The eye tracker – which consists of sensors and algorithms. The custom-designed sensors are the hardware designed to be a high-performance sensor consisting of custom components and advanced optics.
The Image-processing algorithms – the intelligence of the system, which finds specific details in the user’s eyes and reflection patterns, and interprets the image stream generated by the sensors. They calculate the user’s eyes and gaze point on a device screen.
A device or computer equipped with an eye tracker “knows” a user's intentions because what you look at is a good approximation of what you think.
It can also give indications about the person’s presence, attention, focus, drowsiness, consciousness or other mental states.
Understand users' intentions – With eye tracking the device knows where the user's focus is at any given point in time. This powerful information can be used to create much more intuitive user experiences for any computing system. It is fundamental to create truly humanized technology.
