This innovative gadget, which consists of two game console cameras and a pair of horn-rimmed glasses, enables you to control a computer with your eyes. It was developed by scientists in London, and it’s called the GT3D. Continue reading for a video and more information.

The eye-tracking device works by first establishing where the eyes are looking, through a relatively straight-forward calibration process. The user puts on the glasses, with the two attached cameras, and stares at a computer screen full of dots. They are then told to look at different dots, with software developed by the researchers working out how the eye looks at each dot. Once calibrated, the device can be used to control a mouse on the screen and is so accurate that if you were in a normal-sized room and wearing the device it would be able to locate where you were looking to within the size of a grapefruit, say its developers.
