Abstract

A computer-implemented system for digital ink revisions is provided. The system comprises an annotation module that recognizes a handwritten annotation in an image of a document. The system further comprises a command module that executes a command associated with the recognized handwritten annotation. Methods for using the system are also provided.

Claims

1. A computer-implemented system for digital ink revisions, comprising:

an annotation module that recognizes a handwritten annotation in an image of a document; and

a command module that executes a command associated with the recognized handwritten annotation.

2. The system of claim 1, the annotation module differentiates between an executable handwritten annotation and a non-executable handwritten annotation.

3. The system of claim 2, the command module selectively enables execution of the executable handwritten annotation.

4. The system of claim 3, further comprising a layout manager that adjusts a layout of the document based at least in part upon the executed command.

5. The system of claim 4, the layout manager selectively adjusts the layout of at least a section of the document.

6. The system of claim 5, the section of the document is at least one of a line, a paragraph, a page, a frame, a user-defined section, and an entire document.

7. The system of claim 6, further comprising an undo module that enables undoing a performed command.

8. The system of claim 7, the undo module enables undoing performed commands in a non-linear fashion.

9. A computer-implemented method for digital ink revisions, comprising:

recognizing a handwritten annotation in an image of a document; and

executing a command associated with the handwritten annotation.

10. The computer-implemented method of claim 9, further comprising determining whether a handwritten annotation is executable.

11. The computer-implemented method of claim 10, further comprising selectively enabling execution of the executable handwritten annotation.

12. The computer-implemented method of claim 11, further comprising adjusting a layout of the document based at least in part upon executing the command associated with the handwritten annotation.

13. The computer-implemented method of claim 12, further comprising undoing the executed command associated with the handwritten annotation.

14. The computer-implemented method of claim 13, undoing the executed command associated with the handwritten annotation includes selecting the executed command from a non-linear group of commands.

15. A computer-implemented system for digital ink revisions, comprising:

means for recognizing a handwritten annotation in an image of a document; and

means for executing a command associated with the handwritten annotation.

16. The computer-implemented system of claim 15, further comprising means for determining whether a handwritten annotation is executable.

17. The computer-implemented system of claim 16, further comprising means for selectively enabling execution of the executable handwritten annotation.

18. The computer-implemented system of claim 17, further comprising means for adjusting a layout of the document based at least in part upon executing the command associated with the handwritten annotation.

19. The computer-implemented system of claim 18, further comprising means for undoing the executed command associated with the handwritten annotation.

20. The computer-implemented system of claim 19, means for undoing the executed command associated with the handwritten annotation includes means for selecting the executed command from a non-linear group of commands.
