Tobii's Technology
Tobii’s eye tracking technology utilizes advanced image processing of a person’s face, eyes and reflections in the eyes of near-infrared reference lights to accurately estimate:
- the 3D position in space of each eye
- the precise target to which each eye gaze is directed towards
Key advantages
Tobii has taken eye tracking technology a significant step forward through a number of key innovations that enable large market applications. Key advantages of Tobii’s eye tracking technology are:
- Fully automatic eye tracking
- High tracking accuracy
- Ability to track nearly all people
- Completely non-intrusive
- Good tolerance of head-motion
Patented techniques
Compared to other technologies, a number of innovations have been made to overcome traditional problems associated with eye tracking, such as cumbersome equipment, poor tracking precision and limited tolerance to head motion. Some of the key aspects of Tobii’s technology include:
- Patented techniques to use fixed wide field of view optics in combination with high resolution sensors
- Patented techniques for accurate estimation of the 3D position in space for both eyes
- Sophisticated image processing and patented control logic to allow for 100% automatic tracking, and high tracking ability; tracks almost everyone, even those with glasses
- Advanced algorithms to compensate for head motion without loss in accuracy
- Unique techniques to enable long-lasting calibrations
Application technology
Tobii conducts research and development into eye tracking applications. We have developed an extensive toolbox of software that allows us to rapidly create eye control applications and eye gaze analysis applications.
Tobii’s eye-based interaction technology includes the Tobii eye control engine, a powerful ActiveX-based API for rapid creation of eye control applications in the Windows environment. This allows our customers and partners to quickly develop and customize applications to utilize eye gaze as a modality in computer interfaces. This is not yet on the market, but is available to key partners on a project basis.
