Abstract
Abstract The invention concerns using multiple computers to hold a conference. Under the invention, an application program can run on a single computer, yet remote participants can issue commands to the program. Remote participants can watch the program operate, because the invention replicates the display window of the running program onto the displays of the remote computers. Any participant can make annotations on the participant's own computer display. The invention copies the annotations to the displays of the other participants.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
128 words
A computer system, comprising: a) multiple computers connected by a data channel; b) program means for running on each computer, comprising one program means which i) transforms input from a user of a computer into an image, which is added to a pre-existing image generated by an application program to form an annotated image, on a display at said computer, and ii) transmits information on the data channel about the annotated image; comprising second program means which iii) replicates the annotated image on the respective displays of other computers; and comprising third program means which iv) accepts commands from selected other computers, and delivers the commands to said application program, wherein said application program means is capable of running independently of said first, second, and third program means.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
76 words
A computer system, comprising: a) multiple computers, each having a display and an operating system; b) program means, running on each computer, which i) allows the user of every computer to select and run an application program, which generates an image on the display of the user's computer; ii) replicates the image on displays of other computers; iii) allows the user of every computer to annotate the image; and iv) replicates the annotations on all displays.
