Abstract: A sensing device sensing at least one body part of a user when the body part is arranged in a sensing region of the sensing device is included in an operator control system that also includes a control device controlling a signal apparatus of the operator control system. The sensing device checks whether the body part sensed in the sensing region is in an operator control space that forms a sub-region of the sensing region. The control device actuates the signal apparatus that is used outside the operator control space to output an acknowledgment when the sensing device senses that the body part is inside the operator control space.

Abstract: An operating gesture of a user and at least one spatial position in which the operating gesture is performed are sensed without contact by a sensing apparatus of an operating device of a motor vehicle. Then a function of the motor vehicle is controlled according to the operating gesture if it was sensed that the at least one spatial position lies within a predetermined interaction space. To determine the interaction space, a predetermined determination gesture performed by the user is detected, at least one position in which the determination gesture is performed is sensed, and the at least one sensed position of the determination gesture is defined as a coordinate of the interaction space.

Abstract: In a method for operating a motor vehicle, data obtained from outside the motor vehicle, which indicate the existence of a hazardous situation, are transmitted to a receiving device. A warning concerning the hazardous situation is communicated to the user of the motor vehicle. In addition to the external vehicle data, data obtained from inside the vehicle, which indicate the existence of a hazardous situation, are evaluated. The warning is communicated to the user of the vehicle subject to the evaluation of the data obtained from outside the vehicle and the data obtained from inside the vehicle.

Abstract: At least one display device in a motor vehicle displays graphic information from graphic applications that generate, independently of one another, display contents for an information data set. The graphic applications synchronize themselves by exchanging the information data set or by mutual referencing to the information data set, with the result that firstly one of the applications generates and displays its display content for the information data set in a first region, and then another of the applications generates its display content for the information data set and displays its display content in another region in the passenger compartment. A signaling device signals the synchronization by at least one optical and/or acoustic signal, which is different from the display contents, in the passenger compartment.
