Abstract: A device includes a graphical user interface configured to receive a user input by user exertion of force onto the graphical user interface. The device further includes a detection logic operatively connected to the graphical user interface and configured to produce a signal including data indicative of a first amount of force exerted at a location on the graphical user interface. The device also includes an indication logic operatively connected to the detection logic and configured to determine based on the signal including data indicative of the first amount of force exerted at the location on the graphical user interface that the first amount of force is insufficient to command the device to perform an action based on the user input. The indication logic is further configured to produce a signal including data indicating that additional force must be exerted to command the device to perform the action.

Abstract: A mobile wireless communication terminal includes a wireless communication module that is configured to communicate with other communication terminals over a wireless interface, and a controller. The controller is configured to establish a connection with at least one participant wireless communication terminal via the wireless communication module, to receive from the at least one participant wireless communication terminal an identification of a compliant song file stored on the at least one participant wireless communication terminal and having a metadata tag associated therewith indicating that the compliant song file is classified in a prescribed song file category, and to execute playback of the compliant song file.
