A program of research to develop an Artificial Intelligence (AI) Research Test Bed has been jointly initiated by the Army Project Manager for Training Devices, the Army Human Engineering Laboratory, and the Naval Training Equipment Center's Research Department. The objectives of the program are twofold. First, it is desired to explore how to design intelligent computer assisted instruction systems to perform teaching roles now performed by humans. Second, through systematic experimental studies, it is desired to acquire the basic knowledge needed to design cost efficient training systems for future line-of-sight direct fire weapon systems. Presently, the test bed's design includes an experimental M-16A1 rifle marksmanship prototype training device and an AI training computer. The training device comprises a terrain model board; a demilitarized M-16A1 rifle instrumented to measure the shooter's aiming point, sight adjustment, and trigger control; a physiological measurement subsystem; and a microcomputer system. The training computer will be a LISP machine interfaced to the simulation microcomputer. An expert system will reside on the training computer to provide surrogate instructor functionality for the test. This paper describes the test bed with emphasis on those components nearing completion and soon to be made available for experimental use. The physiological measurement subsystem and AI training computer are currently in the design phase, and are described in functional terms only.
