Eye Tracking Review: Importance, Tools, and Applications

Eye tracking technology has evolved as a powerful and flexible tool, providing critical insights into human visual activity and cognitive processes in a range of disciplines. This article looks at the importance of eye tracking and the hardware components used in eye tracking systems. The benefits and applications of types of eye trackers, such as remote and head-mounted, are discussed. Considerations like as spatial resolution, sample rate, and accuracy assist researchers in selecting the best equipment for their study objectives. The study discusses software essential for evaluating and interpreting data from eye movements. Then deepen on major eye movements and metrics utilized in eye tracking studies, such as fixation length, saccades, and pupil dilation. These measures offer useful insights on visual attention and cognitive processes, allowing researchers to better understand how people respond to visual stimuli. Finally, eye tracking applications in psychology, marketing, human-computer interface, and medical research are highlighted. Eye tracking demonstrates its adaptability and importance in understanding human behavior in real-world scenarios, from analyzing consumer behavior to improving user interfaces.
