Abstract

According to the World Health Organization, 80% of adolescents do not meet the minimum recommended levels of physical activity, a situation exacerbated by excessive screen exposure and increasingly sedentary lifestyles. This trend has contributed to a progressive decline in visuomotor skills that are essential for functional development. In response, this study presents the development of ENVISO, a low-cost bilateral visuomotor training system based on an ESP32 microcontroller, capable of generating dynamic visual stimuli and recording real-time motor responses. Its portability, modular architecture, and ergonomic interface allow for implementation in school, community, or rehabilitation settings with minimal infrastructure.A total of 26 young adults participated in an intervention using five training modes. The Timed Reaction modality, which presents random stimuli with a 750 ms response window, was identified as the most effective. After four weeks of training (two sessions per week), participants showed an average reduction of 68.16 ms in reaction time and improved neuromotor consistency, with no significant differences across body mass index groups (p = 0.169). The system provides immediate performance feedback via an integrated LCD screen, without requiring external software.
