Eye Movements and Visual Information Processing
Abstract
Eye movements are needed to acquire visual information because clear vision is available only at the center of the retina. The main objectives of the research are to understand that cognitive and sensory factors underlying the control of eye movements, and to understand how visual processing depends on the eye movements used to inspect displays. Experiments were completed shows that: (1) smooth pursuit becomes poor when the frequency of target motion exceeds 0.5 Hz even when the amplitude of motion is small (,30') so that average target velocity is low (Martins et al., 1985f); (2) the acquisition of information from visual displays is not limited by the directional pattern of saccades but is limited by size: small (<30') saccades, required to inspect small details not forming recognizable visual patterns, cannot be controlled accurately without latencies of several hundred milliseconds (Kowler and Anton, 1987).
