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.

Claims

1. A method, comprising:

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.

2. The method of claim 1, further comprising:

selecting, from the at least one candidate machine input word, a machine input word;

wherein the generating comprises, generating a list comprising at least one spell check 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 spell check word generated by the spell check application 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 spell check word.

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

7. The method of claim 2, further comprising ranking the list comprising at least one spell check word generated by the spell check application 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 spell check word.

9. The method of claim 7, wherein the ranking comprises weighting the list comprising at least one spell check 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 spell check 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 at least one candidate machine input word;

generate, using a spell check application, at least one spell check word using the at least one candidate machine input word; and

provide, on the display device, the at least one spell check word generated by the spell check application.

12. The electronic device of claim 11, wherein the instructions are executable by the processor to:

select, from the at least one candidate machine input word, a machine input word;

wherein the generating comprises, generating a list comprising at least one spell check 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 spell check word generated by the spell check application 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 spell check words.

15. The electronic device of claim 13, wherein to filter comprises weighting the list comprising at least one spell check words 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 spell check 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 spell check 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 spell check word.

19. The electronic device of claim 17, wherein to rank comprises weighting the list comprising at least one spell check 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 at least one candidate machine input words;

code that generates, using a spell check application, at least one spell check word using the at least one candidate machine input word; and

code that provides, on a display device, the at least one spell check word generated by the spell check application.
