TactiPlay: Multi-Granularity Tactical Parsing and Video-Anchored Match Review for Amateur Badminton Players

2026-07-29

AI Summary

This study addresses the lack of effective tools for amateur badminton players to independently extract tactical insights from match videos. The authors propose a rally-centric interactive video review system that, for the first time, integrates an expert-defined tactical taxonomy into the video replay workflow. By leveraging rally-level event parsing, precise video–data alignment, and multi-granularity structured feedback, the system enables synchronized video anchoring and court visualization. User studies demonstrate that, compared to conventional statistical reports, this approach significantly enhances the frequency, specificity, actionability, and contextual appropriateness of players’ reflective analysis, offering a novel paradigm for self-directed tactical learning in the absence of expert coaching.

Abstract

Amateur badminton players increasingly record matches, yet existing tools provide only aggregate statistics or generic summaries, leaving most unable to extract tactical insights without expert guidance. A formative study (N=8) reveals the need for multi-granularity, video-anchored tactical analysis centered on rallies. We derive a taxonomy of performance issues from national-level athletes' annotations and present TactiPlay, an interactive system that instantiates an expert-taxonomy-guided, rally-level, video-anchored review workflow. The system's analytical pipeline organizes match events into taxonomy-grounded feedback, while its interface links structured reports to rally summaries, video evidence, and court visualizations. A within-subjects study (N=16) shows that TactiPlay elicits more frequent, concrete, actionable, and appropriate reflections than a report-and-statistics baseline. These findings show how organizing reviewed match evidence into a taxonomy-guided, video-linked workflow can support amateur players' tactical reflection.
