The Playback panel is used to control the playback of the eye movement recording.




Selecting Play causes the tracker bar to automatically scroll from the beginning to the end of the recording at a rate determined by the Replay speed scroll bar.


The current playback time is shown within the Playback panel, an X cursor will move along the Horizontal eye position, Horizontal disparity and Vertical eye position traces and the current playback gaze position will be indicated on the XY panel.  The current playback position of the eyes, viewing distance, horizontal and vertical PD and head tilt will be shown in the Position panel.


The eye position at a specific time can be shown by manually moving the tracker bar to the required time.
