Abstract

This paper suggests the method of the optotype presentation and adjustment for a computerized self visual acuity test. The proposed method is guaranteed credibility by ‘KS P ISO 8596’ in 2006. Also this system provides convenience to people who take an eyesight test based on gesture recognition of them. And the method of the optotype adjustment for a computerized self visual acuity test is able to measure objective eyesight that excluded subjective judgment of inspector and conjecture of subject’s memorization. According to result of experimental comparison between method of using real visual-acuity chart and the system of a computerized self visual acuity test, Our system showed the 98% consistency in the limit of the ±1 visual-acuity level error.
