EchoCycle was a bike-mountable prototype of an early-warning system for urban bike riders to warn them of rear traffic via wristband vibrations. It used an Arduino and 3 ultrasonic sensors to discover and notify the rider of vehicles through left and right wristbands. Left vibrations indicated a vehicle in the left rear. Right vibrations indicated the right rear. Left and right vibrations at the same time indicated a vehicle directly behind the rider.
My team at the University of Waterloo was Eric Chen, Joel Plato, Steven Yao and me.
