A position detection system (1) comprises a proximity sensor device (3) which is configured to detect at least one position of an object (F) approaching towards at least one input device (20), and a calibration device (4) which is configured to calibrate the proximity sensor device (3) with respect to a position detection and comprises a terminal (40) for coupling to the at least one input device (20). The calibration device (4) is configured to repeatedly receive from the at least one input device (20) position signals (SP1, SP2, SPn) over at least a period of time during normal operation of the input device (20), wherein each of the position signals (SP1, SP2, SPn) contains information regarding a respective position of an object (F) touching the at least one input device (20). The calibration device (4) then repeatedly calibrates the proximity sensor device (3) with respect to position detection upon receiving of a respective one of the position signals (SP1, SP2, SPn). |
