Abstract

For removing connective strokes, code identifies two connective points in a contiguous written input from a written input device. Each connective point is identified in response to a connective score for the connective point exceeding a connective threshold. The code further removes a connective stroke between the two connective points from the contiguous written input.

Claims

1. An apparatus comprising:

a written input device;

a processor;

a memory that stores code executable by the processor, the code comprising;

code that identifies two connective points in a contiguous written input from the written input device, wherein each connective point is identified in response to a connective score for the connective point exceeding a connective threshold; and

code that removes a connective stroke between the two connective points from the contiguous written input.

2. The apparatus of claim 1, wherein the connective score is calculated as a function of one or more of axes velocities at the connective point and a stroke differential at the connective point.

3. The apparatus of claim 2, wherein the stroke differential is calculated as a difference in stroke pressure between the connective point and adjacent points on the contiguous written input.

4. The apparatus of claim 2, wherein the stroke differential is calculated as a difference in stroke width between the connective point and adjacent points on the contiguous written input.

5. The apparatus of claim 2, wherein the connective score is increased in response to a first axis velocity of less than a velocity threshold and a second axis velocity of less than the velocity threshold.

6. The apparatus of claim 2, wherein the connective score is increased in response to a first axis velocity of zero and a second axis velocity of less than a velocity threshold.

7. The apparatus of claim 2, wherein the connective score is increased for a maximal stroke differential.

8. The apparatus of claim 1, wherein removing the connective stroke forms one or more of a first logogram element from the contiguous written input proceeding a first connective point of the two connective points and a second logogram element from the contiguous written input following a second connective point of the two connective points.

9. A method comprising:

identifying, by use of a processor, two connective points in a contiguous written input from a written input device, wherein each connective point is identified in response to a connective score for the connective point exceeding a connective threshold; and

removing a connective stroke between the two connective points from the contiguous written input.

10. The method of claim 9, wherein the connective score is calculated as a function of one or more of axes velocities at the connective point and a stroke differential at the connective point.

11. The method of claim 10, wherein the stroke differential is calculated as a difference in stroke pressure between the connective point and adjacent points on the contiguous written input.

12. The method of claim 10, wherein the stroke differential is calculated as a difference in stroke width between the connective point and adjacent points on the contiguous written input.

13. The method of claim 10, wherein the connective score is increased in response to a first axis velocity of less than a velocity threshold and a second axis velocity of less than the velocity threshold.

14. The method of claim 10, wherein the connective score is increased in response to a first axis velocity of zero and a second axis velocity of less than a velocity threshold.

15. The method of claim 10, wherein the connective score is increased for a maximal stroke differential.

16. The method of claim 9, wherein removing the connective stroke forms one or more of a first logogram element from the contiguous written input proceeding a first connective point of the two connective points and a second logogram element from the contiguous written input following a second connective point of the two connective points.

17. A program product comprising a computer readable storage medium that stores code executable by a processor, the executable code comprising code to perform:

identifying two connective points in a contiguous written input from a written input device, wherein each connective point is identified in response to a connective score for the connective point exceeding a connective threshold; and

removing a connective stroke between the two connective points from the contiguous written input.

18. The program product of claim 17, wherein the connective score is calculated as a function of one or more of axes velocities at the connective point and a stroke differential at the connective point.

19. The program product of claim 18, wherein the stroke differential is calculated as a difference in stroke pressure between the connective point and adjacent points on the contiguous written input.

20. The program product of claim 18, wherein the stroke differential is calculated as a difference in stroke width between the connective point and adjacent points on the contiguous written input.
