From flexible, lightweight LED display solutions to sensor matrices and camera-based motion tracking, various developments lead to significant potential in the professional sports, fitness, gaming and health sectors. These technologies make it possible to gather large amounts of data on the user’s movement in real time and interact with mobile devices. In addition to targeted feedback, this also enables immersive experiences. However, current innovations only include limited visualization elements, awkward VR goggles and give almost no feedback. Moreover, most systems are extremely expensive.
