The eyes are the window to the soul. We can learn so much about user behavior by analyzing where people look, when, and for how long.

So, it’s no wonder that eye-tracking has become an increasingly popular research tool. Especially for marketers and UX designers, who gain valuable insights from studying the human gaze.

When combined with the Prolific platform, eye-tracking tech can be a rich source of quality data for improving user experiences.

Read on to learn more about the benefits of eye-tracking and discover some of the top tools you can use that are compatible with Prolific.

What are eye-tracking tools, and how do they work?

Eye-tracking tools are, essentially, what they say on the tin: devices that measure eye movements, viewing direction, and pupil dilation.

They help researchers understand where a person is looking and for how long, and how their eyes move between different areas.

By collecting and analyzing this data, researchers can find patterns in user behavior. These insights then help them to improve their products and services.

There are many types of eye-tracking tools available, ranging from wearable devices – like glasses or head-mounted displays – to simple cameras. (Even the humble webcam can play its part.)

Most eye trackers use infrared technology to track the user’s gaze, using reflections from the cornea and pupil to work out where they’re looking.

Why should I use them?

Eye-tracking tools can support activities across UX, marketing, psychology, and more – empowering researchers to:

Uncover user behavior

Tracking eye movements can give you insights into users’ subconscious behavior that you might not get from traditional research methods like interviews or surveys. This can help make websites easier to navigate, products simpler to use, and more.

Collect quantitative data

Eye-tracking tools provide objective, quantifiable data on user behavior, such as fixation duration, saccades (that is, rapid movement of the eyes between several points), and gaze patterns. This can be used to make fact-based decisions and support hypotheses in research.

Enhance qualitative research

When combined with other qualitative research methods, eye-tracking data can enrich our current understanding of user behavior and preferences, helping us gain a comprehensive view of people’s experiences.

Tweak studies in real-time

Some eye-tracking tools let you feed back in real-time, so you can adapt experiments based on the user’s behavior during the study.
