Gaze Control

Playing with your eyes!

The eyes are windows to the world. People with vision primarily depend on their eyes to bring in details of the world around them. Technically, vision is also the highest bandwidth channel to the human brain, followed by hearing, touch, smell and taste. Computing technology has therefore evolved in the direction of providing very high fidelity visual experience: very high resolution displays, high update rate and so on. Sighted people interact with computing through devices like the keyboard, mouse or touch screens or increasingly with their voice. However, there is a large community of people who have very little ability to use any of these standard interaction methods: muscular impairments may prevent the use of a mouse or a keyboard. People without vision can neither use the display output nor use touch screens that depend on people recognizing the content displayed on the screen. People with nervous system impairments may not be able to accurately move the mouse or type on a keyboard or even speak.

Gaze Technologies

We believe that impairments should not keep people from engaging with the digital world. 

Fortunately, powerful technologies at affordable price points have recently become available. Eyes can now be used as the primary input mechanism to the digital world, while continuing to be the channel for absorbing visual information. These technologies are broadly called gaze-controlled interfaces. The most widely available interface is on Windows 10 computers, with an additional device called the eye-tracker, which is mounted below the screen.
