Research on Agent-Mediated Communication:

Toward Creative Communication Systems that Demonstrate "Understanding"

Agent-Mediated Communication

In conventional research on communication systems such as groupware, it is assumed that transmission should be transpar-ent, with the intermediating devices remaining imperceptible. In contrast, our research seeks to develop an agent-oriented communication system featuring anthropomorphic self-adaptability that actively and intelligibly mediates person-to-person communication. With the proposal of novel communi-cation models and fundamental technologies, we selected and investigated the following three sub-themes: multimodal information representation and reception.


Verbal Communication Environment

In this project, we investigated the important processes of crystallization of ideas, mutual understanding, and develop-ment of thinking along with online dialog, even at the content level.

First, we proposed a way to visualize the thinking space1 as well as the idea of supporting thinking with an "outsider" agent. These proposals were based on a statistical processing of dialog utterances. Next, we proposed a group-thinking model. It models the communication process of a group of members with the processes of (i) individual thinking, (ii) idea representation and mutual exchange, and (iii) group thinking through collaborative work. An on-line discussion support system named AIDE (Augmented Informative Discussion Environment) was developed through the introduction of a formal representation of knowledge media that enables smooth exchange between processes2 . Consequently, we have confirmed the possibility of constructing a meeting agent that attends and develops dialog autonomously.


Real-world Oriented Personal Agents

We sought to develop personal agents that support person-to-person communication by linking the real world and cyber-space. These agents personally and adaptively interface with people.

First, we proposed several applications and service con-cepts of personal agents such as the ÔMeta-museum3 ' and ÔC-MAP' (Context-aware Mobile Agent Project), which are digital assistants for future museums and advanced academic conferences. We regard the exhibits and visits as the collaborative and creative processes in the Meta-museum. Through C-MAP, we have developed a personal agent that features a context-awareness capability. In C-MAP, face-to-face communication can be activated and facilitated in front of the "AgentSalon" system (Fig. 1) to which the personal agent migrates and initiates conversation according to the user's activities.

By applying C-MAP to various conferences, we have confirmed the possibility of a context-aware agent4 that activates conversation through captured information, thereby achieving agent-mediated communication.


Multimedia Communication


The third topic is to clarify the role of aesthetic and creative media such as music and video in implementing novel styles of communication. We investigated the possibility and the roles of multimedia interaction. Drawing on areas of computerized music research, we prototyped various multimedia musical instruments.

The "Iamascope5", an interactive kaleidoscope, is a multimedia instrument with which a performer can play music and create images through body movements (Fig. 2). Its natural interface and perfect sensation of immersion were welcomed at international events worldwide. The balanced interface for direct manipulation of music and images provided us with the inspiration to develop a theory of the multimedia communication model. Consequently, we proposed a multimodal communication model that links dialog, music and an embodied entity through an experimental sensor-equipped doll (Fig. 3).
