Calibration method for an electronic display screen for touchless gesture control

A computer-implemented method of calibrating an electronic display screen for touchless gesture control using a calibration device having a calibration pattern, wherein the method comprises:

• detecting, using at least one depth camera, the calibration pattern of the calibration device while the calibration device is placed on the electronic display screen in a calibration position;
• determining borders of the electronic display screen based at least on the detected calibration pattern, a reference pattern stored in a memory which is usable for determining an orientation of the detected calibration pattern, and screen dimension information with respect to the electronic display screen, wherein the reference pattern is a digital representation or replica of the calibration pattern, wherein the orientation of the detected calibration pattern is calculated from distortions of the captured calibration pattern compared to the stored reference pattern;
• and
• defining a touchless gesture control input area for the electronic display screen being observable by the at least one depth camera.
