Associating information on a whiteboard with a user
First Claim
Patent Images
1. A method comprising;
- receiving, by a system, a user identifier corresponding to a user, the user identifier having an associated first timing information;
receiving, by the system, information about a stroke generated on a whiteboard, the stroke having an associated second timing information generated independently of the first timing information;
determining, by the system, whether a correlation exist between the user identifier and the stroke based on comparing the first timing information and the second timing information;
generating, by the system, information associating the user identifier with the stroke based at least in part on the comparison; and
storing, by the system, the association information.

Abstract
Techniques for associating strokes information generated at an interactive whiteboard system with a user identifier. The user identifier may, for example, be an image of a user who generated the strokes information. The associating may be performed based upon time stamps associated with the strokes information and the image. Information may be stored indicative of the association between the strokes information and the user identifier.

1. A method comprising;
-
receiving, by a system, a user identifier corresponding to a user, the user identifier having an associated first timing information; receiving, by the system, information about a stroke generated on a whiteboard, the stroke having an associated second timing information generated independently of the first timing information; determining, by the system, whether a correlation exist between the user identifier and the stroke based on comparing the first timing information and the second timing information; generating, by the system, information associating the user identifier with the stroke based at least in part on the comparison; and storing, by the system, the association information. - View Dependent Claims (2, 3, 4, 5, 6)

7. A method comprising:
-
receiving, by a system, strokes information about a set of strokes, the strokes information including first timing information indicating when the set of strokes were generated; receiving, by the system, a user identifier with associated second timing information generated independently of the first timing information; determining, by the system, that a user associated with the user identifier generated the set of strokes by comparing the first timing information with the second timing information; determining, by the system, identity of the user based at least in part on the user identifier; generating, by the system, digital information using the strokes information; selecting, by the system, a handwriting sample for the user; and using, by the system, the handwriting sample to analyze the digital information. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A system comprising:
-
a surface configured to accept user input; an imaging device coupled to the surface and configured to capture images of users using the surface; and a controller coupled to the surface and the imaging device, wherein the controller is configured to; receive information about a stroke generated on the surface, the stroke having an associated first timing information generated in response to the surface accepting the stoke; receive an image of a user from the imaging device, the image having an associated second timing information generated in response to the imaging device capturing the image of the user; compare the first timing information and the second timing information; generate correlation information between the stroke and the image of the user based at least in part on the comparison; and store the correlation information. - View Dependent Claims (16, 17, 18, 19, 20)
