Since 2018, the research team from NYCU has been actively advancing badminton sports science under the Ministry of Science and Technology’s Precision Sports Science Program. Over the past seven years, the team’s research trajectory has evolved from tactical data collection and analysis of elite athletes to the development of generative AI technologies designed for broader social engagement in sports. This presentation introduces CoachAI, a pioneering system that enables shot-by-shot microscopic data labeling, facilitating fine-grained performance analysis and intelligent feedback. It also highlights the team’s recent progress in smart badminton technologies and their efforts to extend these innovations beyond professional sports. Central to this initiative is to develop a photographic 3D sensing platform for smart sports spaces, aimed at making data analysis accessible in everyday athletic environments. The overarching goal is to embed sports data science into daily life, transforming how individuals interact with and benefit from physical activity.
