Atari-HEAD stands for Atari Human Eye-Tracking and Demonstration Dataset, which is a collection of body movements and eye movements of subjects playing Atari video games. The data was collected from 4 subjects, 175 15-minute trial videos of 16 games, and a total of 2.97 million frames/demonstration. Gaze data was collected by the EyeLink 1000 eye tracker at a frequency of 1000Hz. For each game frame, the corresponding image frame, key action, reaction time to make the action, gaze position, and immediate reward returned by the environment were recorded. The subjects were amateur players familiar with these games, were only allowed to play for 15 minutes, and were required to rest for at least 15 minutes before the next trial.
