Rapid prototyping for wearable computing

We present tools for prototyping and for testing wearable computing applications. The hardware platform consists of a mobile phone and a custom-built box, which can be equipped at runtime with different sensors and actuators. Software libraries for signal processing and classification complement the toolkit. Users without expertise in electronics or in signal processing can quickly create fully functional wearable prototypes that sense human motion and trigger tactile feedback as response to specific postures in real-time. 1
