Using Simulation for Research - and Using Research to Develop Valid Simulation Techniques

This paper outlines the major factors involved in designing simulators that have “practical” fidelity without being overdesigned. A closed-loop logic for the development and use of simulation is set forth. The simulation approach is developed around three basic design categories -- the basic computer and servomechanism technology, the human engineering criteria, and control information. The control-information category is discussed extensively, and respresentative fixed- and moving-base research simulators in use at the Langley Research Center are presented to describe specific display designs and motion-cue effects.
