This structure can consist of or include, for example, ITO areas or fine wires.
[0028] Fig. 5 shows an embodiment of a method for operating the motor vehicle 1 or the operating device 4. Initially, a query 31 is made as to whether a first touch of the multi-touch screen 11 occurs in an area of an operating region represented by the display 12. If such a first touch of the multi-touch screen 11 occurs, query 31 is followed by a query 32 as to whether a second touch of the multi-touch screen 11 occurs. If no second touch of the multi-touch screen 11 occurs, query 32 is followed by a query 33 as to whether a predetermined time interval has elapsed. If the predetermined time interval has not elapsed, query 33 is again followed by query 32. Otherwise, query 33 is followed by a step 39 in which the first touch of the multi-touch screen 11 in the area of the operating region represented by the display 12 is evaluated as a single touch, and a function associated with this single touch is executed.
[0029] If the multi-touch screen 11 is touched for a second time, query 32 is followed by a query 34 as to whether the second touch also occurs in the area of the operating area in which the first touch occurred. If the second touch does not occur in the area of the operating area in whose operating area the first touch occurred, query 34 is followed by a query 35 as to whether the second touch occurs in an area of a second operating area shown by the display 12. If the second touch occurs in the area of a second operating area shown by the display 12, query 35 is followed by a step 36 in which the second touch is regarded as a first touch in the area of the second operating area shown by the display 12. For this first touch, the described method sequence is also carried out, but beginning with query 32.If the second touch does not occur in an area of a second operating area shown by the display 12, query 35 is followed by step 39.
[0030] If the second touch occurs in the area of the first operating area shown by the display 12, query 34 is followed by query 37 as to whether a double touch in the area of the first operating area shown by the display is assigned a different functionality than a corresponding single touch. If no different functionality is assigned to a double touch, query 37 is followed by step 39. If, however, the double touch is assigned a different functionality, query 37 is followed by query 38 as to whether the distance between the first touch of the multi-touch screen 11 and the second touch of the multi-touch screen 11 is not greater than a predetermined limit. In an advantageous embodiment, such a limit is approximately 20 cm. If the distance between the two touches is greater than the predetermined limit, query 38 is followed by step 39.If, however, the distance between the two touches is not greater than the specified limit, the first touch of the multi-touch screen 11 and the second touch of the multi-touch screen 11 are assigned to the same operating hand or the same operating intention, and the first and second touch of the multi-touch screen 11 are evaluated as a double touch of the multi-touch screen 11 in the area of the first operating area represented by the display 12 (step 40). Furthermore, a function associated with this double touch is executed.
[0031] The described method is described below with reference to Fig. 6 and Fig. 7 by way of example. A map display 50 is shown on the display 12, on which widgets 51, 52, 53 and 54 are superimposed. Widgets 51, 52, 53 and 54 are exemplary embodiments of operating areas, in particular exemplary embodiments of operating areas in the sense of the claims. If the Fig. 7 shown touches 61, 62, 63, 64 of the multi-touch screen 11, according to the procedure according to Fig.5 - assuming, for example, that a double touch in the area of widget 51 is assigned a separate functionality and a double touch in the area of widget 53 is not - the following assignments are made: Touches 61 and 62 are assigned to the same touch intention, i.e., they are interpreted as double touches.
