Augmented Reality (AR) has gained interest in various domains, including entertainment, education, and healthcare. At the crossroads of entertainment and healthcare, users involved in physical workouts may benefit from AR systems to visualize and interact with real-world blended information. On this line, we introduce M-AGEW (Magic AuGmentEd Workout), an AR system utilizing the Magic Leap 1 headset to enhance high-intensity sports activities like jogging and workouts. The system follows a data-driven client-server model, with the client as a visualization tool on the AR headset and the server handling data processing. M-AGEW overlays a dynamic virtual interface that adapts to the user’s activity, offering real-time guidance. One significant advantage is its adaptability to various AR headsets. To the best of our knowledge, M-AGEW is the first dynamic AR guidance system for outdoor running and calisthenics whose design and development process were carried out collaborating with a sports equipment company.
