Engineering students at Brigham Young University have developed a computer setup that can be controlled with a person's eye movements. The system measures 2 inches thick, 10 inches long and 14 inches wide, runs the Windows 7 operating system, and costs under $1,500.

The product was a result of a collaboration with Mesa, Arizona based EyeTech Digital Systems, a company that develops eye-tracking hardware and software.

Because the cost of the BYU eye-tracking computer is low compared to commercial systems that can cost upwards of $14,000, the unit can be targeted to people with disabilities in parts of the world that can't afford more expensive eye-tracking systems.
