Gaze Marker

• The Gaze Marker is the circular dotted marker that is displayed on the 'Record' screen of the live camera view. The Gaze Marker reflects and follows the user's eye movement, in other words, indicates what and where the user is looking.
• Gaze Marker Size and Colour can be changed to the user's preference by tapping and selecting from the options given. 
  

Recording

• Gaze Data Rate is measured in Hz. By default, a recording session will collect data with a rate of 125Hz. In other words, it will record 125 individual gaze points per second.
• When recording, a user can enable/disable camera and audio recording.
• Vergence, IPD, Per-Eye Gaze, Pupil Position, and Pupil Diameter are all individual data streams a user can select or unselect to be recorded during a session.
  

Calibration

• A 5-point calibration will be selected by default, however, a user can alter and choose how many points are calibrated: 1, 3, 5, 9, or 16 points. The more points calibrated, the more accurate the user's gaze overlay.
• Auto Calibration Points Register is selected by default and will automatically take a calibration point when the user’s gaze is oriented at the target angle. If Auto Calibration Points Register is disabled, the user will have to tap the screen for each calibration point to be taken.
  

• Gaze Depth indicates the user's gaze distance between their eyes and targeted object in meters. Please adjust the Gaze Depth to reflect the approximate depth at which the user is looking. For more information please review the article on parallax error.
