Calibration of the mobile stand is performed similiar to the normal calibration procedure, however the markers are fixed and do not animate. Try a few calibrations using Control to get used to the calibration order, center, top right, bottom right, bottom left, then top left. When control makes a tone the calibration is complete for a point and the user should look to the next point.
The following 5 point calibration grids vary in size for various screen resolutions. Try a few to find the size that is best tracked on the display being recording (a high DPI smart phone will need a larger icon than a low resolution tablet). These calibration web pages can be found in the Gazepoint installation folder to be used offline.
