Realistic gaze behavior of CCHD characters

[iva]

Hey Frank,

I have done a lot of work with eye gaze. Do you use any eyetracking in your experiment? If yes, you can reuse participant's gaze data and modify it a little bit to animate your avatar. For example, gaze following is the most natural thing in the world, and you could make your avatar follow the participant's gaze 70% of the time, and break eye-contact for 30%, where avatar is looking at something that interests it. Otherwise, I suggest prerecording somebody's natural eyegaze and using this to animate the eyes, since except from some robotic work, nobody has really managed to program a perfect simulation of natural gazing.

And don't forget blinks! They happen every 5-10 seconds, and should last between 100 and 500 ms.
