7.2.7 Customizing the Calibration Area
Customizing the calibration area can be useful if you have discovered that the user cannot access certain areas of the screen
using Gaze Interaction. By sizing the calibration area to exclude the areas that the user cannot access it can improve the overall
calibration.
To customize the calibration area, follow these steps:
1. Open Tobii Dynavox Gaze Interaction Settings > Calibration.
2. Select the Setting button.
3. Select the Calibration area: Change... button.
