method of operating input device, input device, and motor vehicle

The invention provides a method of operating an input device, input device, and motor vehicle. The invention relates to a method for operating the input device, in particular of the motor vehicle which comprises at least one contactlessly operating sensor for detecting a position and/or position change of at least one finger of a hand, and a display unit (4) for displaying information, wherein the input is judged in dependence of a detected position and/or position change and the input is executed. It is envisaged that when a ring formed through the finger (8) is detected by the sensor (3), according to a change of the distance of the finger (8) to the sensor (3) and/or to the display unit (4), the presentation of the display unit (4) information displayed is changed. 本发明涉及用于运行输入设备的方法、输入设备、机动车。本发明涉及一种用于运行输入设备（2）、尤其是机动车（1）的输入设备（2）的方法，所述输入设备（2）具有至少一个用于检测用户的手（6）的至少一根手指（8）的位置和/或位置变化的非接触式地进行工作的传感器（3）并且具有用于显示信息的显示单元（4），其中根据所检测到的位置和/或位置变化判定输入并且实施所述输入。设置的是，如果通过所述手指（8）形成的环被所述传感器（3）检测到，那么根据所述手指（8）到所述传感器（3）和/或到所述显示单元（4）
