Methods for the operator control of electronic appliances and appropriately set-up electronic appliances in which an input of at least one letter is captured independently of an input request, and a volume of data is displayed on a screen of the electronic appliance on the basis of the captured letter. The input may be made by handwriting or by voice input, for example.

In an operating device of a motor vehicle and a method for recording user inputs in a motor vehicle, the operating device includes a control unit and at least one operating element coupled to the control unit, via whose operation a user input is able to be recorded, an approach sensor system being coupled to the control unit, using which an approach of an actuating element, e.g., of a body part, for example, of a finger of a user to the at least one operating element is able to be recorded before the operation of the at least one operating element occurs. The control unit is adapted to, in response to a recorded approach of the actuating element to the at least one operating element, output information in connection with an operation of the operating element before an operation of the operating element occurs.

A method for determining the position of an actuation element, e.g. a finger of a user, in a motor vehicle when the element approaches a surface and to a position determination device, has the following steps: generating an HF signal; coupling the HF signal into the user; transmitting the HF signal via the body of the user; receiving the HF signal that has been transmitted via the body and the actuation element, using several sensors and determining the position of the actuation element using sensor signals of the sensors, the sensor signals forming a measurement for the received signal intensity of the HF signal and are used to first calculate the position of the centre of gravity of the approaching object, in particular the approaching body part comprising the actuation element, and the position of the actuation element is calculated, taking into consideration the position of the centre of gravity.
摘要:
A method for controlling a graphical user interface, wherein a menu is defined, in which several objects of the menu are each associated with a function, and a global input gesture is associated with at least a part of the objects, wherein the input gesture can be executed on a touch-sensitive surface of an input device and different display contents can be displayed on a display surface. In the method, a global input gesture executed on the touch-sensitive surface is captured and, independently of the currently rendered display content on the display surface, a function is executed, which is associated with the object that is associated with the captured input gesture. Further disclosed is an operating device for executing the method.

A display device (3) is coupled to a touch-sensitive position detection unit (5) and a control unit (6) is coupled to the display device (3) and the position detection unit (5). The control unit has an evaluation logic (8) that evaluates touched positions (9) detected by the position detection unit (5) and uses the positions to influence the control of the representation of information on the display device (3) and the calling up of functions and/or the control of systems (11) that can be operated via the display and control device (1). The evaluation logic (8) is designed to evaluate the detected touched positions (9) in a time-resolved manner.

A method for the operation of a capacitive, matrix touchscreen for use in a motor vehicle, wherein touching the matrix touchscreen in the region of a matrix element produces a signal level associated with the matrix element, wherein the extent of a signal level which is produced by touching the matrix touchscreen in the region of the matrix element and which is associated with the matrix element is altered, and wherein the thus modified signal levels of two adjacent matrix elements are taken as a basis for determining whether the two matrix elements are being touched as part of collective areal touching of the matrix touchscreen.

The vehicle system, controlled by control inputs, provides functionalities in the motor vehicle (1) and has an interface (9) for acquiring the control inputs and outputting data as well as a control device (5) for controlling the functionalities in accordance with the acquired control inputs. A storage medium (7) on which instructions explaining the functionalities and/or operation are stored is linked to the control device (5). The control device (5) is designed to retrieve instructions from the storage medium (7) and output the same as part of the instructions via the interface (9). The vehicle system (3, 3′) can be operated in an assistance mode in which the user inputs are interpreted and evaluated as control inputs for the functionalities while instructions explaining the respective activated functionality and/or other operational options are additionally output at the same time.
