Abstract
In recent years, a wide variety of instructional materials and applications have been developed to enhance athletes’ learning in different sports. The amount of instructional videos, in particular, has increased significantly, though these often impose a high cognitive load as users must map displayed instructions to their actions and body movements. Mobile Augmented Reality (AR) interfaces can reduce this burden by presenting instructional information directly where it is needed. This paper explores a mobile sports capture and replay approach for immersive self-training, aiming to help users improve their skills without needing coaches on-site. We investigate different capturing methods, including an Exocentric capturing method, to enhance instructor mobility and flexibility. Using the captured data, we visualize sports training instructions in an immersive 3D environment on an AR headset. We propose three visualization methods and create a first prototype that allows us to explore the approach’s feasibility across different sports.
