Vector Sum of Two Eyes Images Might Be an Important Cue in Human Visual System
In this paper, we inferred that vector sum of two eyes images acts as an important cue in the mechanism of human vision. In our recent report on the perceptual properties of an approaching object in periphery visual field, it was found that the perceptual performance was remarkably worse for the object moving toward the middle point of two eyes even moving distance was several times longer and it takes V curve for the orientation change. Surprisingly, when the approaching object was occluded for one eye or fell on the blind spot of one eye, visibility of an approaching object was increased even though the case when the object moving toward the middle point of two eyes; it coincided with Tylers result but that was found in central visual field. Considering these results and the several observations in connection with Tylers results, we inferred that the vector sum of two eyes image motion might be an important factor for detecting the approaching object even in fully visual field; furthermore, we inferred that vector sum of two eyes images might be one of important cues in the mechanism of human vision.
