Screen-based for the lab
For lab environments, our screen-based eye trackers, Tobii Pro Spectrum and Tobii Pro Fusion, produce visual stimuli on a screen and work together with Tobii Pro Lab to deliver insights on study participant reactions.
Clinical research
Exploring biomarkers in clinical research
There is a strong connection between deficits in eye movements and various underlying brain disorders and injuries. Clinical researchers use eye tracking to explore biomarkers for cognitive impairment, enabling new tools for diagnosis, rehabilitation, and treatment.
Types of research eye trackers
Eye trackers typically come in the form of a screen-based (embedded or externally mounted) solution, as a wearable pair of glasses, or embedded in a VR headset.
What you can measure with eye tracking
Whatever the physical form, eye tracking can deliver the information needed to:
- Measure or guide attentional processes using fixation duration and location.
- Measure the brain's ability to execute or suppress reflexive eye movements with saccade and anti-saccade tests.
- Measure a person’s ability to fixate on a moving object using smooth-pursuit tasks.
- Assess emotional responses and cognitive workload based on pupillary responses.
Fields of research
Eye tracking can measure the kinds of subtle eye movements that are linked to cognitive impairment and has become instrumental in clinical research, in areas such as:
Neurodegenerative disorders — Alzheimer’s, Parkinson’s, and Huntington’s.
Neuropsychiatric disorders — depression, anxiety, schizophrenia, and eating-disorders.
Neurological conditions — concussion, traumatic brain injury, and stroke.
Ophthalmology – visual field, lazy eye, and strabismus.
As well as dyslexia, language disabilities, and drug use.
Research setups for clinical studies
Screen-based for the field
You can connect the plug-and-play Tobii Pro Fusion eye tracker to any screen at a hospital, clinic, or research center to collect data in the field in a nonintrusive way. Works together with Tobii Pro Lab to deliver insights on behavior.
Standalone for the lab
If your study requires that patients observe or interact with physical objects or another person, you can use Tobii Pro Spectrum in standalone mode. Works together with Tobii Pro Lab to deliver insights on behavior.
Wearable for the real world
Designed for on-the-go data capture, our Tobii Pro Glasses 3 wearable eye tracker allows patients to interact and move around freely, and enables you to design studies that closely reflect real-world scenarios — for the lab and the field.

Non-invasive classification of Alzheimer’s disease using eye tracking and language
In this study, Barral and colleagues (2020) were the first to use eye tracking in combination with speech analysis with the goal of developing an accurate and non-invasive screening tool for early prediction of Alzheimer's. By coding the Cookie Theft picture into areas of interest, the researchers fused eye tracking data — fixation, saccades, and pupil size — with language data. They concluded that such an approach is promising because eye movement combined with speech data increases the likelihood of detecting at-risk individuals.
Validation of a velocity-based algorithm to quantify saccades during walking and turning in mild traumatic brain injury and healthy controls
Stuart and colleagues (2019) used Tobii's wearable eye tracking solution to measure saccadic eye movements in patients with mild traumatic brain injury (mTBI). The study participants, people with mTBI and healthy controls, carried out a series of walking and turning tests. The objective was to develop a robust algorithm to process raw mobile eye tracker data for mTBI.
Visual attention to emotional faces in adolescents with social anxiety disorder receiving cognitive behavioral therapy
Högström and colleagues (2019) investigated attention bias in young people with social anxiety disorder (SAD). They used screen-based eye tracking to measure visual attention, enabling them to compare how non-anxious and SAD adolescents react to pictures of angry, neutral, and happy faces as well as social stimuli. With this setup, the researchers could measure latency to attend and disengage from stimuli and evaluate the impact of cognitive behavioral therapy (CBT).
