Abstract: A method for generating a haptic feedback on a display area operable by finger movements involves sensing a position of a finger on the display area and modulating a coefficient of friction between the finger and the display area is modulated depending on the position. The touchdown positions of two fingers are determined and the friction between each of the fingers and the display area is changed depending on a distance from the touchdown positions of the fingers simultaneously touching the surface.

Abstract: A method for detecting an operating input performed by a finger involves detecting various contact points of a contour of the finger using a sensor system on a sensor surface. The sensor system includes at least one transmitting unit for transmitting a signal to the finger and at least one receiving unit for receiving a signal reflected by the finger. A surface vibration is introduced into the sensor surface by at least one actuator, the surface vibration changes the frictional resistance between the finger and the sensor surface as a function of the changing contact points of the contour of the finger.

Abstract: An operator control apparatus, in particular for a motor vehicle, having an operating surface for manual action by an element, particularly the finger of a human hand. A sensor interacts with the operating surface such that the sensor generates a signal when the element approaches the operating surface and/or when the operating surface is touched by the element and/or when pressure is applied to the operating surface by the element. The signal is used for switching and/or triggering a function in the style of a switching signal. The actuator is operatively connected to the operating surface, such that a haptic event is producible for the operating surface by means of actuation of the actuator. The actuator is driven electrically and operable by a PWM (pulse width modulation) actuation signal, such that the operating surface is movable in a preselectable manner within a preselectable displacement and/or time.

Abstract: An actuator is connected to an operating element of a manual user interface and outputs a haptic feedback signal to the user via the operating element. The operating element includes a sensor that detects a sensor signal generated by a manual input of the user as a reaction to the emitted feedback signal. The user's reaction time is determined. If the reaction time is shorter than a predetermined limit value, future haptic feedback signals are adjusted in such a way that their haptically perceptible intensity is reduced, and if the reaction time is greater than the predetermined limit value, future haptic feedback signals are changed in such a way that their haptically perceptible intensity is increased.

Abstract: A steering wheel for a motor vehicle is disclosed. The steering wheel includes an optical finger navigation module, at least one further operating element, a steering wheel electronic system and a databus for data transmission between the optical finger navigation module and the steering wheel electronic system. The at least one further operating element is directly connected to the optical finger navigation module via a signal line. The optical finger navigation module is designed in such a way as to receive a signal from the at least one further operating element and relay it on to the steering wheel electronic system via the databus. In this way, no dedicated lines from the operating element to the steering wheel electronic system are necessary. Thus, the construction space for the installation of a device consisting of an optical finger navigation module and a further operating element in a steering wheel is reduced.

Abstract: A method to control functions displayed on a display unit of a vehicle uses gestures carried out in three-dimensional space. When a first gesture carried out in three-dimensional space is detected it is determined whether the detected first gesture is allocated to an activation of an operation of a function. If it is determined that the detected first gesture is the gesture allocated to the activation of the operation of the function, then the function is activated. Next a second gesture carried out in three-dimensional space is detected and it is determined whether the detected second gesture is a gesture allocated to the operation of the function. If it is determined that the detected second gesture is the gesture allocated to the operation of the function then the operation of the function is performed.
