Example: while driving

A live running camera captures a ‘scene video’, encompassing the surroundings as the user sees it.

Simultaneously, an ‘eye pupil video’ is unobtrusively being captured by Locarna’s glasses, without interfering with the users ability to drive.

These videos are subsequently merged to create an incredibly accurate tracking video of the driver’s visual attention.

The merged video is played back in real time, following the exact movements of the drivers eyes at any given moment.

What is Eye Tracking?

An eye tracker is a tool for measuring where a person looks. Eye tracking typically involves two video cameras. One camera views a person’s eye pupil movement, and a second camera views a real world scene.

Eye tracking technology processes the eye camera and scene camera videos into a single eye tracking video. These eye tracking videos and data create value by suggesting opportunities to improve efficiency and safety.

Eye tracking terms

Eye gaze

The spatial location of where a person is viewing. For example, one’s eye gaze may scan the print of a book.

Visual fixation

The act of maintaining eye gaze on a particular spatial location for an extended period of time. Visual fixations are typically between 100 - 500 ms long and indicate conscious attention to the location. For example, an automobile driver may visually fixate on a stop sign (more...).
