Claim Text:
1. An input arrangement for providing an input surface for generating at least one of a switching, a control and other input and selection signal, according to an input operation performed by a user hand, comprising: a control panel; at least one input device arranged within a detection zone and attached to the control panel thereby forming an operating element of the control panel and configured to receive the input operation wherein the at least one input device can be mechanically operated by the user hand thereby providing a haptic feedback when said input operation is performed, a field generator comprising a plurality of electrodes arranged at a distance from the at least one input device and each configured to generate an alternating electric field in the detection zone, wherein an electrical value from each electrode depends on a distance of an electrode to the input device; an evaluation circuit configured to detect the input operation by the user by analyzing changes in the alternating electric field caused by the user hand, wherein the evaluation circuit is configured to analyze the field electric changes at each electrode and to determine the location of the input device from the electrical values received from each electrode and to determine input commands corresponding to said input operation for generating said at least one of switching, control and other input and selection signal.
