Abstract

One embodiment provides a method, including: receiving, in an overlay handwriting application, one or more handwriting strokes; processing the one or more handwriting strokes to obtain at least one candidate machine input word; generating, using a spell check application, at least one spell check word using the at least one candidate machine input word; and providing, on a display device, the at least one spell check word generated by the spell check application. Other embodiments are described and claimed.

First claim

What is claimed is:

1. A method, comprising:
receiving, in an overlay handwriting application, one or more handwriting strokes;
processing the one or more handwriting strokes to obtain a plurality of handwriting recognition results;
automatically generating at least one candidate word for each of the plurality of handwriting recognition results, one of the at least one candidate words comprising at least one letter that is different from a recognized letter of the corresponding handwriting recognition result;
determining, using a processor and based on the generating, that there is a common candidate word from the candidate words for the plurality of handwriting recognition results; and
providing, on a display device, the common candidate word.

2. The method of claim 1 , further comprising:
selecting, from the plurality of handwriting recognition results, a machine input word;
wherein the generating comprises, generating a list comprising at least one candidate word; and
wherein the providing comprises, providing the generated list.

3. The method of claim 2 , further comprising filtering the list comprising at least one candidate word prior to the providing.

4. The method of claim 3 , wherein the filtering comprises selecting words included in two or more lists comprising at least one candidate word.

5. The method of claim 3 , wherein the filtering comprises weighting the list comprising at least one candidate word according to a spell check confidence score.

6. The method of claim 3 , wherein the filtering comprises weighting the list comprising at least one candidate word according to a candidate machine input score.

7. The method of claim 1 , further comprising ranking the list comprising at least one candidate word prior to the providing.

8. The method of claim 7 , wherein the ranking comprises promoting words included in two or more lists comprising at least one candidate word.

9. The method of claim 7 , wherein the ranking comprises weighting the list comprising at least one candidate word according to a spell check confidence score.

10. The method of claim 7 , wherein the ranking comprises weighting the list comprising at least one candidate word according to a candidate machine input score.

11. An electronic device, comprising:
an input and display device;
a processor; and
a memory device that stores instructions executable by the processor to:
receive, in an overlay handwriting application, one or more handwriting strokes;
process the one or more handwriting strokes to obtain a plurality of handwriting recognition results;
automatically generate at least one candidate word for each of the plurality of handwriting recognition results, one of the at least one candidate words comprising at least one letter that is different from a recognized letter of the corresponding handwriting recognition result;
determine, based on the generate, that there is a common candidate word from the candidate words for the plurality of handwriting recognition results; and
provide, on the display device, the common candidate word.

12. The electronic device of claim 11 , wherein the instructions are executable by the processor to:
select, from the plurality of handwriting recognition results, a machine input word;
wherein the generating comprises, generating a list comprising at least one candidate word; and
wherein the providing comprises, providing the generated list.

13. The electronic device of claim 12 , wherein the instructions are executable by the processor to: filter the list comprising at least one candidate word prior to the providing.

14. The electronic device of claim 13 , wherein to filter comprises selecting words included in two or more lists comprising at least one candidate word.

15. The electronic device of claim 13 , wherein to filter comprises weighting the list comprising at least one candidate word according to a spell check confidence score.

16. The electronic device of claim 13 , wherein to filter comprises weighting the list comprising at least one candidate word according to a candidate machine input score.

17. The electronic device of claim 12 , wherein the instructions are executable by the processor to: rank the list comprising at least one candidate word generated by the spell check application prior to the providing.

18. The electronic device of claim 17 , wherein to rank comprises promoting words included in two or more lists comprising at least one candidate word.

19. The electronic device of claim 17 , wherein to rank comprises weighting the list comprising at least one candidate word according to a spell check confidence score.

20. A product, comprising:
a storage device having code stored therewith, the code being executable by a processor of an electronic device and comprising:
code that receives, in an overlay handwriting application, one or more handwriting strokes;
code that processes the one or more handwriting strokes to obtain a plurality of handwriting recognition results;
code that automatically generates at least one candidate word for each of the plurality of handwriting recognition results, one of the at least one candidate words comprising at least one letter that is different from a recognized letter of the corresponding handwriting recognition result;
code that determines, based on the generating, that there is a common candidate word from the candidate words for the plurality of handwriting recognition results; and
code that provides, on a display device, the common candidate word.
