Abstract

Since the late 1960s and early 1970s researchers have been building novel display devices-- including head-mounted displays (HMDs)--and a variety of manual input devices, including force input and output. With the advent of powerful graphic workstations, and relatively inexpensive HMDs and glove-like input devices, however, interest in 'virtual environments' seems to be rising exponentially. In this paper the key components of a virtual environment-- autonomy, interaction and presence--are described. Autonomy is a qualitative measure of the capability of computational models to act and react to simulated events and stimuli. Interaction measures the degree of access to model parameters at runtime, ranging from batch processing with no interaction to comprehensive, real-time access to all model parameters. Presence is a rough measure of the number and fidelity of available sensory input and output channels. Work on representing and controlling synthetic autonomous agents for virtual environments will be briefly reviewed. Videotaped examples will be shown.
