パーソナルコンピュータによるDVA動体視力測定法と有効性

Abstract

The measuring method of DVA (Dynamic Visual Acuity) using the personal computer was developed, and some experiments were performed, and the validity of a measuring method was investigated. The main results are as follows. 1. The result of this measuring method had very as high correlation(r=0.851) as the result of the existing measuring method (HI-10). Therefore, it was thought that it was an effective measuring method. 2. It is because the result measured by HI-10 and the result which was very alike were obtained as the reason. 1) In a schoolchild, DVA is development process and becomes a peak at the 20 years-old time. Then, it falls gradually as it grows older. 2) DVA of males were excelled than females in almost all age. 3) DVA of the vertical direction was worse than DVA of the right-and-left direction. 4) DVA of athletes were superior than nonathletes.
