Acoustic Beamformer

Project Description:

A computational fabric serving as an acoustic array capable of determining location and direction of motion of a vehicle while tolerating faults.

Goals:

Proof of concept, and a hardware prototype to mature our experience in the electronic textiles field. This prototype also serves as a testing and grounding application for the simulator.
