How to control your laptop with eyes

The system was invented by people from Tobi and it’s called Tobii Gaze Interface. It works by sending the user’s eyes light near-infrared region. Then, it uses two infrared cameras to capture what is reflected on the retina and cornea. With this data, it builds a 3D model of the eye. So, the system knows where the user looks, but does nothing until it has the green light. Even though it may seem difficult to use, the system is simple and fast.
