Abstract

One embodiment provides a method, including: presenting, on an input and display device, one or more input fields for an underlying application; detecting, using the input and display device, one or more handwriting input strokes provided to an input field overlay application; determining, using a processor, an input field targeting characteristic based on the one or more handwriting input strokes; selecting one of the one or more input fields as a target input field based on the input field targeting characteristic; and inserting a converted form of the one or more handwriting input strokes into the target input field. Other embodiments are described and claimed.

First claim

What is claimed is:

1. A method, comprising:
presenting, on an input and display device, two or more adjacent input fields for an underlying application;
detecting, using the input and display device, one or more handwriting input strokes provided to an input field overlay application, wherein the input field overlay application encompasses the two or more adjacent input fields and wherein at least a portion of the one or more handwriting input strokes are detected outside a boundary of the two or more adjacent input fields;
determining, using a processor, an input field targeting characteristic based on the one or more handwriting input strokes, wherein the input field targeting characteristic identifies one of the two or more adjacent input fields for insertion of the one or more handwriting input strokes;
selecting the identified one of the two or more adjacent input fields as a target input field based on the input field targeting characteristic; and
inserting a converted form of the one or more handwriting input strokes into the target input field.

2. The method of claim 1 , wherein the input field targeting characteristic is selected from the group consisting of: a location of a majority of the handwriting input strokes, a location of an initial handwriting stroke, a location of a baseline of the handwriting input strokes, and a center of gravity of the handwriting input strokes.

3. The method of claim 1 , wherein the handwriting input strokes are provided to two of the two or more input fields for the underlying application.

4. The method of claim 1 , wherein the input field targeting characteristic comprises a plurality of input field targeting characteristics.

5. The method of claim 4 , wherein at least one input field targeting characteristic of the plurality of input field targeting characteristics is weighted.

6. The method of claim 5 , wherein weighting of the at least one input field targeting characteristic is based on the underlying application.

7. The method of claim 6 , wherein weighting of the at least one input field targeting characteristic is based on locations of the one or more input fields of the underlying application.

8. The method of claim 5 , wherein the weighting of the at least one input field targeting characteristic is based on a history of user inputs.

9. The method of claim 1 , further comprising providing an indication of the target input field.

10. The method of claim 9 , wherein the indication is a visual indication provided on the display and input device prior to inserting input into the target input field.

11. An electronic device, comprising:
an input and display device;
a processor; and
a memory device that stores instructions executable by the processor to:
present, on the input and display device, two or more adjacent input fields for an underlying application;
detect, using the input and display device, one or more handwriting input strokes provided to an input field overlay application, wherein the input field overlay application encompasses the two or more adjacent input fields and wherein at least a portion of the one or more handwriting input strokes are detected outside a boundary of the two or more adjacent input fields;
determine an input field targeting characteristic based on the one or more handwriting input strokes, wherein the input field targeting characteristic identifies one of the two or more adjacent input fields for insertion of the one or more handwriting input strokes;
select the identified one of the two or more adjacent input fields as a target input field based on the input field targeting characteristic; and
insert a converted form of the one or more handwriting input strokes into the target input field.

12. The electronic device of claim 11 , wherein the input field targeting characteristic is selected from the group consisting of: a location of a majority of the handwriting input strokes, a location of an initial handwriting stroke, a location of a baseline of the handwriting input strokes, and a center of gravity of the handwriting input strokes.

13. The electronic device of claim 11 , wherein the handwriting input strokes are provided to two of the two or more input fields for an underlying application.

14. The electronic device of claim 11 , wherein the input field targeting characteristic comprises a plurality of input field targeting characteristics.

15. The electronic device of claim 14 , wherein at least one input field targeting characteristic of the plurality of input field targeting characteristics is weighted.

16. The electronic device of claim 15 , wherein weighting of the at least one input field targeting characteristic is based on the underlying application.

17. The electronic device of claim 16 , wherein weighting of the at least one input field targeting characteristic is based on locations of the one or more input fields of the underlying application.

18. The electronic device of claim 15 , wherein the weighting of the at least one input field targeting characteristic is based on a history of user inputs.

19. The electronic device of claim 11 , wherein the instructions are further executable by the processor to provide an indication of the target input field.

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 presents, on an input and display device, two or more adjacent input fields for an underlying application;
code that detects, using the input and display device, one or more handwriting input strokes provided to an input field overlay application, wherein the input field overlay application encompasses the two or more adjacent input fields and wherein at least a portion of the one or more handwriting input strokes are detected outside a boundary of the two or more adjacent input fields;
code that determines, using a processor, an input field targeting characteristic based on the one or more handwriting input strokes, wherein the input field targeting characteristic identifies one of the two or more adjacent input fields for insertion of the one or more handwriting input strokes;
code that selects the identified one of the two or more adjacent input fields as a target input field based on the input field targeting characteristic; and
code that inserts a converted form of the one or more handwriting input strokes into the target input field.
