An Experimental Investigation of Two Linear Rate-Field Displays.
Abstract
An airspeed display and a lateral displacement (runway) display, arranged vertically and horizontally, respectively, were concurrently tracked by relatively inexperienced pilots using a joy stick. On each display the primary indication was a small band which moved lengthwise. A moire-pattern rate field (RF) moved alongside and with the primary. Each of four experimental conditions included the primary and (a) no RFs, (b) the airspeed RF only, (c) the runway RF only, or (d) both RFs. Response measures for each display include (a) root mean square (RMS) tracking error, (b) latency of initial response, and (c) control reversals. RFs decreased RMS error for the runway display. Latency was faster, and more reversals occurred on the airspeed display than on the runway display. RFs apparently serve an attention gathering function, but this cannot be fully investigated until optimum direction-of-motion relations are determined. (Author)
