In a teleconferencing system with realistic sensations, human images a
re generated by computer graphics (CG). This requires animating natura
l eye movement with CG. This paper describes a real-time animation tec
hnique to generate blinking and gaze shift, while still considering co
nvergence using a graphic workstation. Moreover, the feeling of eye co
ntact is evaluated using this animation. In this experiment, the gaze
generated by CG using two-dimensional (2-D) or 3-D display is evaluate
d subjectively and compared with the gaze of an actual person. Also, a
n experiment is performed on the time required for perception of eye c
ontact when the eyes of the CG image are moving. Then, a real-time CG
eye-animation system combined with an eye-movement detector is describ
ed. Also, the allowable transmission delay time when using this system
is evaluated subjectively.
