This paper reports on the evaluation of the concept of interactive camera-based coaching and training (iCaCoT), which focuses on using interactive video navigation for coaching and training purposes. The iCaCoT concept leverages tiled streaming technology, which allows users to navigate freely through high-resolution video feeds while minimising the bandwidth required, by only streaming the part of the video the user is interested in. iCaCoT gives a trainer the possibility to zoom in on her trainee while she is training and to focus on specific areas, both spatially and temporally. This concept becomes especially useful for training activities where the exact line followed by the trainee is not known beforehand (e.g. skiing, footballing), and thus where capturing the events using a static wide-angle camera located relatively far from action may be more convenient than a moveable close-up camera. We implemented the iCaCoT concept as an iPad application and demonstrated it with ski athletes in the popular ski location of Schladming, Austria. Our experiment shows that iCaCoT is a viable concept for ski training activities and that it gives interesting insights for future research directions.
