The aim of this study was to analyze visual search strategies of baseball batters during the viewing period of the pitcher's motion. The 18 subjects were 9 experts and 9 novices. While subjects viewed a videotape which, from a right-handed batter's perspective, showed a pitcher throwing a series of 10 types of pitches, their eye movements were measured and(More)
The discrepancy between the actual flicker frequency and the perceived rate was investigated. We tried to quantify the subjective rate of successive visual flicker by matching it with a second stimulus, the audio flutter. The wave form of each stimulus employed in the present study was sinusoidal. The auditory stimulus employed as a reference was a pure(More)
This study analyzed the visual behaviors of soccer players while they kicked with the inside of the foot, which involved near and far aiming skills. Participants (N = 8) were required to step forward and kick a ball to hit a target. The top three scorers were defined as the High-score group, and the three low scorers were defined as the Low-score group.(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)
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 amount of information which can be perceived at a glance offers important indicators for text layout. Studies of the size of the effective visual field and average saccade length, in different languages, have clarified the visual capacity for reading. However, most of these studies examined only one language, and their results are reported as number of(More)
This study compares the visual abilities of young and elderly groups while walking, focusing on differences in the ranges and velocities of eye movements and on differences in the extent and use of their central and peripheral vision. On the basis of two experiments, the following differences between young and elderly walkers in the use of vision, as well(More)
