We describe a real-time animation technique to generate blinking and gaze shift, while still considering convergence, using a Graphic Workstation. Moreover, we evaluate the feeling of eye contact using this eye animation. In our experiment, we subjectively evaluate gaze generated by CG using 2-D or 3-D display, and compare it with the gaze of an actual person. We also perform an experiment on the time required for perception of eye contact when the eyes of the CG image are moving.
