Eye Tracker Definition

An eye tracker is a device or system that measures where and how eyes move. It uses infrared light and cameras to monitor eye position and movement, enabling the study of gaze patterns and attention. Eye tracking technology is employed in research, healthcare, marketing, and gaming to understand user behavior and interactions.

Eye Tracker Explained Easy

Imagine a magic pair of glasses that knows where you're looking. An eye tracker works like that—it watches your eyes closely to see what grabs your attention or where you focus on a screen. It's like a detective solving the mystery of your gaze.

Eye Tracker Origin

Eye tracking began in the early 20th century with mechanical devices that recorded eye movements. The technology has since evolved, incorporating infrared cameras and software for precise and non-intrusive tracking.

Eye Tracker Etymology

Derived from "eye," referring to the organ of sight, and "tracker," meaning a device that monitors or records movement.

Eye Tracker Usage Trends

Eye tracking has surged in popularity due to advancements in artificial intelligence and hardware miniaturization. It is commonly used in user experience (UX) testing, gaming, medical diagnostics, and advertising. Businesses leverage eye tracking to optimize designs and better understand customer behavior.
