标题： Investigating Encoding and Perspective for Augmented Reality

摘要： 增强现实（AR）为支持基于运动的活动，如私人训练或物理治疗，提供了有前景的机会，可以通过实时、空间定位的视觉提示来实现。 尽管许多方法利用AR来指导运动，但现有的设计指南主要关注用户视野内的简单上肢运动。 我们缺乏针对涉及不同可见性和方向的多样化场景的基于证据的设计建议。 我们进行了一项实验，以研究不同的视觉编码和视角如何影响运动指导的表现和可用性，使用了三个在可见性和运动平面方面不同的练习。 我们的研究结果揭示了不同设计在偏好和表现上的显著差异。 值得注意的是，最佳视角取决于运动的可见性，显示更多关于整体运动的信息并不一定提高运动执行效果。 我们提供了基于实证的指南，用于设计沉浸式、交互式的可视化方案，以支持更有效的AR系统。 显示英文摘要

摘要： Augmented reality (AR) offers promising opportunities to support movement-based activities, such as personal training or physical therapy, with real-time, spatially-situated visual cues. While many approaches leverage AR to guide motion, existing design guidelines focus on simple, upper-body movements within the user's field of view. We lack evidence-based design recommendations for guiding more diverse scenarios involving movements with varying levels of visibility and direction. We conducted an experiment to investigate how different visual encodings and perspectives affect motion guidance performance and usability, using three exercises that varied in visibility and planes of motion. Our findings reveal significant differences in preference and performance across designs. Notably, the best perspective varied depending on motion visibility and showing more information about the overall motion did not necessarily improve motion execution. We provide empirically-grounded guidelines for designing immersive, interactive visualizations for motion guidance to support more effective AR systems.
