Research on Future Communications Based on Collaboration between Artists and Engineers

Our ultimate goal for art and technology is to create a new communication environment that strongly appeals to human kansei (sensitivity) by integrating different aspects of art and technology. In particular, interactive art is a new area that will enable viewers to interact with the art and achieve two-way communication. Initially, we began with the idea that collaboration between artists specializing in this new art and engineers would have great potential for this new form of communication.

Art and technology is very significant in the overall picture of our project, so each department of our lab has kept this concept in mind. We have established an independent Art & Technology Department to focus on some research themes that mainly artists will pursue. Toward this goal, we established the following three projects and engaged in relevant research:
Interactive Characters

During the first term, we proceeded with the basic concept of emotional communication. We built one system called "MIC" capable of recognizing human emotion as well as another system called "Interactive Poem1 " through which humans and computers recite poems to each other.

During the middle term, we tried to achieve deeper immersion by interacting with the systems. Specifically, we built an "Interactive Theater2 " (Fig. 1) capable of changing stories through dialogues with the characters. As an improvement, we enabled the participation of multiple individuals and added a function enabling reaction to spontaneous interaction.

In the final term of the project, we sought to create characters that can visualize the underlying meaning of superficial communication. The embodiment system, called "Unconscious Flow," is based on the concept of visualizing subconscious communication. "Neuro-Baby Internet-Mail" is another system in which characters react according to the emotional content of sentences in e-mail, and the animated characters move around. In addition, in preparation for commercial development, we succeeded in porting this new system to a PC.


Interactive Environments

During the first term of the project, we developed "MIC Space3 ," a system in which virtual plants surrounding people grow in response to the communication between the people. This is a basic system for creating an interactive environment. We also developed "Gulliver's Travels," a system that gives users the sensation of becoming a pygmy or giant.

In the middle term, our target was to enable people to feel deep immersion by interacting with the systems. We developed systems that visualize the relationship between verbal communication and non-verbal communication between people. For example, "Life Spacies4 " is an application system that converts input human messages into artificial life forms. In addition, we developed the "PICO_SCAN" system, which transforms an image of a person retrieved from a camera into an abstract computer-generated graphic. This graphic depicts one's inner feelings toward another based on the distance between them.

During the final term, we wound up our research by developing "Riding the Net" (Fig. 2), a visual communication system. Once some keywords have been uttered and the Internet has been accessed, the system retrieves images related to the keywords. Finally, the images flow onto the display. As well, we succeeded in porting this new system to a PC in preparation for commercial development.


Active Direction Engineering

We developed the basic technology for a system that elicits a sensation of immersion. During the first term, we developed a fractal structure generation algorithm that uses fractals to create high-definition images. This system effectively appeals to human kansei and comforts viewers. We also developed a technique incorporating a neural network that recognizes emotions in the voice5 . With this system, people can interact nonverbally with animated characters.

In the middle term, we focused on advancing what we had developed in the first term. Through evaluations, we confirmed that the fractal structure generation algorithm activates human brains and enhances the viewer's comfort. We also enhanced the emotion recognition method by enlarging the recognition database. Additionally, we developed an authoring tool that facilitates the generation of interactive scenes and the control of interaction.

In the final term, we sought to port the new system to a PC to make the system easier to use. We also succeeded in developing "CosTune" (Fig. 3), a wearable musical instrument as an application system.

As stated, Art & Technology is a new type of research that aims to develop innovative communication through the collaboration between artists and engineers. As a result, various types of technologies and systems have been developed. This project is now well known worldwide and has earned an excellent reputation.
