FIG. 1 also illustrates a user input system 140, in accordance with an embodiment of the invention. The user input system 140 includes a processor 152, memory 154, an input/output device such as a display 156, a communication interface 158, and a transceiver 160, among other components. The user input system 140 may also be provided with a storage device, such as a microdrive or other device, to provide additional storage. Each of the components 152, 154, 158, and 160, are interconnected using various buses, and several of the components may be mounted on a common motherboard or in other manners as appropriate.

The processor 152 is configured to execute instructions within the user input system 140, including instructions stored in the memory 154. The processor may be implemented as a chipset of chips that include separate and multiple analog and digital processors. The processor may be configured to provide, for example, for coordination of the other components of the user input system 140, such as control of user interfaces, applications run by user input system 140, and wireless communication by user input system 140.
