Gaze Tracking
Definition
Gaze tracking, also known as eye tracking, refers to a set of technologies that measure where a person is looking. This technique captures the point of gaze and the motion of the eyes, enabling researchers and designers to gather insights into user behavior and attention. In UX design, gaze tracking is essential because it helps professionals understand how users interact with interfaces, identify areas of interest, and optimize layouts for enhanced user experience.
Importance in UX cannot be overstated; it provides invaluable data about user interactions with digital products. By understanding which elements attract attention and which are overlooked, designers can make informed decisions that lead to more intuitive and engaging designs. Gaze tracking can be performed using various methods, from remote cameras to wearable eye-tracking devices, each offering different levels of precision and application.
Key concepts in gaze tracking include fixation, saccade, and heatmaps. Fixation refers to the point where the gaze remains stationary, while saccades are the rapid movements of the eyes between fixations. Heatmaps visually represent areas of focus on a screen, indicating where users are most engaged. By analyzing these elements, UX professionals can refine their designs to align better with user attention pathways.
Expanded Definition
The history of gaze tracking can be traced back to the early 20th century, with the development of various eye-tracking devices. Over the years, the technology has evolved significantly, transitioning from cumbersome setups to sophisticated software and hardware solutions that are now accessible to UX professionals. Modern gaze tracking systems use advanced algorithms and machine learning to improve accuracy and usability.
Related concepts include user testing and A/B testing, where gaze tracking can enhance the understanding of how design changes impact user behavior. By integrating gaze tracking with other research methods, UX designers can achieve a holistic view of user interaction, leading to more effective design decisions.
Key Activities

Example
A well-known application of gaze tracking is in the field of advertising. Companies utilize gaze tracking to determine which parts of an advertisement attract the most attention. For instance, a clothing brand might analyze how users view their online ads and adjust the placement of the product images to maximize visibility and engagement based on the collected gaze data.
Use Cases
Website optimization to improve user engagement and conversion rates.
Game design to understand player focus and enhance gameplay mechanics.
Advertising and marketing research to refine visual content and placements.
User testing for software applications to detect usability issues.
Accessibility studies to assess how users with disabilities interact with interfaces.
Challenges & Limitations
Potential privacy concerns associated with tracking user gaze.
Variability in individual eye movement patterns making data interpretation complex.
The need for specialized equipment which may be cost-prohibitive.
Environmental factors, such as lighting and screen glare, can affect accuracy.
