This study analyzed visual search strategies of soccer players in one-on-one defensive situations on the field. The 8 subjects were 4 experts and 4 novices. While subjects tackled an offensive player for possession of the ball, their eye movements were measured and analyzed. Statistically significant differences between the visual search strategies of(More)
The critical flicker frequencies (CFF) were determined for various locations on the retina. Under the conditions in which pupil size varies little with target luminance and size for a retinal location, two findings were obtained. First, the relation between the CFF value and the retinal location depends basically upon the density distribution of the(More)
The purpose of this study was to clarify golfers' scanning patterns while putting through direct measurement of their eye movements. Each of the 17 subjects (3 experts, 3 intermediates, 11 beginners) performed 10 consecutive putts on a practice mat, from a position 2 m from the hole. The analysis of their eye-movements indicated differences among these(More)
A study was made on the capability to receive character information and the factors restricting it.
