    A dynamic system for controlling the head movement and gaze of virtual characters



    Creating virtual characters with natural movements is a challenging problem. Users are very aware of how people in general move when interacting based on a lifetime of experience. Unintentionally unnatural movements can adversely affect the experience of the participant. Computationally intensive techniques for calculating dynamic movements can cause the system to run slowly, reducing the frame rate or the performance of the avatar within the simulation. Our system provides a simple implementation that enables precise individual control of multiple avatars.
