    Abstract Research efforts have previously explored various components of physical/virtual workspaces that adaptively interact with knowledge workers in order to support them in their work. In this paper, we propose an encompassing framework for these efforts, which we refer to as Human-Workspace Interaction (HWI), with the goal of increasing awareness and understanding of the research area and encouraging its further development. Specifically, we present a taxonomy of HWI focusing on the types of components, research approaches, interaction targets and objectives, and then review the prior research efforts over the past two decades based on these criteria. Finally, we discuss challenges to further advance the development of HWI and future prospects, taking into account the impact of the societal changes caused by the COVID-19 pandemic.

    We propose HandyGaze, a 6-DoF gaze tracking technique for room-scale environments that can be carried out by simply holding a smartphone naturally without installing any sensors or markers in the environment. Our technique simultaneously employs the smartphone’s front and rear cameras: The front camera estimates the user’s gaze vector relative to the smartphone, while the rear camera (and depth sensor, if available) performs self-localization by reconstructing a pre-obtained 3D map of the environment. To achieve this, we implemented a prototype that works on iOS smartphones by running an ARKit-based algorithm for estimating the user’s 6-DoF head orientation. We additionally implemented a novel calibration method that offsets the user-specific deviation between the head and gaze orientations. We then conducted a user study (N=10) that measured our technique’s positional accuracy to the gaze target under four conditions, based on combinations of use with and without a depth sensor and calibration. The results show that our calibration method was able to reduce the mean absolute error of the gaze point by 27%, with an error of 0.53 m when using the depth sensor. We also report the target size required to avoid erroneous inputs. Finally, we suggest possible applications such as a gaze-based guidance application for museums.

    Head-mounted displays (HMDs) increase immersion into virtual worlds. The problem is that this limits headset users' awareness of bystanders: headset users cannot attend to bystanders' presence and activities. We call this the HMD boundary. We explore how to make the HMD boundary permeable by comparing different ways of providing informal awareness cues to the headset user about bystanders. We adapted and implemented three visualization techniques (Avatar View, Radar and Presence++) that share bystanders' location and orientation with headset users. We conducted a hybrid user and simulation study with three different types of VR content (high, medium, low interactivity) with twenty participants to compare how these visualization techniques allow people to maintain an awareness of bystanders, and how they affect immersion (compared to a baseline condition). Our study reveals that a see-through avatar representation of bystanders was effective, but led to slightly reduced immersion in the VR content. Based on our findings, we discuss how future awareness visualization techniques can be designed to mitigate the reduction of immersion for the headset user.

    Building higher-quality image classification models requires better performance analysis (PA) to help understand their behaviors. We propose ConfusionLens, a dynamic and interactive visualization interface that augments a conventional confusion matrix with focus+context visualization. This interface allows users to seamlessly switch table layouts among three views (overall view, class-level view, and between-class view) while observing all of the instance images in a single screen. We designed and implemented a ConfusionLens prototype that supports hundreds of instances, and then conducted a user study (N \(=\) 14) to evaluate it compared to the conventional confusion matrix with a split view of instances. Results show that ConfusionLens achieved faster task-completion time in observing instance-level performance and higher accuracy in observing between-class confusion. Moreover, we conducted an expert interview (N \(=\) 6) to investigate the applicability of our interface to practical PA tasks, and then implemented several extensions of ConfusionLens based on the feedback. Feedback on these extensions from users experienced in image classification (N \(=\) 5) demonstrated their general usefulness and highlighted their beneficial use in PA tasks.

    Room-scale VR has been considered an alternative to physical office workspaces. For office activities, users frequently require planar input methods, such as typing or handwriting, to quickly record annotations to virtual content. However, current off-the-shelf VR HMD setups rely on mid-air interactions, which can cause arm fatigue and decrease input accuracy. To address this issue, we propose UbiSurface, a robotic touch surface that can automatically reposition itself to physically present a virtual planar input surface (VR whiteboard, VR canvas, etc.) to users and to permit them to achieve accurate and fatigue-less input while walking around a virtual room. We design and implement a prototype of UbiSurface that can dynamically change a canvas-sized touch surface's position, height, and pitch and yaw angles to adapt to virtual surfaces spatially arranged at various locations and angles around a virtual room. We then conduct studies to validate its technical performance and examine how UbiSurface facilitates the user's primary mid-air planar interactions, such as painting and writing in a room-scale VR setup. Our results indicate that this system reduces arm fatigue and increases input accuracy, especially for writing tasks. We then discuss the potential benefits and challenges of robotic touch devices for future room-scale VR setups.

    We propose a novel phone-case-shaped interface named TetraForce, which enables four types of force input consisting of two force directions (i.e., pressure force and shear force) and two force-applied surfaces (i.e., touch surface and back surface) in a single device. Force detection is achieved using the smartphone's built-in magnetometer (and supplementary accelerometer and gyro sensor) by estimating the displacement of a magnet attached to a 3-DoF passively movable panel at the back. We conducted a user study (N=12) to investigate the fundamental user performance by our interface and demonstrated that the input was detected as intended with a success rate of 97.4% on average for all four input types. We further conducted an ideation workshop with people who were involved in human-computer interaction (N=12) to explore possible applications of this interface, and we obtained 137 ideas for applications using individual input types and 51 possible scenarios using them in combination. Organizing these ideas reveals the advantages of each input type and suggests that our interface is useful for applications that require complex operations and that it can improve intuitiveness through elastic feedback.

    We propose a novel entertainment device for flipbooks called Paranga that embodies both physical features of paper and e-book interactivity. To reproduce flipbook experience, requirements for the implementation were determined through a preliminary study to observe users' behaviors while page turning. Based on the requirements, we created a book-shaped device employing a rotatable roller mechanism with pieces of real paper. The device detects how quickly a user is turning pages and provides a user with visual, tactile, and auditory feedbacks. Using this device, we implemented several interactive flipbook installations in which the story changes depending on page-turning speed. From the results of user study, we confirmed that the page-turning interaction was regarded as similar to a paper-based book and that the installations entertained the users.

    This study experimentally examines relationships between such nonverbal behaviors as degree of speech, hand gestures, head direction and body distance, and subjective evaluation of an activity of atmosphere created during a six-person conversation, in order to establish an estimation model of atmosphere in interpersonal communication. A conversation group consisted of three males and females who met for the first time, and they talked for 12 minutes overall and rated the activity of atmosphere during conversation. Our results with regression analysis shows that speech time, crosstalk with 4 persons, hand gestures, and size of conversational space had high correlation with the subjectively rated atmosphere. Throughout some analyses, we discussed fitness of the several regression models compared to the estimation model for triadic conversation.

    We propose an umbrella-like device called Funbrella that entertains people with many types of rain by focusing on an umbrella as a user interface that connects humans and rain. Generally, people experience rain with sound, sight, or sometimes smell; however, in our proposed system, we exploit the vibration perceived through an umbrella's handle so that people can feel the rain. We implemented a vibration-giving mechanism based on a dynamic microphone and a dynamic speaker whose structures are almost identical. With this structure, Funbrella records the vibrations caused by raindrops and plays them. We implemented two applications: Crazy Rain and Tele-rain. One is to feel various kinds of rain, and the other transmits rain to different places in real time. With such applications, people can enjoy rain that is usually annoying.

    Rain changes its complexion based on the time and the place. Each aspect of rain provides a unique impression, so experiencing it in distant places and different times would be a new way of sharing information. To represent rain, we focused on an umbrella as a user interface to connect humans and rain. Generally, people experience rain with sounds, sights, or sometimes smells; however, in our proposed system, we exploit the vibration perceived through an umbrella's handle to let people feel the rain. With Funbrella, you will find how many complexions rain has because it gives you opportunities to feel and enjoy various kinds of rain that is recorded as real vibration data with itself.

    This research aimed to solve the problems of arm fatigue and deterioration of input accuracy during aerial interactions in room-scale VR by using a variety of robotic props. Specifically, we developed technology to have a robot circle around a user wearing an HMD and provide physical support to the user when physical instructions or highly accurate input is required. We then applied this to multiple robots and developed technology to present various tactile sensations at multiple points in room-scale VR. Furthermore, we demonstrated that the advantages of a large robot-type device can be utilized to apply this technology to control the orientation of the body in room-scale VR. Through experiments, we clarified that in both cases, physical support for VR users reduces fatigue and improves the sense of realism.

    Dexterous 3D motion data can be used for multiple purposes: biologists can use the data to record detailed movements of small animals in their living environments, scientists can track the flow of fluids, and researchers can track finger movements and objects being manipulated by users in virtual reality. We have captured dexterous 3D motion data from a flexible magnetic flux sensor array, using deep learning and a structure-aware temporal bilateral filter. We invented our new method by applying these ideas on a new magnetic tracking principle. First, the neural networks learn the regression from the simulation flux values to the LC coils 3D configuration at any location and orientation. The new filter further compensates the data to reconstruct smooth and accurate motion. Markers do not require batteries, so observation time can be maximized. As a result, the new integrated system can track multiple LC coils at 100Hz speed at millimeter level accuracy.

    空間把握のインタフェースとしては,紙や布を指で縮めようとしたときに発生する「撓(たわ)み」のメタファをスクロールやズーム操作に適用したビューポート制御手法を提案した.この手法は表示するコンテンツを伸縮性の柔らかい材質と捉えており,通常のスクロールでは画面外へ押し出されていた領域が,コンテンツが歪められることによりビューポートに残るため,可視性の向上や直感的な操作が期待される.本年度はこの研究をさらに押し進め,マルチタッチディスプレイの環境でのスクロール・ズームの統合的手法の設計を設計し,これらのパフォーマンスをユーザスタディにより評価した.この内容について発表したヒューマンインタフェースシンポジウム2011ではその新規性が評価され,学術奨励賞を受賞した.状況把握のためのインタフェースのとして,多人数でのコミュニケーションを支援する情報環境Ambient Suiteというコンセプトを提案した.Ambient Suiteは部屋全体が入出力機能を持ったシステムであり,様々なセンサにより会話の状態を推定し,また,この状態に応じて,床や壁に配置されたディスプレイ群を連携させて様々な情報を表示することで会話の活性化を目指す.本年度は,Ambient Suiteを立食パーティの場面に適用したAmbient PartyRoomを実装し,この環境を用いた初対面の男女6人1グループとする会話実験を,17グループに対して行った.この結果,本システムが会話の状況を十分に推定可能な性能を有し,情報提示により会話を活性化させられることがわかった.この内容については国際会議で発表し,国内の学術論文に投稿済みである.
