Eye tracking is a technology used in UX/UI design to analyze user gaze behavior on digital interfaces like websites or apps. An eye tracker captures where users look on the screen, how long they focus on certain elements, and which areas they ignore. This data provides valuable insights for optimizing design and usability: by understanding gaze patterns, designers can enhance layouts, position key content more effectively, and minimize visual distractions. The goal is to create an intuitive and efficient user experience that fosters smooth and engaging user interaction.
