This is Eye Tracking

Eye tracking is a sensor technology that enables a device to know exactly where your eyes are focused. It determines your presence, attention, focus, drowsiness, consciousness or other mental states. This information can be used to gain deep insights into consumer behavior or to design revolutionary new user interfaces across various devices. 

What eye tracking means for the real world

Understand human behavior

We take in the world around us using our eyes. Eye tracking interprets natural human behavior which helps us to gain deep insights into people's attention and actions. As a result we can also draw conclusions about the factors that drive certain behaviors.

Enable hands-free interaction

By using the eyes as a “pointer” on a screen, eye tracking facilitates interactions with computers and other devices when the user cannot or does not wish to use their hands as the input form.

New user experiences and humanized user interfaces

By combining eye tracking with other input modalities, for example keyboard, touchpad and voice, Tobii is paving the way for creating new user experiences and innovating interfaces for regular consumer devices. These will be more intuitive, natural, engaging and efficient than conventional user interfaces.

The challenge: for everyone, always.

Tobii has gradually developed a stellar technology that is number one today through relentless focus on research and development, and through building expertise in a range of specialist areas.

Our ambition is to make eye tracking a standard in computers, tablets, cars, and other everyday devices.  

To develop a simple eye tracker that works in controlled environments is not very difficult. To make a system that works for everyone, always, is enormously challenging. But for eye tracking to become a widespread technology within its respective application areas, this is a basic requirement.

Tobii's leading eye tracking technology is based on a number of innovations that make the system suited to natural human behavior and use in various environments.

Key innovation areas are:

  • optics that is unaffected by ambient light.
  • algorithms that accommodate users who move around and look different.
  • applications that create intuitive user experiences and insights.

How the eye tracker works

Three vital parts of a high-performing eye-tracking system

  • Custom-designed sensors — The hardware is designed to be a high-performance sensor, and not for taking nice pictures. It consists of custom designed projectors, customized image sensors and optics as well as custom processing with embedded algorithms.
  • Advanced algorithms — Algorithms are the brain of the system, which interprets the image stream generated by the sensors.
  • User-oriented applications — An intelligent application layer is added to enable the various ways the technology can be used.

Designed as a peripheral device, an eye tracker can be added to a regular computer screen for an easy and price-competitive way to introduce the technology in a range of usages. 

Eye tracking can be built into glasses or other wearable devices, such as Tobii Pro Glasses 2—a product for studying behavior in real-world environments.
