  • SealMates: Supporting Communication in Video Conferencing using a Collective Behavior-Driven Avatar

    Armstrong M., Yang C.L., Skiers K., Lim M., Gunasekaran T.S., Wang Z., Narumi T., Minamizawa K., Pai Y.S.

    Proceedings of the ACM on Human-Computer Interaction （Proceedings of the ACM on Human-Computer Interaction)  8 （ CSCW1 ） 1 - 23 2024.04

    　View Summary

    The limited nonverbal cues and spatially distributed nature of remote communication make it challenging for unacquainted members to be expressive during social interactions over video conferencing. Though it enables seeing others' facial expressions, the visual feedback can instead lead to unexpected self-focus, resulting in users missing cues for others to engage in the conversation equally. To support expressive communication and equal participation among unacquainted counterparts, we propose SealMates, a behavior-driven avatar in which the avatar infers the engagement level of the group based on collective gaze and speech patterns and then moves across interlocutors' windows in the video conferencing. By conducting a controlled experiment with 15 groups of triads, we found the avatar's movement encouraged people to experience more self-disclosure and made them perceive everyone was equally engaged in the conversation than when there was no behavior-driven avatar. We discuss how a behavior-driven avatar influences distributed members' perceptions and the implications of avatar-mediated communication for future platforms.

    　View Summary

    The use of wearable sensor technology opens up exciting avenues for both art and HCI research, providing new ways to explore the invisible link between audience and performer. To be effective, such work requires close collaboration between performers and researchers. In this article, we report on the co-design process and research insights from our work integrating physiological sensing and live performance. We explore the connection between the audience's physiological data and their experience during the performance, analyzing a multi-modal dataset collected from 98 audience members. We identify notable moments based on HRV and EDA, and show how the audience's physiological responses can be linked to the choreography. The longitudinal changes in HRV features suggest a strong connection to the choreographer's intended narrative arc, while EDA features appear to correspond with short-term audience responses to dramatic moments. We discuss the physiological phenomena and implications for designing feedback systems and interdisciplinary collaborations.

    　View Summary

    <p>Information technologies, such as IoT, artificial intelligence (AI), and virtual reality (VR), have seen so much development that there is now a wide variety of digital equipment incorporated into the infrastructure of daily life. From the agrarian society (Society 1.0) through the information society (Society 4.0), humankind has created farmlands and cities by structuring natural environments physically and has built information environments by structuring them informationally. However, despite the rapid development of information environments, it may be fair to say that the perspectives of the human body have not changed at all since the industrial revolution.</p><p>In the context of these recent technological developments, greater attention is being paid to human augmentation studies. These studies aim for a new embodiment of “human-computer integration,” one which can physically and informationally compensate or augment our innate sensory functions, motor functions, and intellectual processing functions by using digital equipment and information systems at will, as if they were our hands and feet. It has also been proposed that the technical systems that enable us to freely do what we want by utilizing human augmentations be called “JIZAI” (freedomization) as opposed to “automation.”</p><p>The term “JIZAI body” used in these studies represents the new body image of humans who will utilize engineering and informatics technologies to act at will in the upcoming “super smart society” or “Society 5.0.” In these studies, human augmentation technologies are an important component of JIZAI, but JIZAI is not the same as human augmentation. JIZAI is different in scope from human augmentation, as it aims to enable humans to move freely among the five new human body images: “strengthened sense” (augmented perception), “strengthened physical body” (body augmentation), “separately-designed mind and body” (out of body transform), “shadow cloning,” and “assembling.” In the society of the future where JIZAI bodies widely prevail, we will use technologies that enable us to do what we have failed at or given up due to limitations of our physical bodies. We believe that a future society, one in which aging does not reduce our capabilities but instead increased options give us hope, can be realized. This special issue, consisting of two review papers and twelve research papers, deals with diverse and wide-ranging areas, including human augmentation, robotics, virtual reality, and others. We would like to express our sincere appreciation to all the authors and reviewers of the papers contributed to this special issue and to the editorial committee of the Journal of Robotics and Mechatronics for their gracious cooperation.</p>

    本計画研究は、「デジタル身体性経済学」を創成するための、情報ネットワーク基盤に関する学術を構築する。具体的には、デジタル身体性情報（触覚の振動情報や心拍等の生体情報）が人と人の間で伝送・共有されたときに、それが人の情動・行動へどのような影響を及ぼすのか検討するとともに、その効果を奏するためのネットワーク技術の設計を行う。
    本計画研究の目的は「デジタル身体性経済学」を創成するための、情報ネットワーク基盤に関する学術を構築することである。具体的には、人間が何かに触れる際の振動や力、心拍や呼吸といった生体情報に代表される身体性情報をデジタル化し、生来の認知行動システムを阻害しない形で計測、伝送するとともに、共感や信頼、利他行動を生み出すような提示手法を検討する。
    1年目の2021年度は、振動や圧力を1対1の状況において双方向で伝達したり、振動を多対多の状況で共有することで、向社会行動がどのように誘発されるのかを検証するために、その計測・伝送・提示技術に関する検討を行った。2年目の2022年度（本年度）では、実際に、遠隔で圧力を伝送し合う状況における心理的・生理的変化を計測する実験を行った。また、お互いに触覚を感じながら経済ゲームを行う事で、向社会的な行動が変化するかを検証した。触覚と経済ゲームの組み合わせはこれまでほとんど行われておらず、その新規性は高い。また、触覚による影響は、その触質感の違いや、コミュニケーションの在り方や経済ゲームの種類によって、異なる可能性もあり、来年度はその整理を行っていきたい。これらの成果は、国内学会・国際学会にて発表された。また、デジタル技術を介してどのように、社会的な行動が引き起こされるのか、映像と触覚フィードバック技術を組み合わせた影響や、分散型データベース技術におけるNFT（Non-fungible Token）の保有による影響を、身体論からも考察した。
    研究の方向性や進捗については当初の予定通りであり、順調に進捗している。また、領域内のメンバー間で密にコミュニケーションをとることで、協力しながら 研究を進められている。
    研究の方向性はこれまで通り、「デジタル身体性経済学」を創成するための、情報ネットワーク基盤に関する学術を構築することである。一年目・二年目と進めてきた、 身体性情報をデジタル化し、伝送・提示に関する整理を行うとともに、向社会行動を生み出す触覚提示手法の検討を継続する。

    　View Summary

    In this study, with the aim of constructing a "body conjugate system" that projects our body image to control targets in various shapes, we studied on design guidelines and design limits of the body conjugate system by using VR avatars and wearable robots. We examined our cognition on the body conjugate system in the case of constructing it with not only the whole body but also with the local elements of the body. As a result of this study, we acquired the concept of "body schema editing" according to physical tasks.
