Tobii Pro Glasses 2

How do the Tobii Glasses 2 work?
Eye tracking has long been known and used as a method to study the visual attention of individuals. There are several different techniques to detect and track the movements of the eyes. However, when it comes to remote, non‐intrusive eye tracking the most commonly used technique is the pupil center corneal reflection (PCCR). The basic concept is to use a light source to illuminate the eye causing highly visible reflections, and a camera to capture an image of the eye showing these reflections.
For the TobiiPro Glasses 2, there are two cameras per eye to identify the reflection of the light source on the cornea (glint) and in the pupil. What is measured eventually are fixations and saccades in milliseconds.
Combined with the measurement of the fixations and saccades, the glasses also record a video feed of what the participant is looking at, with a camera in the front of the glasses. It is also possible to use Think Aloud Protocol with the glasses thanks to the integrated microphone in the glasses.
