Development of a Reaction Time Measurement Tool Using AI-Based Skeleton Estimation for Collision Avoidance in the Visually Impaired Development of a Reaction Time Measurement Tool Using AI-Based Skeleton Estimation for Collision Avoidance in the Visually Impaired Akira, Kimura Akira, Kimura セッション4 This study developed an AI-based skeleton estimation program to help visually impaired individuals avoid collisions by providing adequate reaction time. To evaluate the device's effectiveness, baseline reaction times were measured via stimulus-response tasks. Ten visually impaired participants from Gunma Prefecture responded to a recruitment notice and participated in the study. Key measurements included the time from electrical stimulation to collision avoidance reaction and the time to return to an initial posture. A Python-based program was used to process video data, extract coordinates, and record response times. Results showed that, upon detecting an approaching person at a 2-meter distance, the average reaction time was 1.6(0.8) seconds, and the time for posture recovery was 2.8(2.7) seconds. These findings suggest that AI-based skeleton estimation can support future development of safety devices, enhancing independence for visually impaired individuals in real-world settings.
