7.2.5 Removing Calibration Point(s)
If there is a calibration point that is consistently bad after calibration (the green lines are scattered all around and outside the
circle of the calibration point) you can remove that point completely from the calibration, this may improve the calibration of the
other points. Be aware that if you remove a point, that area of the screen will be uncalibrated and Gaze Interaction will not func-
tion properly there.
To remove one or more calibration points, follow these steps:
1. Open Gaze Interaction Settings > Calibration.
2. Select the point(s) you want to remove under Calibration Result.
3. Select the Remove Point(s) button.
7.2.6 Customizing the Calibration

1. Open Gaze Interaction Settings > Calibration.

General
3. Select calibration background by selecting the background color button and select the desired color.
