11. Performing a Calibration
When a calibration is performed, the participant observes a series of
calibration points sequentially displayed on the screen. The calibration
can then be validated (optional) using a similar procedure on
independent points.
11.1 Running a Calibration
When clicking Calibrate in the Calibration tab, iViewRED goes briefly
into full screen mode and a series of target shapes are displayed in
succession in each of the areas of the screen as defined by the
Calibration Method .
Calibration can be canceled at any time by using the
Esc (Escape) key.
To run a calibration:
1. Ensure the measurement values of the Laptop Display or the
Desktop Monitor are set in the Geometry tab. See Setting Geometry
Measurements.
2. Select the Calibration tab.
3. If required, set the calibration method, calibration speed, Smart
Calibration and method of accepting calibration points.
4. Click Calibrate to begin.
5. iViewRED goes into full screen mode and displays the Calibration
screen with an initial focus point in the center of the screen.
