All Implemented Interfaces:

Runnable

public class GazeEmitter
extends Thread

This controller emits BML blocks with gaze behavior, to control where the VH is looking. Strategies: - look at user - don't look - look randomly around To implement these strategies, there area number of VJoints/WorldObjects: -vjRandomTarget -vjXuukTarget (moves around with user) -vjUserTarget (nonmoving version of vjXuuk -- allows us to statically gaze at the user without tracking when the user is moving around) The xuukTarget moves around all the time to reflect the position of the user's face in the camera view. while running:
