Height difference:
The height difference is calculated from the top of the eye tracker to the bottom of the screen.
Since the length can vary between different mobile devices you must measure the distance from the top of the mo-
bile device to the bottom of the screen value Z (as shown in the image below).
Add 30 mm (the eye tracker distance) to the measured value, ex. -value =-( Z+30).
