This is eye tracking

Eye tracking is a sensor technology that makes it possible for a computer or other device to know where a person is looking. An eye tracker can detect the presence, attention and focus of the user. It allows for unique insights into human behavior and facilitates natural user interfaces in a broad range of devices. The ability to control a computer using the eyes is also vital for people who are unable to speak or use their hands.

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.
How a Tobii Eye tracker works

What eye tracking means for the real world

Understand human behavior

Studying eye movements provides unique insights into what really catches our attention and what information we process, which is then used to understand what affects behavior, decision-making and emotions.

Enable hands-free interaction

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

New user experiences and 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: a technology 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.

Innovation and patents are integral to the Tobii business model. 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.

Tobii’s patent portfolio includes both its core technology and various applications for its use. 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.
