What Is Eye Tracking?

Eye tracking is a technology that puts you in control of your device by using your eyes as you naturally would. 

A device or computer equipped with an eye tracker “knows” what a user is looking at. This makes it possible for users to interact with e.g. computers using their eyes.

The Essentials of Eye Tracking

The eye tracker – which consists of sensors (camera + projectors) and algorithms. The custom-designed sensors are the hardware designed to be a high-performance sensor consisting of custom components and advanced optics.

  1. Advanced micro projectors –which are used to create a reflection pattern of NIR (Near-Infrared) light on the eyes
  2. The sensors – captures high-frame-rate images of the user’s eyes and reflection patterns
  3. 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.
  4. User-oriented applications –An intelligent application layer is added to enable the various ways the technology can be used.


The Magic of Eye Tracking

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.

With eye tracking, we can humanize our technology. There're plenty of amazing new functionalities waiting just around the corner with eye tracking.

You’ll be able to point, select, zoom and do actions in faster, easier, more natural ways than you would with the mouse or touchpad - also enabling entirely new features. Your cursor is always where you need it and the whole Windows interface seems to anticipate your next action. 

It can also give indications about the person’s presence, attention, focus, drowsiness, consciousness or other mental states.


Humanized Technology

  • 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.
  • Create new user experiences and humanized user interfaces – By combining eye tracking with other input modalities, for example, keyboard, mice, joystick, touchpad and voice commands, it is possible to create more intuitive user experiences.

    These interfaces can be more natural and engaging than conventional user interfaces. Every time you click on an icon you've looked at before, if the computer knows you are looking at an icon you no longer need to grab the mouse to tell it.
