Development of Motion Comparison System Using MediaPipe to Promote the Acquisition of Diving Skills

Abstract

In recent years, the percentage of deaths and missing persons due to diving accidents has been increasing in Okinawa Prefecture, with drowning accounting for 70% of the deaths. Therefore, we developed a motion analysis system that to understand the differences in posture between students and instructors to acquire to determine their diving skills. We verified the posture improvement in the group using this system and the group receiving conventional diving instruction, as well as the posture improvement before and after the use of this system. We found that the system had a significant effect on posture improvement. It also promoted an autonomous learning attitude toward skill improvement.
