How does GazeDriver work

What is eye-tracking
Eyetracking is a process in which one measures either the place being looked at or the movement of the eyes, relative to the head. An eyetracker is the machine used to measure the position and movement of the eye. Eyetracking is mostly used for research of eg usability, but has also found its way into gaming and aids. Most well-known as an aid are probably Tobii's eye-guided communication devices.

Screen versus no screen
Traditional eye control is characterized by the user looking at a screen, and the eye tracker registers where on the screen is looking, and after a suitable latency time where the user is looking at the same place, a click is performed here. This is great for communication, entertainment and whatever else you use computers for.
But mobility with eye control is a whole other world. First and foremost because eye control suffers from Midas touch syndrome.

“The most famous King Midas is popularly remembered in Greek mythology for his ability to turn everything he touched into gold. This came to be called the golden touch, or the Midas touch. According to Aristotle, legend held that Midas died of starvation as a result of his "vain prayer" for the gold touch. "

 Mobility with eye control has had the same problem as King Midas that if everything you look at can be activated, you can only keep still by closing your eyes. If you see something dangerous, you will be steered towards the danger. This was the case until we developed GazeDriver.

Screen-based mobility has another challenge, namely human vision and the way we use it. When looking at a screen, the peripheral vision is limited to the screen, and therefore the user has to constantly look away from the screen to orient himself, and thus the wheelchair stops. With GazeDriver, the user has all his vision available and can orient himself without interrupting the drive.
