EYE TRACKING EXPLAINED
How and why electronic devices employ technology to follow a user’s line of sight
WORDS SCOTT DUTFIELD
Eye tracking is a combination of sensory hardware and analytical software that pinpoints and tracks the movement of a person’s eyes. This has been around since the early 1900s, when psychologist Edmund Burke Huey created a contact lens with a needle attached to help assess the fluency of a person’s reading ability. Since then, the modern era of eye tracking technology has digitally evolved beyond the need for uncomfortable contacts.
