First Claim
Patent Images
1. A method for operating a digital whiteboard having an area, comprising the steps of:
- in response to first opening user input, opening a first drawing region on the whiteboard, the first drawing region having an area smaller than the full digital whiteboard area and further having a first boundary;
establishing a first set of line appearance properties in effect for the first drawing region;
in response to second opening user input, opening a second drawing region on the whiteboard distinct from the first drawing region;
establishing a second set of line appearance properties in effect for the second drawing region, the second set of line appearance properties being non-identical to the set of line appearance properties then in effect for the first drawing region;
in response to first drawing user input indicating drawing of a first line within the first drawing region, displaying the first line on the whiteboard with an appearance that depends on the set of line appearance properties then in effect for the first drawing region;
moving the first boundary in response to the first drawing user input; and
in response to second drawing user input indicating drawing of a second line within the second drawing region, displaying the second line on the whiteboard with an appearance that depends on the set of line appearance properties then in effect for the second drawing region.

Abstract
Roughly described, different drawing regions are opened for different users on the same whiteboard. Each drawing region has its own set of line appearance properties, which the user can set with a toolbar. Lines drawn in a drawing region adopt the line appearance properties then in effect for that drawing region, which also apply to replications of the line on other devices in the collaboration session. As the user draws toward a boundary of the user'"'"'s drawing region, the boundary automatically moves so that the drawing continues to contain the user'"'"'s drawing activity.

15. A digital whiteboard system comprising:
-
a digital whiteboard having an area; a memory; and a data processor coupled to the memory, the data processor configured to; in response to first opening user input, open a first drawing region on the whiteboard, the first drawing region having an area smaller than the full digital whiteboard area and further having a first boundary; establish a first set of line appearance properties in effect for the first drawing region; in response to second opening user input, open a second drawing region on the whiteboard distinct from the first drawing region; establish a second set of line appearance properties in effect for the second drawing region, the second set of line appearance properties being non-identical to the set of line appearance properties then in effect for the first drawing region; in response to first drawing user input indicating drawing of a first line within the first drawing region, display the first line on the whiteboard with an appearance that depends on the set of line appearance properties then in effect for the first drawing region; move the first boundary in response to the first drawing user input; and in response to second drawing user input indicating drawing of a second line within the second drawing region, display the second line on the whiteboard with an appearance that depends on the set of line appearance properties then in effect for the second drawing region.

16. A digital whiteboard system comprising:
-
a wall surface having first and second distinct drawing regions; and a computer system having a database accessible thereto, wherein the database has first storage for storing an identification of first line appearance properties associated with the first drawing region, and second storage for storing an identification of second line appearance properties associated with the second drawing region. - View Dependent Claims (17)
