Virtual Reality Applications and Impacts

The possibility of natural interaction within a Virtual Environment is one of the most potentiating aspects of VR in the on-going evolution of the man/machine interface. In simulation applications, where some aspect of the real world is artificially recreated, more or less natural dexterous interaction is available by means of instrumented gloves (direct manipulation of virtual objects replaces the abstraction of interaction via keyboards and text commands). In scientific visualization applications, however, we face a conundrum in trying to provide a more natural interface to highly abstract data. Although scientists and engineers develop perspective and intuition through their real world experiences, few have had any visceral or physical experience that maps naturally to the mathematical manipulation of unseen forces--for scientists and engineers instrumentation is often the natural interface. To provide an effective interface for these applications, we have developed a Virtual Instrument that can replace the glove. This VI is loosely based on the Virtual Tricorder concept that was developed by Henry Sowizral of Boeing. A prototype Virtual Instrument was successfully demonstrated by Sterling at NASA Goddard Space Flight Center.
