Gaze Control in Complex Scene Perception

Abstract

During human scene perception, visual acuity is highest at fixation and drops off precipitously and continuously with increasing visual eccentricity. The highest quality visual information is acquired from the region of the scene projecting to the fovea, a region of the retina corresponding to about the central 20 of the viewed scene. The human visual-cognitive system takes advantage of the fovea by reorienting fixation over the viewed scene an average of three times each second via saccadic eye movements. The aim of the current project was to investigate the influence of semantic factors on human gaze control during the free viewing of complex, natural scenes, focusing on the extent to which initial fixations are controlled by semantic properties of the scene.
