Systems and methods for providing an auxiliary user input device (101, 501, 601) for use with a mobile electronic device (181, 681). The methods involve: releasably securing (703) a first device (101, 601) comprising a resistive touch screen (103, 603) to a second device (181, 681) comprising a capacitive touch screen (183, 683), in a position wherein a primary plane of the capacitive touch screen is substantially aligned in parallel and subjacent to a primary plane of the resistive touch screen; establishing (705) a communication link (641, 643) between a first communications interface (617, 619) in the first device and a second communications interface (657, 659) in the second device; generating resistive touch screen output data in response to user input received (707) at the resistive touch screen; and communicating (713) the resistive touch screen output data from the first device to the second device via the communication link. |
