Abstract
There are individual differences in the degree of disorder and impairment of low-vision people, but in many cases discrimination of light and darkness is possible. Therefore, it is effective to use flashing light to support amblyopic vision. To support these low-vision people, in previous research, we conducted research on the introduction and adaptation of LEDs as support for low-vision people. Also, we are doing research to install LED blocks at the entrances to pedestrian crossings. In this research, we evaluated LED blocks laid out delineating the crosswalk entrance. The subjects evaluated the flickering stimulus intensity of the presented flickering light and the enhancement of visibility by sensory evaluation. Based on the experiment results, we consider the blinking method most suitable for amblyopia support.
