Since its establishment in 1935, the Research Institute of Electrical Communication (RIEC) at Tohoku University has been conducting research on fundamental technologies for the realization of rich telecommunication. 

Tele-communications can be simply modeled as communication between people in the real/physical world via the virtual/cyber world. However, the current telecommunication system does not always realize rich communication because it lacks important information. Therefore, we believe that the realization of a system that can successfully transmit the subtleties of nonverbal information is an important key to achieving rich telecommunication. With financial support from the Ministry of Education, Culture, Sports, Science and Technology (MEXT), in April 2023, we established the Interdisciplinary ICT Research Center for Cyber and Real Spaces within the RIEC and began research to enrich telecommunication with nonverbal information.

In this symposium, we invite world leaders who have been/will be leading the related research fields and think about the future of "enriching telecommunication with nonverbal information" together with you.

東北大学 電気通信研究所では、1935年の開所以来、人間性豊かなコミュニケーションの実現に向けた基盤技術の研究を進めてまいりました。

遠隔コミュニケーションは、リアルな空間にいる人が遠くのリアルな空間にいる人と電気通信技術を用いてコミュニケーションをするものとモデル化できます。しかし、現状の遠隔コミュニケーションのシステムでは大切な情報が欠落してしまうため、必ずしも豊かなコミュニケーションが実現できているとは言えません。そこで我々は、非言語情報の機微をうまく伝送できる仕組みを実現することが、人間性豊かなコミュニケーションを実現するための重要な鍵だと考えました。そして2023年4月に、文部科学省より財政支援を受け、電気通信研究所内にサイバー&リアルICT学際融合研究センターを設置し、「非言語情報通信で拓く豊かな遠隔コミュニケーション」の研究を開始しました。

本シンポジウムでは、関係する研究分野をこれまで牽引されてきた/これからも牽引される世界的なリーダーの先生方をお招きし、「非言語情報通信で拓く豊かな遠隔コミュニケーションの未来について、皆さんと一緒に考えてみたいと思います。

Abstract: In future telecommunications, it is expected that people will be able to communicate with each other in the cyber/virtual space with objects and information from the physical/real space they are located. The successful key to realize such rich telecommunication is to unlock “communication with nonverbal information” by appropriately conveying the subtleties of “non-spoken signals,” which plays an important role in our daily interpersonal understanding.

In April 2023, the Research Institute of Electrical Communication, Tohoku University has established a new Interdisciplinary ICT Research Center for Cyber and Real Spaces to accelerate research and development of “telecommunication with nonverbal information” through interdisciplinary collaboration. This center will synergize basic and applied AI research, networks and security, human sciences (psychology, brain sciences), human-computer interactions, and VR/AR/MR communication technologies, to impact the society with the research results. I will give an overview of these new research activities.

The Role of Nonverbal Communication in Human Relationships: Advancement of Interpersonal Communication Research in Social Psychology

Ikuo Daibo / 大坊 郁夫

President at Hokusei Gakuen University (北星学園大学)

Professor Emeritus at Osaka University

Abstract: We humans interact with one another, build relationships, and expand our social circles. Based on the code of conduct individuals rely upon, they behave accordingly and communicate various messages laden with many different meanings, using various communication channels. And those interaction processes are regarded as interpersonal communication in the field of social psychology. This talk introduces how verbal and nonverbal messages are exchanged, perceived, and interpreted by referring to the communication rules each individual has. The intersection of social psychology and information science is also mentioned. With technological developments in information and computer sciences, the efficacy and accuracy of communication behavior research in social psychology have been significantly improved, which are contributing to further theoretical understanding of nonverbal dynamics during communication. This kind of interdisciplinary collaborations could help achieve smooth communication between individuals, foster mutual understanding among them, and push us one step closer to the realization of a well-being society.

Bio: Ikuo Daibo is President of Hokusei Gakuen University and Professor Emeritus of Osaka University. He studied at Hokkaido University at both the undergraduate and graduate levels. In 2012, he retired from Osaka University and became the president at Tokyo Future University in the same year. Since 2018, he has been the president of Hokusei Gakuen University. He has served as president of the Japanese Society of Social Psychology and the Language and Social Science Society. Currently, he is an honorary member of several academic societies, including the Japanese Psychological Association. He has been also a member of the British Psychological Society, the Asian Association of Social Psychology, and the International Communication Association.

His research focuses on interpersonal communication (both verbal and nonverbal), the development and breakdown of interpersonal relationships, and communication skill training. In addition to numerous journal articles, he has published academic books, including "Communication through Gestures: How People Convey Intimacy," "Interpersonal Communication Aimed at Improving Social Skills," "Interpersonal Social Psychology Aimed at Happiness: Science of Interpersonal Communication and Relationships,"; and "The Psychological Strategies of Communication Design for Well-being: Optimization of Interpersonal Communication.&quot; He has also translated relevant works such as "Posture and Gesture&quot; by Bull, P.E (1987; translated in 2001), "The Social Psychology of Personal Relationships" by Ickes, W. &amp; Duck, S (2000; translated in 2004), and &quot;More than Words: The Power of Nonverbal Communication&quot; by Patterson, M. L. (2011; translated in 2013) to promote further enlightenment of the research field in the Japanese psychological community.

Abstract: Motion serves as a subtle yet impactful communicator of social cues, conveying a wealth of information beyond verbal interactions. In exploring the nuanced language of body movement, this talk outlines our institute's commitment to understanding its role in facilitating effective communication. I will introduce the development of the Diverse Bodily E-Motion Database, designed to capture emotional expressions through body movements. In addition, I examine the impact of body language on communication, how it conveys social attitudes and affects interpersonal dynamics and how it is shaped by individual differences. This talk aims to illuminate the intricate and multifaceted nature of nonverbal cues inherent in human body movements.

How Gesture Facilitates Communication

Sotaro Kita / 喜多 壮太郎

Professor of Psychology of Language

Deputy Pro Vice Chancellor (Research)
Dept. of Psychology, University of Warwick
United Kingdom (英国・ウォーリック大学) 

Abstract: When people speak, they often spontaneously produce gestures. Co-speech gestures can depict action, motion and shape as if to pantomime an action or to draw a sketch in the air; we call such gestures iconic gestures. How do co-speech iconic gestures contribute to communication? I will discuss experimental studies that indicate three ways in which co-speech iconic gestures can communicate. First, perhaps not surprisingly, iconic gestures can convey spatio-motoric contents to the recipient. Second, iconic gestures can bring the recipient's attention to a particular part of the physical context of communication, not unlike pointing gestures. Third, iconic gestures can change the recipient's impression of the gesture producer. More specifically, iconic gestures make the gesture producer look more competent and knowledgeable. Taken together, co-speech iconic gestures contribute to three important aspects of communication: contents, communication event, and sender-recipient relationship.

Bio: Sotaro Kita is Professor of Psychology of Language and Deputy Pro Vice Chancellor for Research at the University of Warwick, in the UK. After a bachelor and a master's degree in mathematical and information engineering from University of Tokyo. He obtained a PhD in linguistics and psychology from the University of Chicago, in 1993. He established and led the "Gesture Project" at Max Planck Institute for Psycholinguistics, in the Netherlands, from 1993 to 2003. Then, he held a faculty position at University of Bristol and University of Birmingham, before joining University of Warwick. He served as the President of the International Society of Gesture Studies and also as the Editor of the journal, GESTURE.
He has investigated how gesture relates to various aspects of language: motion events (Kita & Özyürek, 2003, Journal of Memory and Language) and metaphor (Argyriou, Mohr & Kita, 2017, JEP: Learning, Memory and Cognition. He has also investigated how gesture varies cross-culturally (Kita, 2009, Language and Cognitive Processes), how gesture production shapes gesturer’s conceptualization (Kita, Alibali, & Chu, 2017, Psychological Review) and how deaf Nicaraguan children turned gesture into an emerging sign language (Senghas, Kita & Özyürek, 2004, Science). 

His current research topics include how children’s word learning can be facilitated by sound symbolism and gesture, how communicative contexts influence infants’ and adults’ gesture production, and how “silent gestures” show language-like features.

Interpersonal Coordination: Now and Future

Ken Fujiwara  / 藤原 健

Assistant  Professor
Department of Psychology
National Chung Cheng University
(台湾・國立中正大学)

Abstract: Interpersonal coordination is defined as “the degree to which the behaviors in an interaction are nonrandom, patterned, or synchronized in both timing and form” (Bernieri & Rosenthal, 1991, p. 403), which is subdivided into behavioral matching, interactional synchrony, and behavioral meshing. Social psychologists who study such nonverbal behavioral patterns have suffered from the great cost of manual coding for a long time (Murphy & Hall, 2021; Murphy et al., 2015, 2019), but now benefit from automated coding techniques using computer vision and time series analysis (Fujiwara & Daibo, 2022; Fujiwara & Yokomitsu, 2021). In this talk, I will discuss recent methodological developments and future theoretical challenges in synchrony research.

Bio: Dr. Ken Fujiwara is an assistant professor in the Department of Psychology at National Chung Cheng University, Taiwan. He received his Ph.D. in Human Sciences, with an emphasis in social psychology, from Osaka University in 2013. Prior to his current position, he had worked as a lecturer at Osaka University of Economics and a visiting scholar at Arizona University and the University of California, Santa Barbara. He studies interactional or nonverbal synchrony, which has been published in communication and psychology journals such as Journal of Nonverbal Behavior, Quarterly Journal of Experimental Psychology, European Journal of Social Psychology, Communication Methods and Measures, Behavior Research Methods, and Computers in Human Behavior. He serves as an associate editor of the Journal of Nonverbal Behavior since 2022.

The Emergence of Human-Like Virtual Humans

Taku Komura  / 幸村 琢

Processor, Department of Computer Science, Faculty of Engineering,
The University of Hong Kong (香港大学)

Visiting Professor, Research Institute of Electrical Communication,
Tohoku University (東北大学 電気通信研究所)

Abstract: Human communication and interaction involve much more than just speech. Body gestures, facial expressions, locomotion, and physical contact all play a role in our daily interactions. As technology advances, it becomes increasingly possible to simulate these multimodal interactions, creating virtual humans that can behave like real humans. In this talk, we will explore the challenges of creating such virtual humans and discuss our efforts to overcome them. We will showcase our technology for synthesizing human facial expressions and body gestures from speech, as well as animating characters that can move and walk. Additionally, we will discuss the latest developments in large language models that enable virtual humans to produce realistic and creative conversations. Finally, we will delve into the potential applications of virtual humans and their transformative impact on society.

B(l)ending Realities

Frank Steinicke  / フランク・スタイニック

Professor for Human-Computer Interaction
Department of Informatics
Universität Hamburg, Germany
(独国・ハンブルク大学)

Abstract: I will discuss how the fusion of extended reality (XR) and artificial intelligence (AI) will revolutionize human-computer interaction. XR/AI technologies and methods will enable scenarios with seamless transitions, interactions and transformations between real and virtual objects along the reality-virtuality continuum indistinguishable from corresponding real-world interactions. Yet, today’s immersive technology is still decades away from the ultimate display. However, imperfections of the human perceptual, cognitive and motor system can be exploited to bend reality in such a way that compelling immersive experiences can be achieved. In my keynote, we reviewed some mixed reality illusions, which bring us closer to the ultimate blended reality space.

Abstract: User interfaces are the boundary between humans and Augmented/Virtual Reality technology. These user interfaces incorporate the visual presentation of information, virtual controls for the applications, and physical devices to enhance users' abilities to build a mental model that blends the physical world and the virtual world created for them. This is a very difficult problem to solve. Many smart scientists have investigated this problem for decades. This talk will investigate this research from the point of view of where we came from, where we are at the current moment, and possible future directions we could go. Part of this journey is a discussion of why this is a difficult problem. AR and VR user interfaces are more difficult to design than traditional 2D desktops and handheld devices.
