||InterSpace is a revolutionary communication environment that allows users the flexibility of multi-modal interaction. People in InterSpace communicate using audio as well as video interaction in a three dimensional world. Remote terimals are connected to a central server via networks. Facial image, audio, and proximity, are processed and sent out to the remote terminals to enable multi-modal communication in a virtual world. InterSpace technology comes a step closer to bridging the gap between virtual reality and world experiences. We conducted a trial service, CyberCampus, based on the InterSpace platform. Individual actions can now be shared with other users as you explore, talk, shop, learn, and experience the many facets of CyberCampus. Environments related to entertainment, distance learning, on-line shopping, and advertisement are currently being explored in CyberCampus with unlimited expansion capabilities. CyberCampus debuted in September 1995 and has been hosted by several universities and businesses in the San Francisco area. Preliminary usage suggests that multi-user, multi-modal interaction has a prominent role in the future of telecommunications.
