"This study is aimed at the following two objectives: - To demonstrate individual differences in exercises for touching numbers on a touch panel - To demonstrate training effect of touching numbers exercises. - Seven university students( 5 males and 2 females) participated as subjects. We used a large size touch panel, 1280mm in width and 750mm in height, and sports vision measurement software (SPEESION, by Asics). The training sessions took place twice a week for 9 consecutive weeks. The main results are as follows: 1. The performances of touching numbers exercises and sports vision ability showed a correlation of r=-0.731. This indicates that the performance of touching numbers exercises can be an index of sports vision. 2. Individual differences in the performance of touching numbers exercises depend upon sports vision ability. 3. Under the conditions of this study, the training effect did not show any statistical significance. However, the task completion time was shortened for all subjects. 4. Peripheral vision significantly improved after 9 weeks of training. This demonstrates that training in touching numbers exercises expands the peripheral visual field."
