Abstract
The effects of an aural display in a compensatory tracking task are studied as compared with a visual display. The aural display system consists of a stereoheadphone and a FM-convertor, which indicates the magnitude of tracking error with the tone pitch and the polarity by switching the tone between the left and the right earphone. The root-mean-squres and the describing functions of the input and the tracking error are measured in different conditions. In this measurement, a simple fourier analysis technique is applied using an analog-computer. As the results of this paper, an evaluation of human operator control characteristics for aural compensatory tracking tasks is presented.
