Abstract
An interface device for placement between a PC and a peripheral device, such as a keyboard or mouse, enables a flow of digital data into and out of a communicating personal digital assistant (PDA). The interface device includes a central processing unit having an input/output to the PC typically at the PS/2 ports (keyboard and/or mouse). The interface device has two input/output ports (infrared and RS 232) for communication to a PDA. Finally the device includes a switch, preferably under software control, to direct and control data flow between the PC, the PDA, and peripheral device. Peripheral device (keyboard or mouse) to PDA, PDA to PC, as well as peripheral device to PC communication can occur. For example, the PDA can act as a touch sensitive surface emulating a mouse-pad wirelessly connected to the PC enabling for example mouse control of projected computer program images for overall computer program control.
