ABSTRACT:
The projector of the present invention provides a means for interactively displaying and annotating a document image at two separate locations. The projector consists of an image plate having an array of picture elements for displaying the image; a projection mechanism for projecting the image displayed by the image plate onto a projection screen; and a digitizer having a coordinate input array which corresponds to the array of picture elements of the image plate, wherein the image displayed by the image plate changes in response to coordinate inputs to the digitizer. A method for interactively annotating an image communicated between a remote and local image includes the procedure of simultaneously transmitting to the remote projector, annotations made to an image in the local projector.
