Abstract

A system and method for formatting data input on an interactive device. The method includes detecting a stroke input, converting the stroke input into stroke data, making a first determination that the stroke data should be grouped with an existing object group using a proximity threshold, based on the first determination, associating the stroke data with the existing object group, and resetting a timer associated with the existing object group.

Claims

1. A method for formatting data comprising:

detecting a stroke input;

converting the stroke input into stroke data;

making a first determination that the stroke data should be grouped with an existing object group using a proximity threshold;

based on the first determination, associating the stroke data with the existing object group;

after the existing object group is closed;

receiving a modification request to modify the existing object group;

reopening the existing object group in response to the modification request; and

adding additional stroke data associated with a second object group to the existing object group,

after adding the additional stroke data to the existing object group;

receiving a formatting request for the existing object group; and

formatting all stroke data associated with the existing object group in response to the formatting request.

2. The method of claim 1, further comprising:

after associating the stroke data with the existing object group;

resetting a timer associated with the existing object group.

3. The method of claim 1, wherein making the first determination further comprises using a time threshold.

4. The method of claim 1, wherein making the first determination comprises determining that a distance between at least a portion of the stroke input and at least a portion of the existing object group is within the proximity threshold.

5. The method of claim 1, wherein making the first determination further comprises determining that a time elapsed, between the stroke input and at least one other stroke input associated with the existing object group, is within a time threshold.

6. The method of claim 1, further comprising:

detecting a second stroke input;

converting the second stroke input into second stroke data;

making a second determination that the second stroke data should not be grouped with the existing object group using the proximity threshold; and

based on the second determination, associating the second stroke data with a new object group.

7. The method of claim 6, wherein making the second determination comprises determining that a distance between at least a portion of the second stroke input and at least a portion of the existing object group is not within the proximity threshold.

8. The method of claim 6, wherein making the first determination further comprises using a time threshold and wherein making the second determination comprises determining that a time elapsed between the second stroke input and at least one other stroke input associated with the existing object group is not within the time threshold.

9. The method of claim 6, further comprising:

based on the second determination, closing the existing object group.

10. The method of claim 1, wherein the stroke input comprises a marking made by touch input or input via a digital marker.

11. The method claim 1, wherein the existing object group is associated with an object type.

12. The method of claim 11, wherein the object type comprises at least one selected from the group consisting of a marking, a letter, a word, a sentence, and a paragraph.

13. The method of claim 1, further comprising:

prior to detecting the stroke input, obtaining a language selection, wherein the proximity threshold is based, at least in part, on the language selection.

14. The method of claim 1, further comprising:

making a second determination that the stroke data should be grouped with a second existing object group using at least the proximity threshold; and

based on the second determination, associating the stroke data with the second existing object group,

wherein the existing object group is associated with a first object type and the second existing object group is associated with a second object type,

wherein the first object type is different than the second object type.

15. A non-transitory computer readable medium comprising instructions, which when executed by a processor, performs a method, the method comprising:

detecting a stroke input;

converting the stroke input into stroke data;

making a first determination that the stroke data should be grouped with an existing object group using a proximity threshold;

based on the first determination, associating the stroke data with the existing object group;

after the existing object group is closed;

receiving a modification request to modify the existing object group;

reopening the existing object group in response to the modification request; and

adding additional stroke data associated with a second object group to the existing object group,

after adding the additional stroke data to the existing object group;

receiving a formatting request for the existing object group; and

formatting all stroke data associated with the existing object group in response to the formatting request.

16. The non-transitory computer readable medium of claim 15, the method further comprising:

after associating the stroke data with the existing object group;

resetting a timer associated with the existing object group.

17. The non-transitory computer readable medium of claim 15, wherein making the first determination further comprises using a time threshold.

18. The non-transitory computer readable medium of claim 15, wherein making the first determination comprises determining that a distance between at least a portion of the stroke input and at least portion of the existing object group is within the proximity threshold.

19. The non-transitory computer readable medium of claim 15, wherein making the first determination further comprises determining that a time elapsed between the stroke input and at least one other stroke input associated with the existing object group is within a time threshold.

20. The non-transitory computer readable medium of claim 15, the method further comprising:

detecting a second stroke input;

converting the second stroke input into second stroke data;

making a second determination that the second stroke data should not be grouped with the existing object group using the proximity threshold; and

based on the second determination, associating the second stroke data with a new object group.

21. The non-transitory computer readable medium of claim 20, wherein making the second determination comprises determining that a distance between at least a portion of the second stroke input and at least portion of the existing object group is not within the proximity threshold.

22. The non-transitory computer readable medium of claim 20, wherein making the first determination further comprises using a time threshold and wherein making the second determination comprises determining that a time elapsed between the second stroke input and at least one other stroke input associated with the existing object group is not within the time threshold.

23. The non-transitory computer readable medium of claim 20, the method further comprising:

based on the second determination, closing the existing object group.

24. The non-transitory computer readable medium of claim 15, wherein the stroke input comprises a marking made by touch input or input via a digital marker.

25. The non-transitory computer readable medium of claim 15, wherein the existing object group is associated with an object type, wherein the object type comprises at least one selected from the group consisting of a marking, a letter, a word, a sentence, and a paragraph.

26. The non-transitory computer readable medium of claim 15, the method further comprising:

prior to detecting the stroke input, obtaining a language selection, wherein the proximity threshold is based, at least in part, on the language selection.

27. The non-transitory computer readable medium of claim 15, the method further comprising:

making a second determination that the stroke data should be grouped with a second existing object group using at least the proximity threshold; and

based on the second determination, associating the stroke data with the second existing object group,

wherein the existing object group is associated with a first object type and the second existing object group is associated with a second object type,

wherein the first object type is different than the second object type.
