Abstract:


    Description
    The last few years have seen great maturation in the computation speed and control methods needed to portray 3D virtual humans suitable for real interactive applications. We first describe the state of the art, then focus on the particular approach taken at the University of Pennsylvania with the Jack system. Various aspects of real-time virtual humans are considered, such as appearance and motion, interactive control, autonomous action, gesture, attention, lo-comotion, and multiple individuals. The underlying architecture consists of a sense-control-act structure that permits reactive behaviors to be locally adaptive to the environment, and a PaT– Net parallel finite-state machine controller that can be used to drive virtual humans through  complex tasks. We then argue for a deep connection between language and animation and  describe current effons in linking them through two systems: the Jack Presenter and the Jack- MOO extension to lambdaMOO. Finally, we describe the initial draft of a Parameterized Action Representation for mediating between language instructions and animated actions.
