Abstract:

This report reviews factors contributing to the effects of lags in head-coupled systems. A model of head tracking behavior is defined with appropriate feedback loops. The relevant lags and their possible effects on operator performance are defined. Twenty-one head-coupled simulators and operational head-coupled airborne systems are listed and grouped according to their feedback loops. Studies of the effects of lags within individual feedback loops are reviewed. The feedback loops investigated were the head-coupled visual loop, the head-slaved weapon control loop, the manual control loop, the eye- coupled visual loop, and the eye-slaved weapon control loop. The effects of relevant task and simulator variables, such as target velocity and motion cues are also discussed.
