The purpose of this research is to develop a new voice-communication medium called voiscape. By this medium, two or more persons can talk each other by using a virtual sound space based on spatial sound technology. People can move freely in the "sound room" and people can choose, enter, and exit from a room. Cocktail-party like situation can be created with this medium. In short, this project targets realizing Second-Life-like world by sound.
Papers on voiscape are available here.
