摘要

The device (2) has a display to display variable information e.g. map (11), and a touch screen arranged above the display to input commands by touching the screen. A controller is provided to produce a selection marking (21) that can be displayed on the display, and to move the marking corresponding to a touching movement over the screen. The controller outputs an indication signal for producing a desired display of the variable information. An independent claim is also included for a method of operating an input device.
