Under sponsorship of the Aero Medical Laboratory, Wright Air Development Center, the National Bureau of Standards is designing a simulator facility for research on man-machine systems. The facility is specifically intended to enable experimentation with man-machine control systems such as those for airtraffic control, ground control of interceptors, and command systems in general. The facility is to be equipped for the dynamic representation and simulation of control systems which have human operators as elements of the closed loop. The present work has included the construction of a prototype of the essential elements of a complete simulation facility. This paper presents some design considerations peculiar to this class of simulator, describes the present prototype, and indicates refinements which might profitably be incorporated in the final facility.
