AR与图像、视频在运动学习中的比较研究
Comparative Study of AR Versus Image and Video for Exercise Learning
摘要：
在健身中使用移动增强现实（AR）的关注不够，尽管移动AR易于使用，不需要额外的成本，并且可以成为强大的学习工具。在这项工作中，我们提出了一个移动AR应用程序，可以帮助用户学习练习与虚拟私人教练。我们进行了一项有10名参与者的用户研究，以调查ARFit的学习质量（即，所提出的移动AR应用）与传统方法（例如基于图像的学习和基于视频的学习）相比。我们的研究结果表明，参与者使用移动AR进行运动的学习质量高于（1）在所有选定的运动中进行基于图像的学习，以及（2）需要更多空间知识的基于视频的运动学习，并由合格的私人教练进行评估。此外，ARFit在可用性方面的评级极佳，被认为是高度可接受的，是大多数参与者（N=9）首选的运动学习方法。
英文摘要：
There is inadequate attention to using mobile Augmented Reality (AR) in fitness, despite mobile AR being easy to use, requiring no extra cost, and can be a powerful learning tool. In this work, we present a mobile AR application that can help users learn exercises with a virtual personal trainer. We conduct a user study with 10 participants to investigate the learning quality of the ARFit (i.e., the proposed mobile AR application) in comparison to traditional methods such as Image-based learning and Video-based learning. Our results indicate that participants have a higher learning quality of exercise with mobile AR than (1) Image-based learning among all exercises selected and (2) video-based learning with exercise that requires greater spatial knowledge, with the performance evaluated by a qualified personal trainer. In addition, ARFit has an excellent rating in usability, is deemed to be highly acceptable, and is the preferred exercise learning method by most participants (N=9)
