Project

Wearable, Wireless Sensor System for Sports Medicine and Interactive Media

Groups

This project is a system of compact, wearable, wireless sensor nodes, equipped with full six-degree-of-freedom inertial measurement units and node-to-node capacitive proximity sensing. A high-bandwidth, channel-shared RF protocol has been developed to acquire data from many (e.g., 25) of these sensors at 100 Hz full-state update rates, and software is being developed to fuse this data into a compact set of descriptive parameters in real time. A base station and central computer clock the network and process received data. We aim to capture and analyze the physical movements of multiple people in real time, using unobtrusive sensors worn on the body. Applications abound in biomotion analysis, sports medicine, health monitoring, interactive exercise, immersive gaming, and interactive dance ensemble performance.
