Differential Velocity and Time Prediction of Motion

Abstract

This investigation examined the effects of differential target velocity, horizontal or vertical plane conditions, and air traffic controller experience on the estimation accuracy of intersection time of two converging targets. Performance accuracy on this task was not significantly affected by horizontal or vertical conditions or by air traffic controllers' experience. However, accuracy in magnitude and direction varied significantly as a function of cursor speed, with slower speeds producing the poorer performance. A differential effect for various speed combinations was also noted. Estimation accuracy on the slowest cursor speed when paired with the two faster speeds was decreased while accuracy on the intermediate speed was degraded when combined with either slower or faster speeds. Estimations on the fastest speed were not affected by differential pairings.
