| Analysis of Binocular Gazing Positions |
We analyzed binocular gazing positions in the existence of a rim occlusion. When a human gaze at the rim of a textured cylinder, the gazing position shifts from the fixation target, When a human gazes at the rim of a cylinder whose upper-surface is visible, the gazing points are located at the estimated depth of surface. In this paper, to investigate the mechanism changing the gazing point, we analyzed inter-saccade intervals. The result shows that an occlusion detection mechanism exists at an early stage of human visual processing, and the mechanism causes a shorter-interval saccade when incongruity tested. We propose a saccade mechanism which includes processes for depth estimation and incongruity detection between binocular retinal images based on relationships between the gazing positions and the results of inter-saccade intervals. |
