Stereoscopic television pursuit tracking

Abstract

This research was concerned with tracking a remote target moving in depth. A 3-D television system provided visual feedback, and direct and aided pursuit tracking systems were evaluated as a function of target speed. The stereoscopic display was shown to be generally satisfactory for remote-control operations, although some fatigue or "eyestrain" was reported, probably due to the optics of the system. Contrary to previous tracking studies on nondepth courses, it was shown that on a depth course direct tracking is consistently superior to aided tracking at the 3 target speeds used. Amplitude of error analysis provided answers concerning what Ss do when not on target. Tracking behavior was interpreted in terms of the sensory-feedback mechanisms governing the control of motor patterns. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
