US Patent 6965373 Controlling wireless peripherals for processor-based systems

A wireless peripheral may include at least one keyboard and at least two key orientations. In one embodiment of the present invention, a pair of keyboards may be provided on opposite sides of the wireless peripheral. Each of said keyboards may drive a separate interface. The interfaces may be oriented on the peripheral so that when a particular key orientation is chosen for use by orienting the peripheral appropriately, its associated interface is aligned with a processor-based system which receives commands from the peripheral. Thus, the effect of the wireless peripheral may be changed depending on its orientation.
