Using Low-Power Sensors to Enhance Interaction on Wristwatches and Bracelets

In the last few years, new interactive wristwatches are available on the market. Despite their impressive hardware capacities, the interaction on such devices remains rather limited. We propose a cheap and low power consuming way to enhance interaction on a wristwatch but adding position sensors on the watchband. We then present a MP3 player application as a proof of concept for our prototype.
