A collaborative input system (10) includes a host computer (12). A display (14) is associated with the host computer. The host computer includes a processor (15) configured for executing an application to provide an image (17) on the display (14). At least one electromagnetic digitizer (18) is provided separate from the host computer. The digitizer (18) has an input surface (22) defining a display space that is mapped to coincide with the display (14), and a pen structure (24) operatively 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 (18). A wireless communication link is provided between the host computer (12) and t he digitizer (18) such that a user's input can be transmitted from the digitize r (18), be received by the host computer (12), and be represented graphically on the display together with the image in real time, thereby permitting the use r, associated with the digitizer (18), to personally provide input to the host computer displaying the image.
