Abstract

Methods for communicating between an application and an ink divider object (which stores ink strokes to be divided into groups) may include: (a) issuing a divide request to the ink divider object, optionally by the application; (b) in response to the divide request, calling a divide method, which groups the stored ink strokes into one or more groupings of strokes having a first predetermined granularity (e.g., words, lines, paragraphs, sentences, drawings, etc.); and (c) making information regarding the one or more groupings of strokes available to the application. This “information” made available to the application may include, for example, the actual groupings of the strokes, the number of stroke groupings having the first predetermined granularity, machine generated text corresponding to the stroke groupings, or the like. The results of the divide method may be stored in an ink division result object. In some examples, the ink division result object may include the originally divided strokes and allow retrieval of groupings of strokes of various different granularities. This invention also relates to systems for performing the above methods and various data structures used in performing these methods.

3. A method according to claim 1, wherein the information made available to the application program includes machine-generated text that corresponds to at least one of the one or more groupings of strokes.

4. A method according to claim 1, further comprising:

informing the application program when the grouping has been completed.

5. A method according to claim 1, wherein at least a portion of the information regarding the one or more groupings of strokes made available to the application program is stored in an ink division result object.

6. A method according to claim 1, wherein language is at least one factor considered in grouping the stored ink strokes into one or more groupings of strokes having the first predetermined granularity.

7. A method according to claim 1, wherein the first predetermined granularity is selected from the group consisting of:

word, line, paragraph, sentence, and drawing.

8. A method according to claim 1, wherein the grouping additionally groups the stored ink strokes into one or more groupings of strokes having at least a second predetermined granularity.

9. A method according to claim 1, further comprising:

making information regarding one or more groupings of strokes having a second predetermined granularity available to the application program.

10. A method according to claim 1, further comprising:

changing the stored ink strokes to produce a modified ink stroke set;

issuing a second divide request; and

in response to the second divide request, grouping the modified ink stroke set into one or more groupings.

11. A computer-readable medium having computer-executable instructions for performing a method of making information available to an application program, the method comprising:

storing a plurality of ink strokes;

receiving a divide request;

in response to the divide request, grouping the stored ink strokes into one or more groupings of strokes having at least a first predetermined granularity;

making information regarding the one or more groupings of strokes available to the application program, wherein the information regarding the one or more groupings of strokes includes information indicating a number of groupings of strokes having the first predetermined granularity.

12. A computer-readable medium according to claim 11, wherein the information made available to the application program includes at least one of the one or more groupings of strokes.

13. A computer-readable medium according to claim 11, wherein the information made available to the application program includes machine-generated text that corresponds to at least one of the one or more groupings of strokes.

14. A computer-readable medium according to claim 11, wherein the method further includes:

informing the application when the grouping has been completed.

15. A computer-readable medium according to claim 11, wherein at least a portion of the information regarding the one or more groupings of strokes made available to the application program is stored in an ink division result object.

16. A computer-readable medium according to claim 11, wherein language is at least one factor considered in grouping the stored ink strokes into one or more groupings of strokes having the first predetermined granularity.

17. A computer-readable medium according to claim 11, wherein the first predetermined granularity is selected from the group consisting of:

word, line, paragraph, sentence, and drawing.

18. A computer-readable medium according to claim 11, wherein the grouping additionally groups the stored ink strokes into one or more groupings of strokes having at least a second predetermined granularity.

19. A computer-readable medium according to claim 11, wherein the method further includes:

making information regarding one or more groupings of strokes having a second predetermined granularity available to the application program.

20. A computer-readable medium according to claim 11, wherein the method further includes:

receiving a modified ink stroke set;

receiving a second divide request; and

in response to the second divide request, grouping the modified ink stroke set into one or more groupings.

21. A method of communicating between an application and an ink divider object, the ink divider object storing ink strokes to be divided into groups, comprising:

issuing a divide request to the ink divider object;

in response to the divide request, calling a divide method, which groups the stored ink strokes into one or more groupings of strokes having at least a first predetermined granularity; and

making information regarding the one or more groupings of strokes available to the application, wherein the information regarding the one or more groupings of strokes includes information indicating a number of groupings of strokes having the first predetermined granularity.

22. A method according to claim 21, wherein the information made available to the application includes at least one of the one or more groupings of strokes.
