Abstract: A key arrangement includes an activation element, a switch, a mechanical counterforce generating device, and a permanent magnet arrangement. The switch has at least a first state and a second state. The activation element has a basic state and an activation state and is configured to, in case of activation by a user, permit a movement from the basic state into the activation state, and in case of the movement into the activation state to permit a change in the state of the switch. The mechanical counterforce generating device is configured to generate, in case of an activation of the activation element, a first counterforce at least in certain areas. The permanent magnet arrangement is configured to generate, in case of activation of the activation element, a second counterforce at least in certain areas.

Abstract: A device for entering information includes an operating element and a control device. The device further includes an angle encoder configured to detect a rotational movement about an axis of rotation of the operating element, a touch encoder configured to detect a pressure movement of the operating element, and a transmission element configured to transmit data from the angle encoder and/or from the touch encoder to the control device. In addition, the device includes an energy transmission device configured to supply energy to the operating element via a cable-free transmission of energy.

Abstract: A touch-sensitive surface is provided on an operator control device that includes a way to detect a force applied by a user to at least one area of the touch-sensitive surface. An actuator generates haptic feedback to the user when the force applied exceeds a threshold value. An evaluation unit of the operator control device determines a time-related gradient of the force and changes the threshold value of the force according to the time-related gradient.

Abstract: A method inputs a control command for a component of a motor vehicle. The method involves generating an image sequence of an input object guided by a user in a specified detection region using an imaging device, detecting a change in position of the input object on the basis of the image sequence, and generating a control command for the component of the motor vehicle on the basis of the detected change in position. The imaging device employs at least one infrared-sensitive camera, and the detection region is illuminated using at least one infrared source.
