Abstract:
1. A method comprising: releasably securing a first device comprising a resistive touch screen to a second device comprising a capacitive touch screen, in a position wherein a primary plane of said capacitive touch screen is substantially aligned in parallel and subjacent to a primary plane of said resistive touch screen; establishing a communication link between a first communications interface in said first device and a second communications interface in said second device; generating, in said first device, resistive touch screen output data in response to user input received at said resistive touch screen; communicating said resistive touch screen output data from said first device to said second device via said communication link; selectively choosing for control of said second device one or more of a plurality of inputs from the group consisting of said resistive touch screen output data and capacitive touch screen output data generated by said capacitive touch screen; wherein said choosing step is based on an output signal from at least one sensor selected from the group consisting of a humidity sensor and a battery life sensor.
