In a first method step, a position of one or more physical objects on and/or in the vicinity of the touchscreen (2) is identified by the control unit (8), and/or a movement of one or more physical objects on and/or in the vicinity of the touchscreen (2) is identified by the control unit (8). In a further method step, the position and/or the movement of one or more physical objects are/is associated with a gesture within a gesture set by a first association unit (11) within a gesture identification unit (10). The second association unit (12) then passes a key combination to an application (141, 142, 143), and/or a function for the gesture is started within an application (141, 142, 143) by the second association unit (12), and/or the gesture is passed by a second association unit (12) to an application (141, 142, 143).
