Abstract
We have developed a face model creation system for expression of persons in 3-D virtual space communication system. The system realizes robust image process in background and illuminance condition for input face image. We compared 3-D facial expression in virtual space with the system with 2-D facial expression in virtual space and face-to-face meeting. We measured that contribution of facial information in an encounter process in communication. As the result of analysis, we found effectiveness of 3-D facial expression in distance and angle at the finding a target person, and time to find the one compared with 2-D facial expression. But it was inferior to face-to-face meeting. Based on the result, we discuss the necessity of the system to be used for the communication system.
