Overview

We are investigating and developing prototypes for personal activity monitoring and health applications. A typical solution involves the use of a PDA or "smartphone" as a local hub serving a set of body-worn sensors. We have successfully instrumented individuals with accelerometers, gyroscopes, GPS, and cameras for the purpose of supporting activity monitoring. The sensors, computers in their own right, serve as the sensing tier in an overall system. The PDA aggregates data in a local control loop and serves to relay data via wifi or mobile carrier to a database in the internet cloud to be served up for analysis or maintining a personalized view of activities. This model has been replicated in three projects. Results will appear pending release.
