How do eye trackers work?
This article explains how eye tracking works. We illustrate step-by-step processes of screen-based and wearable eye trackers and XR integrations.
Get started
What is eye tracking?
Eye tracking is a sensor technology that captures and translates eye movements into insights about human behavior — its potential applications are vast.
The value of eye tracking
At it’s center, eye tracking technology measures where someone is looking. By using cameras to detect eye movements, eye tracking reveals a range of core signals including scan patterns, blinks, and pupillometry.
Eye tracking converts core signals into a data stream that can expose areas of human behavior often expressed subconsciously like decision-making, fatigue, attention, memory and much more.
How eye tracking works
Eye tracking is possible through a range of different sensor technologies: screen based, wearable, and through eye tracking integrations for devices. In each case, cameras and illuminators are used together with our advanced algorithm to provide a highly accurate gaze point.
A glimpse into the future
At Tobii, we believe eye tracking is going to help build the technological ecosystem of the future.
We imagine a world where our devices understand us, responding to our passive behavior and subconscious signals. Where our vehicles are smart and reactive third-spaces that keep us safe and comfortable on the road. Where businesses are empowered to make the right decisions with deeper insights into consumer behavior and able to train effectively by understanding their employees. And where scientific researchers make more discoveries, more often by exploring how eye movements relate to behavior, learning development, disability, disease.
The applications of eye tracking
When we understand the behavioral insights eye tracking offers, the potential applications are vast.
Academic research
Measuring attention opens a range of scientific applications – the use of specialized screen-based and wearable eye trackers to test hypotheses about behavior, development, or disease.
Commercial applications
Eye tracking helps us understand focus and awareness, providing new perspectives into training, assessment, user experience, wayfinding, and a host of other commercial applications—helping clients understand customers and employee behavior alike.
Integrations
What about devices of the future? Truly smart and interactive technology needs to understand our subconscious as well as our conscious behavior. By reading our emotional state, our energy levels, or our interest, devices with eye tracking integrations are more responsive to our actual needs in the moment.
