An investigation was conducted of fingertip controllers which were integrated into an aircraft throttle and used in a target acquisition and tracking task. The experimental variables included two types of controllers force and displacement, and two types of output function linear and step, under three levels of gain and three levels of target speed. In the evaluation, sixteen pilots performed an aircraft control task in addition to a target tracking task in a fixed base flight simulator. Absolute pitch and roll deviations were obtained to measure aircraft control error. Measures of target tracking task performance included target acquisition time and error, time on target, X and Y axis tracking error, overshoots and control reversals. The results demonstrated that the force controller in combination with a step function was associated with a statistically significant increase in acquisition and tracking proficiency when compared to other controlleroutput function combinations.
