Abstract: An operating system for a motor vehicle has a steering wheel (10) comprising a steering-wheel rim, a first input device (14) assigned to the steering wheel (10), a second input device (16) assigned to the steering wheel (10), and a processing unit (18) which is connected in a signal-transmitting manner to the first input device (14) and to the second input device (16).

Abstract: A mirror replacement system (12) for a motor vehicle (10) is described, having at least one processor unit (28), an optical sensor unit (14) which generates image and/or video data of the environment of the motor vehicle (10), and a screen (38) which is arranged so as to display at least part of the generated image and/or video data. The mirror replacement system (12) comprises a viewing direction sensor (30) which is arranged so as to determine the viewing direction of the vehicle driver (36) on the screen (38) or the position of the head of the vehicle driver (36). The processor unit (28) is arranged so as to adapt the image and/or video data to be displayed on the screen (38) based on the detected viewing direction or position of the head so that the image and/or video data displayed on the screen (38) are adapted to the position of the head or to the viewing direction of the vehicle driver (36). A method of displaying image and/or video data is furthermore described.
