Christian, Andrew; Healey, Jennifer

HPL-2005-188

Keyword(s): accelerometers; 802.15.4; zigbee; wearable; motion; sensor; activity; wellness

Abstract: On-body sensor wireless sensor networks using standard TCP/IP protocols allows a system to be built that is both convenient and manageable. We describe a set of 10 gram two-axis accelerometers running SIP-based streaming media servers and a lightweight data aggregator. Motion capture data is analyzed for type of motion and stored in annotated form for later analysis for medical applications.
