Remote highlighting of objects in conferencing system by logically anding a highlight bitmap and a foreground bitmap
First Claim
1. A computer readable medium that stores a computer program for highlighting information on a remote display in a computer conferencing system including a first participant coupled to a second participant via a communication medium, said first participant having a local display and a local input device for controlling a local cursor, said second participant having a remote display, said computer program comprising instructions for:
- selecting a highlighting tool using said local input device, said highlighting tool being a computer implemented function represented by an icon;
displaying said icon representing said highlighting tool on said local display;
activating said highlighting tool using said local input device; and
displaying a highlight image corresponding to said selected highlighting tool on both said local display and said remote display upon the activation of said highlighting tool, said highlight image being displayed on said remote display in a position corresponding to a position of said local cursor on said local display, said step of displaying a highlight image including the steps ofgenerating a highlight bitmap,generating a foreground image bitmap, andlogically ANDing together said highlight bitmap and said foreground image bitmap.

Abstract
An apparatus and method for highlighting information between conference participants in a computer conferencing system is disclosed. In a computer conferencing system including a first participant coupled to a second participant via a communication medium, the first participant having a first display, a first cursor control device, and a first signal generation device, the second participant having a second display, a second cursor control device, and a second signal generation device, a process and apparatus is disclosed for highlighting information on a remote display. This process comprises the steps of: 1) selecting a highlighting tool using the first cursor control device and the first signal generation device, the highlighting tool being a computer implemented function represented by an icon; 2) displaying the icon representing the highlighting tool only on the first display and only while the tool is selected; 3) activating the highlighting tool using the first cursor control device and the first signal generation device; and 4) displaying a highlight image on both the first display, the colored highlight image being displayed by generating a highlight bitmap and a foreground image bitmap and logically ANDing together the highlight bitmap and the foreground image bitmap and the second display, the highlight image being displayed on the second display in a position corresponding to a position of the cursor on the first display.
