Abstract

A system and method for editing ink objects recognized in ink input is provided. An ink parser may recognize an ink object in ink input and then an ink editing user interface may edit the ink object recognized by the ink parser. The ink parser may include a chart detector, shape recognizer, and various ink object recognizers such as a chart recognizer, a list detector and a table detector. The various ink object recognizers may recognize particular ink objects. The ink editing user interface may edit the ink object recognized by the ink parser. The ink editing user interface may include a chart editor, list editor, table editor, mode switcher, and a visualizer. The mode switcher may switch the ink editing system between inking mode and ink editing mode.

Claims

1. A computer system for editing ink input, comprising:

an ink parser for recognizing a hand-drawn table in ink input;

a table editor operably coupled to the ink parser for editing the hand-drawn table recognized by the ink parser; and

a mode recognizer operably coupled to the table editor for switching between inking mode for receiving ink input and ink editing mode for editing the hand-drawn table recognized in the ink input.

2. The system of claim 1 wherein the ink parser comprises an operably coupled table detector for detecting the table within ink input.

3. The system of claim 1 wherein the ink parser comprises an operably coupled shape recognizer having a container recognizer and a connector recognizer.

4. A computer-readable medium having computer-executable components comprising the system of claim 1.

5. A method in a computer system for editing ink input, comprising:

receiving ink input;

parsing the ink input;

performing table recognition for an ink object in the ink input;

switching to an editing mode to edit the table;

editing the table by performing an ink editing operation; and

regenerating the ink representing the edited table.

6. The method of claim 5 further comprising performing table detection to detect the table in the ink input.

7. The method of claim 5 further comprising generating a drawing of the table recognized in the ink input.

8. The method of claim 5 wherein editing the table by performing an ink editing operation comprises receiving an indication that a cell in the table is selected for resizing.

9. The method of claim 5 wherein editing the table by performing an ink editing operation comprises receiving an indication that a row in the table is selected for resizing.

10. The method of claim 5 wherein editing the table by performing an ink editing operation comprises receiving an indication that a column in the table is selected for resizing.

11. The method of claim 5 wherein editing the table by performing an ink editing operation comprises receiving an indication of a new size of a cell in the table selected for resizing.

12. The method of claim 5 wherein editing the table by performing an ink editing operation comprises receiving an indication of a new size of a row in the table selected for resizing.

13. The method of claim 5 wherein editing the table by performing an ink editing operation comprises receiving an indication of a new size of a column in the table selected for resizing.

14. The method of claim 5 wherein editing the table by performing an ink editing operation comprises resizing a cell in the table.

15. The method of claim 5 wherein editing the table by performing an ink editing operation comprises resizing a row in the table.

16. The method of claim 5 wherein editing the table by performing an ink editing operation comprises resizing a column in the table.

17. The method of claim 5 wherein editing the table by performing an ink editing operation comprises displaying the contents of a recognized table in a chart.

18. The method of claim 5 further comprising switching to inking mode to receive additional ink input.

19. A computer-readable medium having computer-executable instructions for performing the method of claim 5.

20. A computer system for editing ink input, comprising:

means for receiving ink input;

means for parsing the ink input;

means for performing table recognition for an ink object in the ink input;

means for switching to an editing mode to edit the table;

means for editing the table by performing an ink editing operation; and

means for regenerating the ink representing the edited table.
