The same model of strategy communication and visualization in AR has potentials to be implemented in other team and individual sports. Additionally, an essential part of team practice is, well... Teamwork. In the future development of ARena, we must consider the possible athlete-to-athlete and coach-to-coach interactions.
The tradeoff of designing for the forefront of developing technology is working through many technical difficulties. ARena was designed for a near future when AR technology is more refined and portable. We had to intentionally make assumptions about the technology to complete the project in time. In retrospect, we would have dedicated more time to fully understanding the technical limitations before starting.
Prototyping for a 3D space uncovered many factors that I hadn't considered while designing 2D scenes, and made me appreciate the difficulties that it presents.
