用第一视角视频+可视化图表，帮新手和高手提升射击训练效果。
Scope Meets Screen: Lessons Learned in Designing Composite Visualizations for Marksmanship Training Across Skill Levels
- 将第一人称射击视频叠加数据图表，生成五种复合视图。
- 9名参与者中8人偏好仪表盘式综合视图，跨水平理解力强。
- 适合射击教练、运动科学者，也适用于其他精准类运动。
射击训练广泛应用于警察、军人、猎人及奥运射击、现代五项等体育项目。当前训练以重复练习为主，教练无法直观感受射手视角，分析仅限于姿势与命中率，且多在训练结束后进行。本研究设计并评估了一套射击可视化系统，针对新手与专家射手的感知有效性展开研究。基于第一人称射击视频，融合叠加指标与图形摘要，开发了五种复合可视化界面。通过混合方法研究（含射击次数与瞄准解读任务、成对偏好比较、半结构化访谈），对10名参与者（5名专家，5名新手）进行测试。结果显示，整合原始视频、极坐标图及关键图表的仪表盘式视图，在10次评估中有9次被首选，并有效支持不同水平用户理解。研究揭示了将第一人称视频与视觉分析结合在训练指导中的潜力，为其他精密运动场景的应用提供了方向。
原文摘要 · Abstract (English)
Marksmanship practices are required in various professions, including police, military personnel, hunters, as well as sports shooters, such as Olympic shooting, biathlon, and modern pentathlon. The current form of training and coaching is mostly based on repetition, where the coach does not see through the eyes of the shooter, and analysis is limited to stance and accuracy post-session. In this study, we present a shooting visualization system and evaluate its perceived effectiveness for both novice and expert shooters. To achieve this, five composite visualizations were developed using first-person shooting video recordings enriched with overlaid metrics and graphical summaries. These views were evaluated with 10 participants (5 expert marksmen, 5 novices) through a mixed-methods study including shot-count and aiming interpretation tasks, pairwise preference comparisons, and semi-structured interviews. The results show that a dashboard-style composite view, combining raw video with a polar plot and selected graphs, was preferred in 9 of 10 cases and supported understanding across skill levels. The insights gained from this design study point to the broader value of integrating first-person video with visual analytics for coaching, and we suggest directions for applying this approach to other precision-based sports.
