Our Technology

Tobii has revolutionized the field of eye tracking technology by developing eye trackers that work for basically any user without requiring any manual adjustments. Our eye trackers combine excellent accuracy and precision with an extremely high tolerance for large head movements and a variety of environments.

Our aim and promise is to develop eye trackers that are:

Accurate and precise to ensure researchers get the most reliable research results
Unrestrained and unobtrusive so researchers can capture natural human behavior
Capable of robust tracking so researchers can work efficiently with a wide cross section of the population
Easy to use and automatic so a variety of researchers can use the technology without needing extensive training and get results within a short time frame

Perfecting core technology

Perfecting eye tracking technology to function automatically and be accurate and precise for all types of people and all types of conditions, even during large user movements, is an extremely tough challenge.

Every year Tobii invests a considerable proportion of its revenue in research and development, most of which is earmarked for eye tracking technology and product development. Our R&D staff has 80 engineers, ten percent of whom have a PhD. The team comprises some of the world's leading experts in optronics, image processing, mathematics, programming, and, of course, eye tracking (eye tracking technology and applied eye tracking).

Unique technological innovations

A number of clearly distinguishable technological innovations contribute to the superior performance of our eye trackers. Below are a few:

TrueEye. Creates a unique physiological 3D model of each individual's eyes. Enables much more accurate compensation for head movements and pupil drift than any other product on the market.
Dual- sensor technology. "3D vision" using double-image sensors enables a truly accurate measurement of the distance from the sensor to the user's eyes. Improves accuracy, precision, tracking robustness and contributes to the TrueEye model.
High- quality sensors. High resolution of each eye is critical to reduce noise and obtain good precision. High sensitivity is a prerequisite for a large track box.
Precise sensor control. Contributes to high sampling rates, gives perfectly consistent sampling rates and an accurate timestamp of each data point.
Embedded processing. The eye tracker has its own dedicated processor and operating system integrated into the system. Because the system runs completely independent of computers and other software, it is independent from, for instance, Windows upgrades.

Patents and technology innovations

Tobii has an extensive patent portfolio to protect its unique proprietary technologies. These patents and patent applications cover aspects such as sensor technology, illumination methods, data transfer mechanisms and eye control interaction techniques.
