Abstract
In accordance with whether a human operator has memorized or not the future values of system input, his pursuit tracking tasks are classified here into the precognitive pursuit tracking task and the non-precognitive one, respectively.
Under this classification, the operator's control characteristics such as the lag time, the tracking ability, the frequency characteristics and the transinformation in the precognitive pursuit tracking task are compared with those in the non-precognitive one.
The experiments are carried out as follows. In the first experiment, a human operator memorizes a certain system input by following the input at each trial repeatedly. In the second experiment, in order to examine how far the operator has memorized the system input, he recollects the memorized input without the actual observation. The operator's control characteristics in the precognitive pursuit tracking task are investigated in the last experiment, in which the operator follows again the system input with observing the actual system input, and the characteristics are compared with those in the non-precognitive one.
The results are as follows.
(1) Though a human operator has a memory limitation, he will be able to memorize the system input almost perfectly.
(2) Human operator's control characteristics in the precognitive pursuit tracking task remarkably differ from those in the non-precognitive one.
