視線の知覚における観察距離と解像度の効果
詳細
Human performance in gaze perception was examined by using natural and low-pass filtered images presented at various viewing distances. The results indicated that there is little effect of viewing distance and cut-off frequency of the low-pass filtering. These results indicate that human gaze perception is not based on detailed information such as absolute position of pupil edge. Rather, the results suggest that gaze perception is based on position of low-frequency components relative to eye-width.
