A Versatile Networked Sensing System as Add-On System for Augmenting Sports Devices

In this paper, we present a novel sensing platform for training support in sports. Ubiquitous computing applications have been especially interesting for this area as sensing technologies allow unobtrusive integration and for information acquisition that formerly was not possible. The developed networked sensing system can be attached to any piece of sports equipment that either has an axis of rotation, e.g. a gear box or a belt system. We specifically target at high-priced sports equipment for sports schools and fitness studios. Here, often no integrated measurements systems are available, despite the high price of the robust machines. We present the sensor device, the overall system architecture and the algorithms to convert acceleration into Joule, a unit of great importance to trainees.
