The invention relates to an input device comprising capacitive detection device having detection surface including first array of array electrodes; electronic evaluation unit electrically connected to array electrodes to form associated electric measuring field array for spatially resolving detection of capacitive influence on detection surface; handling means disposed on detection surface to be movable along an adjustment path parallel to detection surface, in order to perform an operating input; position indicator; and coupling device with a first surface on which a second array of coupling electrodes is formed, and with a second surface on which a third array including spaced-apart contact surfaces is formed. Based on the position of the handling means, contact surfaces are touch-contacted by the position indicator. The coupling device includes several electrically conductive connections to capacitively influence the measuring field array. The electronic evaluation unit is configured to detect position-dependent influence on measuring field array.

Input device having a movable handle on a capacitive detection surface and having capacitive coupling apparatuses

A rotary knob having (inter alia, adjustable) a coupling electrode and capacitive coupling devices for placing on a touch screen is provided. Depending on the position of the rotary knob or of the coupling electrode, contact of a corresponding partial region of the touchscreen is detected. The rotary knob is designed detect and ignore disturbing influences such as drops of water.

The present disclosure relates to an operating assembly consisting of a carrier, an actuating element that is mounted movably relative to the carrier and so as to return into a rest position and which defines an input surface and has a detector for detecting a touch occurring on the input surface, and of at least one rotary adjuster, which is disposed on the input surface and is mounted rotatably relative to the input surface, and of a matrix of force sensors between the carrier and the actuating element, and of an evaluator, which is configured for carrying out a positional determination of a touch that has occurred on the input surface from the signal obtained by the detector, and for identifying at least one action of the actuating force on the rotary adjuster based on the signals of the matrix of force sensors by a comparison with predetermined values.

Control arrangement consisting of an actuating element with an input surface and rotary actuator arranged on said input surface

The present disclosure relates to a display adjuster including a rotary adjuster; and an electronic display including a transparent outer layer, wherein the rotary adjuster includes an actuation member and a rotational detection means, wherein the actuation member is rotatably mounted about a rotational axis mounted with bearing means, and the rotary adjuster is arranged on the transparent layer; and the display adjuster also includes a surrounding wall on the transparent layer that surrounds at least the bearing means.

Assembly of an electric display and a control dial having foreign-body ingress protection, view protection, and/or light isolation

A device and method for an operator controlled element with haptic feedback dependent on the detection direction are provided. The device includes a base; an actuating part movably supported on the base; an electrical actuator which is attached to the base and acts on the actuating part in order to drive in a moving manner the actuating part in an excitation direction by means of an electrical excitation signal for generating a haptic feedback; a means for detecting an actuation of the actuating part in two detection directions which in each case include a different angular amount with the excitation direction; an evaluation unit, which is configured, if an actuation in one of the two detection directions is detected, to drive the actuator with a specific electrical excitation signal, depending on the result relating to in which of the two detection directions the actuation was carried out.

Operator control element with haptic feedback which is dependent on the detection direction

An input device includes a fingerprint sensor, an operating layer having a first operating surface, at least one force sensor, and an evaluation unit. The first operating surface has an acquisition surface which acquires a fingerprint of a finger of an operator via the fingerprint sensor. The at least one force sensor measures an operating force of the finger of the operator acting on the first operating surface. The evaluation unit is electrically conductively connected with the fingerprint sensor and with the at least one force sensor. The evaluation unit assigns at least one first switching function to the operating force applied on first operating surface of the operating layer if the operating force measured on the first operating surface exceeds a first threshold value.
