ABSTRACT:
A collaborative input system10includes a host computer12. A display14is associated with the host computer. The host computer includes a processor15configured for executing an application to provide an image17on the display14. At least one electromagnetic digitizer18is provided separate from the host computer. The digitizer18has an input surface22defining a display space that is mapped to coincide with the display14, and a pen structure24operatively associated with the input surface such that proximity of the pen structure with respect to the input surface, as a result of a user's input, is detected by the digitizer. A wireless communication link is provided between the host computer and the digitizer such that a user's input can be transmitted from the digitizer, be received by the host computer, and be represented graphically on the display together with the image in real time, thereby permitting the user, associated with the digitizer, to personally provide input to the host computer displaying the image.
