Eye-tracking technology is a method used to measure where a person is looking. It typically involves using cameras and sensors to detect the movement and position of the eyes. This technology can help researchers understand visual attention, such as which parts of a screen or environment attract the most focus. This technology has applications in various fields, including marketing, psychology, and human-computer interaction. For example, companies can use eye-tracking to analyze how consumers view advertisements, while psychologists may study eye movements to gain insights into cognitive processes.
