42.1 Introduction
Multimodal interactive simulations (MIS), also known as virtual environments, rep-
resent synthetic computer-generated environments that allow interactions by one or
more users using multiple sensory modalities, e.g., vision, hearing, touch, and smell.
The interaction may be accomplished using specialized interface devices such as the
mouse, space balls, robot arms, etc. Such simulations may be used in a variety of ap-
plications spanning video games, virtual malls, and psychomotor skill training. One
application we are interested in is using MIS to
