Calibration
Calibrating the eye gaze camera helps it focus on how your eyes
move around the screen. During a calibration you will be asked to
follow targets around the screen, and the camera will score how
accurate you are in holding your gaze in each location.
In Grid 3 open Settings – Access and select Eye gaze. Use the
drop-down menu to select your camera. Choose Settings to bring
up the Calibration options.
Using the Calibration options, you can select how your target will
look, the colour of the background, and the number of points to
calibrate. You can also choose between continuous or a stepped
calibration that enables you to tap the screen to progress
between points.
Tap the Calibrate button to begin. You can cancel your
calibration by clicking the cross in the top right. Once complete
you will be given your calibration results. The camera will
remember your calibration, so you do not need to calibrate every
time you use your device. Recalibrating is recommended if there is
a change in environment or positioning.
