Abstract

Systems, methods, and computer-readable media for processing electronic ink: (a) receive electronic ink input; (b) convert the input to machine-generated objects; and (c) render the objects such that their size substantially corresponds to the input'"'"'s original size. The input ink may constitute text, and the machine-generated objects may correspond to words, lines, and/or other groupings of text generated by a handwriting recognizer. To enable quick and easy identification of recognizer errors, in at least some systems and methods, a user may select one or more words, which will cause the system to display the original ink corresponding to the selected word(s). Such systems also may display alternative words generated by the recognizer corresponding to the selected original ink and allow the user to select one of the alternatives to make corrections in the recognized text (akin to using a spell-checking or handwriting recognition program).

Claims

1. A method, comprising:

receiving electronic ink input;

converting the electronic ink input to one or more machine-generated objects; and

rendering the one or more machine-generated objects such that a size of the machine-generated object or objects substantially corresponds to an original size of the electronic ink input.

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

determining the original size of the electronic ink input.

3. A method according to claim 2, wherein the original size of the electronic ink input is determined based on an average size of at least a portion of the electronic ink input.

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

receiving input selecting at least one object from the rendered machine-generated object or objects; and

displaying the electronic ink input corresponding to the selected machine-generated object or objects.

5. A method according to claim 4, wherein the displayed electronic ink input temporarily replaces the rendered machine-generated object or objects.

6. A method according to claim 1, wherein the one or more rendered machine-generated objects are arranged so as to correspond to an original arrangement of the electronic ink input.

7. A method according to claim 1, wherein the electronic ink input includes electronic ink text input, the one or more machine-generated objects includes machine-generated text, and the size of at least some of the machine-generated objects constitutes a font size of the machine-generated text.

8. A method according to claim 7, further comprising:

determining the original size of the electronic ink text input on a word-by-word basis.

9. A method according to claim 8, wherein the machine-generated text is rendered, on a word-by-word basis, at a font size based on the determined original size of the electronic ink text input.

10. A method according to claim 7, further comprising:

determining the original size of the electronic ink text input as an average size of a line of the electronic ink text input, on a line-by-line basis.

11. A method according to claim 10, wherein the machine-generated text is rendered, on a line-by-line basis, at a font size based on the average size of the electronic ink text input line.

12. A method according to claim 7, further comprising:

receiving input selecting one or more words from the rendered machine-generated text; and

displaying the electronic ink text input corresponding to the selected machine-generated text.

13. A method according to claim 12, further comprising:

displaying machine-generated text alternatives corresponding to the selected one or more words.

14. A method according to claim 13, further comprising:

receiving input selecting a displayed machine-generated text alternative; and

replacing the selected rendered machine-generated text with the selected displayed machine-generated text alternative.

15. A system, comprising:

an input adapted to receive electronic ink input; and

a processor programmed and adapted to;

(a) convert the electronic ink input to one or more machine-generated objects, and (b) render the one or more machine-generated objects such that a size of the machine-generated object or objects substantially corresponds to an original size of the electronic ink input.

16. A system according to claim 15, wherein the electronic ink input includes electronic ink text input, the one or more machine-generated objects includes machine-generated text, and the size of at least some of the machine-generated objects constitutes a font size of the machine-generated text.

17. A system according to claim 16, wherein the input is further adapted to receive a selection of one or more words from the rendered machine-generated text, and wherein the processor is further programmed and adapted to display the electronic ink text input corresponding to the selected machine-generated text and to display machine-generated text alternatives corresponding to the selected one or more words.

18. A system according to claim 17, wherein the input is further adapted to receive a selection of a displayed machine-generated text alternative, and the processor is further programmed and adapted to replace the selected rendered machine-generated text with the selected displayed machine-generated text alternative.

19. A computer-readable medium including computer-executable instructions stored thereon for performing a method, comprising:

receiving electronic ink input;

converting the electronic ink input to one or more machine-generated objects; and

rendering the one or more machine-generated objects such that a size of the machine-generated object or objects substantially corresponds to an original size of the electronic ink input.

20. A computer-readable medium according to claim 19, wherein the electronic ink input includes electronic ink text input, the one or more machine-generated objects includes machine-generated text, and the size of at least some of the machine-generated objects constitutes a font size of the machine-generated text.
