A Study of Visual Context Representation and Control for Remote Sport Learning Tasks
Wanmin Wu, Zhenyu Yang, Klara Nahrstedt · 2008
Shared visual context plays a vital role in video-mediated remote learning tasks. However, it remains unclear how to provide such visual context in order to best facilitate learning. In this paper, we present an exploratory study to (a) evaluate the impact of visual context representation on sport learning in video-mediated environments, and (b) investigate how users control the visual context (e.g., changing viewpoint) in assisting learning. We find that (a) for sports, the 3D free view representation enables faster, more accurate learning than 2D representation; (b) average users tend to “browse ” randomly instead of selecting a particular viewpoint with intention; and (c) different users have dramatically different control patterns for similar visual context, which suggests the importance of user customization. We anticipate our results will bring theoretical and practical implications for the design of next-generation video-mediated learning systems.
