More than ten presentations at international and national conferences on physical education, sports training and performance analysis — with one question underneath all of them: how do you bring computer vision and language models onto the fencing piste without losing what a coach knows?累计进行国际及全国会议报告 10 余次，主题涵盖体育教育、运动训练与运动表现分析。所有工作指向同一个问题：如何把计算机视觉与大语言模型带上击剑剑道，而不丢失教练真正掌握的东西？
