The report discusses the man-machine tracking system in terms of its elemental components from system input to system output. Forcing functions, display and control characteristics, central nervous system data processing and sensorimotor capabilities and limitations, are examined in an amount of detail suit to the problem. Relevant literature is critically reviewed and attempts are made to integrate findings, formulate explanatory concepts and hypotheses, and present design implications. Relative to the requirements of the tracking system, it is concluded that mans visual capabilities are more than adequate, motor capabilities lack thorough exploration, and that predictive behavior and reaction time lags impose severe constraints. It is further concluded that the effectiveness of the human operator could be significantly enhanced by taking advantage of his natural attributes and providing practical, cost-effective machine assists in those areas where his inputs are weakest with respect to the total system.
