Transforming healthcare and accessibility through innovation

Imagine being able to spot early signs of Alzheimer’s without speaking a word or helping someone with ALS communicate using their eyes. This illustrates the power of eye tracking technology, which is quickly changing how we approach healthcare and accessibility. 

Once limited to research labs, eye tracking has entered clinics, rehabilitation centers, and homes. It provides non-invasive, real-time insights into cognition, emotion, and behavior. Whether you're a clinician, caregiver, or innovator, this technology creates new opportunities for personalized care, early diagnosis, and inclusive design.

What is eye tracking? 

At its core, eye tracking measures where and how people look.

It uses infrared sensors and cameras to capture: 

• Fixations – where the gaze lingers. 

• Saccades – rapid eye movements between points. 

• Pupil size – linked to cognitive load and emotional state. 

• Blink rate – often tied to fatigue or neurological function. 

In healthcare, these subtle signals can speak volumes, especially when patients can’t. 

Eye tracking in diagnostics 

Eye movements are closely linked to brain function.

That’s why clinicians use eye tracking to detect and monitor: 

• Alzheimer’s and dementia: Slower gaze transitions may signal cognitive decline. 

• Autism spectrum disorder (ASD):  Atypical gaze patterns help with early diagnosis. 

• Parkinson’s disease: Eye irregularities often appear before motor symptoms.

• Concussions: Gaze tracking helps assess focus and reaction time post-injury. 

Because it doesn’t depend on speech or mobility, eye tracking is beneficial in pediatric and geriatric care. 

Monitoring fatigue and cognitive load 

In high-pressure settings like surgery or intensive care, mental fatigue can be risky.

Eye tracking helps: 

• Detect when clinicians are overloaded.

• Monitor attention during long shifts.

• Improve training by analyzing gaze during simulations.

Some systems even provide real-time alerts when cognitive load goes beyond safe limits. 

Supporting mental health 

Eye tracking is also making strides in psychiatry: 

• Depression – Reduced eye movement or gaze aversion. 

• Anxiety – Hyper-scanning behavior.

• Schizophrenia – Disorganized gaze patterns. 

These insights enhance traditional assessments, providing a more complete view of mental health. 
 

Eye tracking and accessibility 

For individuals with physical or cognitive challenges, eye tracking is a game-changer.
People with ALS, cerebral palsy, or spinal injuries can use eye-gaze keyboards to type, speak, and control devices, thereby communicating with their environment. Companies like Tobii Dynavox are leading the way in AAC (Augmentative and Alternative Communication) by leveraging Tobii's eye tracking technology to enable gaze-based interaction. 

Interfaces for low vision 

Eye tracking helps adapt digital interfaces in real time, offering: 

• Magnification 

• Audio feedback 

• Highlighting of gaze targets 

This makes technology more inclusive for users with partial vision loss. 

Supporting neurodivergent users 

For those with ADHD, autism, or learning disabilities, eye tracking helps: 

• Identify attention barriers.

• Adjust content pacing and layout.

• Empower educators with personalized attention maps.

These insights are shaping more responsive learning and therapy tools. 

The future is intelligent and inclusive 

Looking ahead, eye tracking is likely to play a growing role in emerging healthcare technologies. These developments could open up new ways to understand patients and users in real-time.

For example: 

• Glasses that help indicate cognitive strain or fatigue. 

• VR therapy environments that adapt based on emotional or attentional cues. 

• Remote care models that assess engagement without relying on verbal input. 

Taken together, these directions suggest that eye movements may become a meaningful indicator of health, capability, and opportunity as the technology continues to mature. 

Tobii supports healthcare innovation 

At Tobii, we want eye tracking to support healthcare professionals, not add complexity. Solutions such as Tobii wearable eye trackers, Tobii Pro Fusion, and Tobii Pro Lab provide reliable, real-time insights across clinical practice, research, and assistive applications. From diagnosing neurological conditions to supporting therapy and enabling communication for nonverbal users, Tobii’s technology reveals critical information that might otherwise go unseen.

We collaborate with clinicians, researchers, and accessibility advocates to develop care that is more responsive, inclusive, and centered on human needs.
