a Prosaccade task. Each trial began with a central fixation for 800 ms, after which the target appeared at a random location and remained for 1000 ms. Participants were asked to saccade to the target as soon as it appeared. b Saccade latency distribution for the prosaccade task. c Smooth pursuit task. Participants were asked to look at the green dot as it moved along a circle. d Sample scanpath from a single user shown in black (ground truth in green). e Population-level heatmap from all users and trials.
