What RealEye is

A research platform that turns an ordinary webcam into an eye tracker. Participants join from their own laptop, the browser runs a neural network that detects face and pupils and predicts where they are looking, and gaze data comes back for analysis.

It removes the laboratory from eye-tracking studies, which changes who can run them.

What you can do with it

• Create a study in the browser
• Gather data from remote participants
• Analyse gaze data after the session
• Test websites, mockups and video advertisements
• Use your own participants or a panel
• Collect basic facial coding for video testing

Who it is for

• UX researchers without lab equipment
• Universities and academic researchers
• Agencies testing advertising creative
• Product teams studying page layout

What to watch out for

• Webcam accuracy is lower than laboratory hardware: the stated figure is around 110 px, which suits page-level questions and not fine detail
• Participants need a webcam and a modern browser, which biases who can take part
• Recording faces and gaze is biometric-adjacent data, so consent and retention matter
• Lighting, webcam quality and participant movement all affect results
