A study on the effects of the uncertainty of objectives-presentation in the manual tracking task

An experimental study was made to examine the effects of the uncertainty of objectives-presentation using two-handle and joystick on the predictive, precognitive and preview manual tracking systems (pursuit tracking system). The task had two factors of difficulty, a locational and a temporal uncertainty, chosen to be perceptibly more difficult having a high presentation rate. Six male subjects were required to perform the experiments. It was obtained from the results of the experiments that the preview manual tracking system is better than the other systems and the performance decrement doesn't appear.
