Claim 0:
1. A calibration device for use in a calibration process of an electronic display screen for touchless gesture control, the calibration device comprising:
a main body defining a main axis of the calibration device, wherein the main axis extends from a proximal end to a distal end of the main body;
a first foot at the distal end, the first foot having a footing surface being placeable on the electronic display screen such that the footing surface is in contact with and parallel to the electronic display screen, wherein the footing surface is oriented at a predetermined angle with respect to the main axis of the calibration device; and
a calibration pattern comprising a machine-readable code being detectable by one or more optical sensors, wherein the one or more optical sensors are arranged at or near the electronic display screen and are configured to observe a spatial area in front of the electronic display screen in order to detect a gesture input of a user,
wherein at least a portion of the main body is designed as a sleeve providing a receiving space along the main axis,
wherein in the receiving space, a spring is arranged which is in physical contact with a bearing part of the main body and may be elastically deformed by a rod,
wherein the rod is at least partially retained in the receiving space and slidably guided along the main axis, the rod being displaceable relative to the main body into a first and a second position,
wherein in the first position, the spring is essentially non-deformed and the rod protrudes out of the main body at the distal end.
