Abstract

Aspects of the present invention relate to the creation of an ink font. Based on characteristics of handwritten characters, the collection of characters may be scaled so as to adjust the size of the font to match predefined size values or relationships.

Claims

1. A method for adjusting an input region comprising the steps of:

receiving handwritten characters in an input region on a display;

determining an average height of the received characters; and

adjusting the position of one of a baseline, a center line, or a top line of the input region, independantly of each other, based on the average height of the received characters.

2. The method according to claim 1, wherein the received characters include normal characters.

3. The method according to claim 1, wherein the received characters include ascent characters.

4. The method according to claim 1, wherein the received characters include descent characters.

5. The method according to claim 1, wherein the handwritten characters are received from a digitizer.

6. The method of claim 1, wherein the position of the center line of the input region is adjusted based on the average height of the received characters without adjusting the top line or the base line.

7. A system for adjusting an input region comprising:

means for receiving handwritten characters in an input region on a display;

means for determining an average height of the received characters; and

means for adjusting the position of one of a baseline, a center line, or a top line of the input region, independently of each other, based on the average height of the received characters.

8. The system according to claim 7, wherein the received characters include normal characters.

9. The system according to claim 7, wherein the received characters include ascent characters.

10. The system according to claim 7, wherein the received characters include descent characters.

11. The system according to claim 7, wherein the means for receiving handwritten characters includes a digitizer.

12. The system of claim 7, wherein the position of the center line of the input region is adjusted based on the average height of the received characters without adjusting the top line or the base line.

13. One or more tangible computer readable media storing computer executable instructions which, when executed, cause a computer to perform at least the following steps:

receiving handwritten characters in an input region on a display;

determining an average height of the received characters; and

adjusting the position of one of a baseline, a center line, or a top line of the input region, independantly of each other, based on the average height of the received characters.

14. The computer readable media of claim 13, wherein the computer executable instructions further cause the computer to perform the step of:

saving the adjusted position of at least one of the baseline, the center line, and the top line.

15. The computer readable media of claim 14, wherein the computer executable instructions further cause a computer to perform the step of:

initializing the character input region using the saved position of at least one of the baseline, the center line, and the top line.

16. The computer readable media of claim 13, wherein the identity of the received handwritten characters is predetermined.

17. The computer readable media of claim 13, wherein the received handwritten characters are selected from a predetermined set of characters.

18. The computer readable media of claim 13, wherein the received handwritten characters are received from a digitizer.

19. The computer readable media of claim 13, wherein the position of the center line of the input region is adjusted based on the average height of the received characters without adjusting the top line or the base line.
