1. EOG: Build an electrooculograph eye motion sensor to control a device. Patients with, for example, ALS cannot control their arm muscles precisely making it hard to steer a wheelchair, or control a PC mouse. The students develop their own hardware to measure the bio-potential present around the eye, decide how to translate the analog signal to digital, design a smart algorithm to recognise looking left, right, up and down, and, finally, design a game where a wheelchair moves through a maze, controlled by these eye movements.
