Method and mobile terminal device for mapping a virtual user input interface to a physical user input interface

The present invention provides a method an a device for mapping a virtual user input interface to a physical user input interface. The method is provided for mapping a virtual user input interface to a physical user input interface on a mobile terminal device. The mobile terminal device comprises a first physical user input interface, a display and a processing unit being connected to said display and said physical user interface, wherein an application is configured for use with a second user interface. The method of the invention comprises detecting an event indicative of an application to be executed that is configured for use with said second user interface and displaying a virtual user input interface representing said second user input interface on said display. If a a physical user input is received on said first physical user input interface, it is mapping to said displayed virtual user input interface, and displayed as an indication of a virtual input on said displayed virtual user input interface.
