Abstract

The goal of the research described in this paper was to study the spatio-temporal properties of visual motion mechanisms and to apply the knowledge gained to the evaluation/design of visual displays. Objective measurements of an observer’s sensitivity to the order of onset of stimuli in two-point motion sequences were obtained. The basic research findings were consistent with the idea that the spatial “grain” of the retina increases with retinal eccentricity, but that the temporal, resolving power of motion mechanisms at different retinal locations remains relatively constant. There are at least two important, applied implications of the research results. First, a visual display which is updated every 16 msec (60-Hz refresh rate), as are many raster-scan systems, will “filter out” motion information capable of being perceived by a human. Second, the critical flicker frequency (cff) is not a completely adequate criterion upon which to base the design of a display intended to simulate the motion of real-world objects.
