Abstract
Sport spectating and training has changed substantially in recent years. Nowadays match and training-related data are getting captured in huge quantities and qualities. With this increase of available data, there is also a strong need for novel user interfaces and new visualization techniques to present meaningful information. Broadcast media and online content are often used for remote spectating. However, they are not well integrated into the actual events during the sports performance, e.g., a live game. The same is the case for video analysis software that is often used for retrospective analyses of training sessions. Augmented Reality (AR) is an interface that focuses on in-situ visualization and comes with the advantage that it integrates the content directly into the field of view of the observer (spectator, coach, manager) which could be beneficial for live events and situations. In this chapter, we will discuss the potential of AR for sports spectating and coaching.
