BACKGROUND: Eyes are the main gateway of visual information input. Moving the eyes is essential to extract visual information from scenes while performing motor actions. This helps to explain motor behavior, especially related to visual attention mechanisms, gaze training and learning, and the relevance of visual information in controlling actions. Thus, collecting data on gaze behavior is important for explaining motor behavior. AIM: We present the main video-based eye-tracking techniques, briefly describe the anatomy of the eyes, explain the operation of the eye-tracker (eye capture techniques, calibration, and data analysis), and propose interpretations of the main variables that were extracted by the technique. This way we develop considerations (limitations and advantages) on the eye-tracking technique that placed gaze behavior data under the view of human movement science. INTERPRETATION: Eye-tracking has become an excellent tool to assist in the analysis of human movement through gaze behavior. It is possible to make inferences, mainly from the combination of sensory information, such as visual information, with performance during motor tasks, about perception, cognition, and human behavior during the most diverse day-to-day activities. Eye-tracker systems have been employed in different majors related to motor behavior, such as medicine, commerce, and game development. [ABSTRACT FROM AUTHOR] |
