An Introduction to Human Operator Simulator.
Abstract
HOS is a digital computer program designed to be used in the evaluation of complex crewstations. It enables an analyst to dynamically simulate the activities of an operator (perception, anatomy movement, decision making, etc.) and the performance of the hardware in response to the operator's actions. Like a real operator, the HOS operator must be taught how to use a system by supplying it with a description of how the equipment operates, the circumstances under which the equipment is used, and tactical strategies to be pursued in order to accomplish specific goals. The operator can then be placed in a specific tactical environment and will respond to the dynamics of the situation just as an actual operator would under similar circumstances. Models of human performance in HOS predict how long each specific operator activity will take. The HOS operator will adapt his behavior to the dynamics of the tactical situation in accordance with the rules by which he has been trained. By controlling the tactical situations, the analyst can use HOS to obtain data on human and system performance in hypothetical tactical situations-data that heretofore could only be obtained at too late a stage in the system development to have a significant impact on the system design. HOS enables different system configurations and operator strategies to be tested and studied without having to build hardware or train operators, or run actual experiments or exercises.
