Fixation Detector
Neon Player runs the same Fixation Detector employed in Pupil Cloud. It calculates fixations for the whole recording. The menu gives feedback about the progress of the detection, how many fixations were found, and shows detailed information about the current fixation.
The Show fixations toggle enables or disables visualization of fixations. You can modify the appearance of the fixations in the menu. The blue number next to the fixation circle corresponds to the fixation ID.
Press f or click the arrow buttons on the left-hand side of the window to seek forward or backward through fixations.
