユーザの演奏に合わせた楽譜スクロールが可能になった．またユーザテストにおいては，参加者数は少ないもののこのシステムが演奏練習支援につながるという評価を得られた．

    Controlling appliances, such as television sets and airconditioning units, in foreign countries is difficult because labels on the control devices (i.e., remote controls) are written in unfamiliar languages. We present a multilanguage user interface for home appliances on NFC-enabled smartphones to address this problem. The user first taps the remote of a home appliance with the smartphone. The smartphone then reads the ID from the NFC tag embedded in the remote and displays a visual copy of the remote. The text labels on the remote are automatically translated to the language of the user by reading the default configuration of the smartphone. The user can directly control home appliances with the smartphone when a network control is enabled.

    We present the FuwaFuwa sensor module, a round, hand-size, wireless device for measuring the shape deformations of soft objects such as cushions and plush toys. It can be embedded in typical soft objects in the household without complex installation procedures and without spoiling the softness of the object because it requires no physical connection. Six LEDs in the module emit IR light in six orthogonal directions, and six corresponding photosensors measure the reflected light energy. One can easily convert almost any soft object into a touch-input device that can detect both touch position and surface displacement by embedding multiple FuwaFuwa sensor modules in the object.

    We propose an operating method for bipedal robots by using two-fingered gestures on a multi-touch surface. We focus on finger gestures that people represent the human with moving fingers, such as walking, running, kicking and turning. These bipedal gestures are natural and intuitive enough for the end-users to control the humanoid robots. The system captures those finger gestures on a multi-touch display as the direct operation method. The capturing method is easy and simple, but robust enough for the entertainment applications. We show an example application with our proposed method, and demonstration at the international exhibition. We conclude with the results of observation and future implementation of our method.

    Robots are introduced in various environments and places such as offices and homes where we mundanely live. Particularly, one of the most expected functions of home robot is the transportation of objects in a living environment. This paper proposes an algorithm of object transportation under environments with objects. This algorithm is an expansion of the object transportation by dipole field algorithm so that robots can flexibly avoid objects. We compute the midpoints of the triangles that do not contain obstacles. We then use Dijkstra's algorithm to compute a path to move the robot to the object, and then compute a path to allow the robot to push the object to the goal using the dipole field algorithm.

    本稿ではこれからのエンタテインメントコンピューティング (EC) の研究において、その歴史調査の重要性について論じる。EC 研究を推進していく上では、まず歴史調査により研究の方向性や正統な評価を定めていく必要がある。また、調査結果に基いた教育用資料を作成することで、EC 分野での人材育成や、EC 研究の必要性・有用性を社会に対して発信していくべきである。最後に、EC の歴史調査を進めていく上での過去の製品・研究の動態保存について、その重要性を論じる。We discuss the importance of the study of the history of Entertainment Computing (EC) in this paper. To promote the research in EC, the study of its history is needed to evaluate research quality and design the goal of the field. The study is also essential for educational purpose for human resource development and promotion of the importance of the research in EC to our society. Finally we discuss what we should do to study the history including active preservation of products.

    Recently, various kinds of home robots have been developed and are getting common in our lives. However, most of the users of home robots do not have the knowledge of hardware and robotics, so they should not be compelled to do any troublesome procedures and manipulation. In this paper, we introduce an intuitive interface for simple and direct manipulation of home robots, focusing on how to interact with robots when use them. In particular, our system adopts pen-stroke gesture as an input command on computer screen. We designed and implemented several types of gestural commands representing corresponding tasks, and then conducted some usability experiments.

    Cognitive behavioral therapy (CBT) has become a major means to treat mental health issues. Given the high prevalence of the issues in Japan, it is an urgent task to provide patients with CBT properly. Meanwhile, there has long been a problem with patients not visiting a clinician, even when there is a mental health issue, and research into the service gap, that is, the difference between the need for and uptake of mental health services, has been ongoing.In order to fill the gap, first, we developed internet-based CBT(ICBT) and website to treat the issues. Next, we made a portal site to leads to the website and the apps of ICBT. RCT research indicated that it increased mental health literacy and decreased self-stigma significantly. Then, we added the online guide by psychologists and developed the detailed manual. Finally, we again conducted RCT research, which showed the empathetic communication facilitated by the guide developed the working alliance to complete the ICBT.

    We create a system that supports domestic robots for performing household tasks by utilizing a crowdsourcing. We consider that this makes it easy to create maps of a house, detect a location of an object, and perform a complex task by utilizing the crowdsourcing. On the other hand, there are some concerns to use the crowdsourcing services, such as 1) real-time operation, 2) privacy issue, and 3) designing an appropriate user interface. In this research, we created a proof-of-concept prototype system and conducted an experiment to investigate the appropriateness of the system.

    研究題目に沿い、本研究においては対話ロボット用のOS、特にロボットに詳しくない者においても簡単にロボット用のアプリケーションを開発することができる環境の開発を行った。ロボットが社会に広く普及するためには、多くのユーザによってそのアプリケーション開発が行われることが重要であり、本研究はこれを実現する環境を提供することを目的としていた。この環境の開発については前年度にプロトタイプの開発が終了しており、本年はこれの評価を行うために、実際にロボットのアプリケーションの開発を行った。 具体的には1)タブレットPCを用いた柔軟な家庭用ロボットへの指示インタフェースの開発を行った。ここで開発された技術はUpper Austria University of Applied Sciences, Media Interaction研究室との共同研究プロジェクトに応用され、実際に使われている。2)家庭用ロボットとの共同作業により、実際に調理を行うことができるロボットシステムの開発を行った。3)ロボットに不慣れなユーザであっても簡単にロボットを用いたエンタテインメントを経験できるような直感的なインタフェースの開発を行った。これは主に二つのプロジェクトで行われ、どちらも実際に国内会議、および国際会議においてデモンストレーションを行った。現在はさらに自然なインタラクションによるロボットとの対話技術の実現に関する研究を行っており、これについても前年度に開発した環境が重要な役割を担っている。これらのアプリケーション開発とデモンストレーションを通して、実社会におけるロボットの役割や存在意義について示していくことは分野発展のために非常に重要であると考えている。 また、これらの開発を通じて得られた結果は、実際に現在の対話ロボット用OSの開発に生かされており、有効なフィードバックが働いていると考えている。
