Technology
Tobii develops eye tracking hardware and software used in scientific research, automotive interior sensing, healthcare, assistive technology, gaming, and extended reality (XR). Tobii's screen-based and wearable eye trackers are video-based systems. Commercial eye trackers commonly use cameras, infrared illumination, pupil-position tracking, corneal reflections, algorithms, and calibration methods to measure eye position and estimate gaze. Eye tracking data are used to study gaze behavior, visual attention, and eye movements in research and applied settings.
Tobii's eye tracking products include screen-based systems, such as the Tobii Pro Spectrum and Tobii Pro Fusion, and wearable eye tracking glasses, such as Tobii Pro Glasses 3. Tobii also provides software development kits for use with supported Tobii Pro eye trackers. Independent device evaluations commonly describe eye tracker data quality in terms of accuracy, precision, and data loss.
Research use
Vision science and behavioral research
Tobii eye trackers have been evaluated in peer-reviewed vision science and behavioral research. In a comparison of the Tobii Pro TX300 and its successor, the Tobii Pro Spectrum, De Kloe and colleagues described the TX300 as a popular eye tracker in developmental eye tracking research and reported that the Spectrum produced higher data quality, particularly for younger infants. A comparison of six wearable eye trackers, including Tobii Pro Glasses 2 and 3, found that all tested devices could record gaze during dynamic activities such as walking and jumping, while accuracy and data loss differed across devices and movement conditions.
Human-computer interaction and user experience research
Eye tracking is used in human-computer interaction and usability research, and Tobii devices are commonly used instruments in this literature. A 2023 systematic review of eye tracking in usability and user experience found that Tobii products were used in most of the studies it examined, attributing their prevalence to ease of setup, accuracy, and noninvasive operation. A systematic review of eye tracking methods in mobile and edge-computing contexts similarly listed Tobii screen-based trackers and eye tracking glasses among commonly used commercial devices.

Healthcare and medical research
Eye tracking has been studied as a noninvasive method in neurological, cognitive, and optometric research. A 2025 systematic review of eye tracking in Alzheimer's disease, mild cognitive impairment and related dementias found that antisaccade tasks consistently distinguished affected groups from healthy controls, while cautioning that most studies lacked biomarker-based diagnostic criteria; the reviewed studies used several eye tracking systems, including Tobii TX300 and Tobii Pro devices. A 2021 systematic review and meta-analysis found that eye tracking methods showed potential for evaluating cognitive disorders, while noting that protocols varied and further high-quality studies were needed. In optometry, a 2023 systematic review listed Tobii among the eye-tracker manufacturers most commonly used in the reviewed studies.
