Control computer with eyes

This handout picture received from Imperial College London on July 13, 2012 shows a person demonstrating a device which enables disabled people to control a computer with their eyes at a research facility. Engineers said they had built a device using mass-produced video gaming equipment that lets disabled people control a computer with just their eyes with a price tag of under $30 (25 euros). The gadget comprises two video game console cameras, costing less than $10 apiece, attached outside the line of vision to a pair of ordinary glasses, reported the team from Imperial College London.
