This study introduces the design and application of an optical vision sensor device aimed at measuring motor response speed and improving shooting accuracy in handball players. The device uses advanced infrared technology to provide randomized visual stimuli, enabling an objective evaluation of shooting performance under varying conditions. Testing was conducted with handball players aged 17-18 years, comparing motor response speeds with and without visual stimuli. The results revealed a statistically significant difference, with faster response times observed without visual stimuli (mean: 0.33 seconds, SD: 0.0535) compared to conditions with visual stimuli (mean: 0.66 seconds, SD: 0.0536). The device offers several advantages, including portability, ease of use, and enhanced accuracy, making it a valuable tool for sports training and evaluation. This innovation has practical applications for sports clubs, educational institutions, and research, contributing to the advancement of training methodologies in handball.
