Abstract

A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and/or web link as a second medium). In one particular embodiment, the MMR system includes a method, system, and computer program product for shared document annotation. A shared annotation is received or retrieved for a source document displayed in a browser. A modified document comprising a hotspot corresponding to the shared annotation is displayed in the browser, and upon a printing command, coordinates are captured corresponding to a printed representation of the modified document and the hotspot, resulting in a rendered page layout comprising the printed representation including the hotspot.

Claims

1. A method of shared document annotation, comprising:

displaying a source document in a browser;

receiving a shared annotation and a designation of a portion of the source document associated with the shared annotation;

displaying in the browser a modified document comprising a hotspot corresponding to the designated portion of the source document;

in response to a print command, capturing coordinates corresponding to a printed

representation of the modified document and the hotspot; and

rendering a page layout comprising the printed representation including the hot spot.

2. The method of claim 1, wherein the shared annotation and designation are retrieved from a shared annotation server.

3. The method of claim 2, further comprising:

receiving an additional shared annotation and an additional designation of an additional portion of the source document for association with the additional shared annotation; and

wherein the modified document further comprises the additional shared annotation.

4. The method of claim 1, wherein the shared annotation and designation are added by an end user.

5. The method of claim 1, wherein the browser is a Windows application.

6. The method of claim 1, wherein the browser is Internet Explorer and the source document is an HTML file.

7. The method of claim 1, wherein capturing coordinates further comprises parsing the printed representation for a subset of the coordinates corresponding to the designation for the hot spot.

8. The method of claim 1, further comprising associating one or more clips with the hotspot.

9. The method of claim 1, further comprising storing the page layout.

10. A method of adding a shared document annotation to a document, comprising:

displaying a source document in a browser;

receiving a shared annotation and a designation of a portion of the source document for association with the shared annotation;

displaying in the browser a modified document comprising the shared annotation associated with the portion;

in response to a print command, capturing coordinates corresponding to a printed representation of the modified document and the shared annotation; and

rendering a page layout comprising the printed representation, wherein the portion is a hotspot associated with the shared annotation.

11. A method of displaying a shared document annotation, comprising:

displaying a source document in a browser;

retrieving a shared annotation associated with the source document;

displaying in the browser a modified document comprising the shared annotation;

in response to a print command, capturing coordinates corresponding to a printed representation of the modified document and a location of the shared annotation within the printed representation; and

rendering a page layout comprising the printed representation and a hotspot associated with the location of the shared annotation within the printed representation.

12. A computer program product for shared document annotation, the computer program product comprising:

a computer-readable medium; and

computer program code, coded on the medium, for;

displaying a source document in a browser;

receiving a shared annotation and a designation of a portion of the source document associated with the shared annotation;

displaying in the browser a modified document comprising a hotspot corresponding to the designated portion of the source document;

in response to a print command, capturing coordinates corresponding to a printed representation of the modified document and the hotspot;

and

rendering a page layout comprising the printed representation including the hot spot.

13. The computer program product of claim 12, wherein the shared annotation and designation are retrieved from a shared annotation server.

14. The computer program product of claim 12, further comprising computer program code coded on the medium for:

receiving an additional shared annotation and an additional designation of an additional portion of the source document for association with the additional shared annotation; and

wherein the modified document further comprises the additional shared annotation.

15. The computer program product of claim 12, wherein the shared annotation and designation are added by an end user.

16. The computer program product of claim 12, wherein the browser is a Windows application.

17. The computer program product of claim 12, wherein the browser is Internet Explorer and the source document is an HTML file.

18. The computer program product of claim 12, wherein capturing coordinates further comprises parsing the printed representation for a subset of the coordinates corresponding to the designation for the hot spot.

19. The computer program product of claim 12, further comprising associating one or more clips with the hotspot.

20. The computer program product of claim 12, further comprising storing the page layout.

21. A computer program product for adding a shared document annotation to a document, the computer program product comprising:

a computer-readable medium; and

computer program code, coded on the medium, for;

displaying a source document in a browser;

receiving a shared annotation and a designation of a portion of the source document for association with the shared annotation;

displaying in the browser a modified document comprising the shared annotation associated with the portion;

in response to a print command, capturing coordinates corresponding to a printed representation of the modified document and the shared annotation; and

rendering a page layout comprising the printed representation, wherein the portion is a hotspot associated with the shared annotation.

22. A computer program product for displaying a shared document annotation, the computer program product comprising:

a computer-readable medium; and

computer program code, coded on the medium, for;

displaying a source document in a browser;

retrieving a shared annotation associated with the source document;

displaying in the browser a modified document comprising the shared annotation;

in response to a print command, capturing coordinates corresponding to a printed representation of the modified document and a location of the shared annotation within the printed representation; and

rendering a page layout comprising the printed representation and a hotspot associated with the location of the shared annotation within the printed representation.

23. A system for displaying a source document in a browser;

an annotation module for receiving a shared annotation and a designation of a portion of the source document associated with the shared annotation and displaying a modified document comprising a hotspot corresponding to the designated portion of the source document;

a feature extraction module for, in response to a print command, capturing coordinates corresponding to a printed representation of the modified document and the hotspot; and

a render module for rendering a page layout comprising the printed representation including the hot spot.

24. The system of claim 23, wherein the shared annotation and designation are retrieved from a shared annotation server.

25. The system of claim 24, wherein the annotation module is further configured for:

receiving an additional shared annotation and an additional designation of an additional portion of the source document for association with the additional shared annotation; and

wherein the modified document further comprises the additional shared annotation.

26. The system of claim 23, wherein the shared annotation and designation are received from an end user.

27. The system of claim 23, wherein capturing coordinates further comprises parsing the printed representation for a subset of the coordinates corresponding to the designation for the hot spot.

28. The system of claim 23, further comprising a hotspot module for associating one or more clips with the hotspot.

29. The system of claim 23, further comprising a storage module for storing the page layout.
