METHOD FOR OPERATING AN INPUT DEVICE, AND INPUT DEVICE

The invention relates to a method for operating an input device (2), particularly an input device for a motor vehicle, having a non-contact sensor (3) for capturing the position and/or change of position of at least one finger of a user's hand. An input is detected and executed on the basis of the captured position and/or change of position of the finger on an input surface. According to the invention, a virtual surface is defined as an input surface on the basis of a specifiable movement of at least one of the fingers of the hand (6). According to reciprocating movement of fingers, change quantity is changed through the input device. 本发明涉及用于运行输入设备的方法、输入设备。本发明涉及用于运行输入设备（2）、尤其机动车（1）的输入设备（2）的方法，所述输入设备（2）借助于无接触地工作的传感器（3）检测用户的手（6）的至少个手指（9、10、11、12）的位置和/或位置变化，其中根据手指（9、10、11、12）的位置和/或位置变化判定输入并且实施所述输入。在此规定，根据手指（9、10、11、12）的检测到的往复运动，通过输入设备（2）改变模拟量。
