RATE DISCRIMINATION AND CONTROL IN A MULTIPLE TRACKING TASK
Abstract
The study reported here is concerned with encoding rate information and the measurement of the helicopter pilot's ability to discriminate and control such information when the information is encoded in a manner more analogous to real world visual conditions than the traditional symbolic dial and pointer. At the same time the operator was required to perform a tracking task analogous to the tracking requirement placed upon him in maintaining the spatial position of his vehicle during an approach to landing. Within the limitations of available experimental equipment symbols were generated which were analogs of real world forms and which c anged their size in accordance with the apparent size changes of the real world forms as they were approached. The study compared performance of a contracting circle encoding rate, with performance of a line expanding from the center of the display to the top and with a line expanding from the bottom of the display to the center, while keeping an aircraft symbol in the center of an inscribed circle. Twenty-four flight naive people from the Engineering Department and twelve experienced helicopter pilots were given sixteen trials on each of the symbols; forty-eight in all. (Author)
