Abstract

Disclosed are systems and methods for facilitating composition of handwritten documents. In one embodiment, a system and method pertain to identifying handwritten input entered in a display of a computing device, and controlling the placement of handwritten input on the display so as to enable uninterrupted handwriting on the display.

Claims

1. A method for facilitating composition of handwritten documents, comprising:

determining how to control the placement of handwritten input within a computing device display;

identifying handwritten input entered within an entry field of the display; and

panning a virtual page on which the handwritten input is written relative to the display such that handwritten input is continuously entered within the entry field of the display by a user without the user moving the user'"'"'s hand across the display, wherein the virtual page is larger than the display and provides the user with an appearance of an actual hardcopy document of the handwritten input.

2. The method of claim 1, wherein determining how to control the placement comprises determining how to control the placement of handwritten input at least in part based upon information contained in a previously-stored handwriting profile.

3. The method of claim 1, further comprising interrupting panning of the virtual page when handwriting is paused.

4. The method of claim 3, further comprising resuming panning of the virtual page when handwriting is resumed.

5. The method of claim 3, further comprising backing up the virtual page when handwriting is paused.

6. The method of claim 5, further comprising shifting the virtual page upward within to the display to facilitate handwriting on a next line of the virtual page.

7. The method of claim 3, further comprising creating the handwriting profile by analyzing the user'"'"'s handwriting style.

8. The method of claim 7, wherein analyzing the user'"'"'s writing style comprises analyzing the speed with which the user handwrites.

9. The method of claim 1, wherein panning a virtual page comprises panning the page based at least in part on information contained in a handwriting profile.

10. The method of claim 1, wherein the virtual page is a letter-sized virtual page.

11. The method of claim 10, further comprising displaying the letter-sized page to the user in the display to provide a what-you-see-is-what-you-get (WYSWYG) view of a document the user has created.

12. A system for facilitating composition of handwritten documents, comprising:

means for identifying handwritten input entered by a user on a touch-sensitive display of a computing device;

means for moving the handwritten input across the display so as to create space for the user to continue entering handwritten input on the display;

means for collecting information about a speed in which a user writes to create a handwriting profile for the user that is used to control a speed for moving the handwritten input across the display; and

means for storing the handwriting profile.

13. The system of claim 12, wherein the means for identifying comprise an entry field designated in the display.

14. The system of claim 12, wherein the means for moving comprise means for panning handwritten input, means for interrupting panning of handwritten input, and means for resuming panning of handwritten input.

15. The system of claim 12, further comprising means for shifting a virtual page on which the handwritten input is written in an upward direction within the display to facilitate handwriting on a next line of the virtual page.

16. A handwriting manager stored on a computer-readable medium, comprising:

logic configured to determine how to control the placement of handwritten input within a display of a computing device;

logic configured to identify handwritten input entered by a user in the computing device display; and

logic configured to control the placement of handwritten input such that handwritten input is continuously entered at a designated position on a virtual page that is larger than the display by a user without the user moving the user'"'"'s hand across the display, wherein the virtual page shows the user a visualization of an actual hardcopy document of the handwritten input.

17. The manager of claim 16, wherein the logic configured to control the placement of handwritten input is configured to pan the virtual page upon which the handwritten input is written across the display in a leftward direction.

18. The manager of claim 17, wherein the logic configured to control the placement of handwritten input is further configured to interrupt panning when handwriting is paused and resume panning when handwriting is resumed.

19. The manager of claim 16, wherein the logic configured to control the placement of handwritten input is configured to shift the position of the virtual page upon which the handwritten input is written in an upward direction within the display.

20. The manager of claim 16, wherein the logic configured to control the placement of handwritten input comprises a handwriting algorithm.

21. The manager of claim 16, wherein the handwriting algorithm is based at least in part upon the user'"'"'s particular writing style.

22. A device, comprising:

a touch-sensitive display with which handwriting is directly entered into the computing device;

a processor; and

memory that comprises a handwriting manager, the handwriting manager comprising logic configured to identify handwritten input entered by a user on the computing device display and logic configured to pan a virtual page upon which the handwritten input is applied such that new handwritten input is continuously entered within a designated area of the display by a user and added to the virtual page without the user having to move the user'"'"'s hand across to the display, the virtual page being larger than the display to show a letter-sized page to the user in the display to provide a what-you-see-is-what-you-get (WYSWYG) view of a document the user has created.

23. The device of claim 22 , wherein the handwriting manager further comprises logic configured to interrupt panning when handwriting is paused and resume panning when handwriting is resumed.

24. The device of claim 22, wherein the handwriting manager further comprises logic configured to shift the position of the virtual page upon which the handwritten input is written in an upward direction within to the display.

25. The device of claim 22, wherein the virtual page is a letter-sized virtual page.
