Abstract

Example embodiments relate to adjustment of a virtual keyboard based on an offset of user input. In example embodiments, a computing device displays a virtual keyboard including a number of virtual keys selectable based on touch input. The device may then receive touch user inputs, where each user input corresponds to a selection of a particular virtual key. In response, the device may adjust a position and/or size of at least a given virtual key based on an offset with respect to the virtual key of each user input corresponding to the virtual key.

Claims

1. A computing device comprising:

a touch-enabled display; and

a processor to;

display a virtual keyboard on the touch-enabled display, the virtual keyboard including a plurality of virtual keys selectable based on input provided to the touch-enabled display;

receive a plurality of user inputs provided to the touch-enabled display, each user input corresponding to a selection of a particular virtual key of the plurality of virtual keys, and

adjust a position of at least a first virtual key based on an offset with respect to the first virtual key of each user input corresponding to the first virtual key.

2. The computing device of claim 1, wherein the processor is additionally to:

adjust the position of the first virtual key based on the offset of each user input corresponding to the first virtual key from a center coordinate of the first virtual key.

3. The computing device of claim 2, wherein the processor is additionally to:

adjust the position of the first virtual key according to an average vector calculated from vectors formed between the center coordinate and a coordinate of each user input corresponding to the first virtual key.

4. The computing device of claim 1, wherein the processor is additionally to:

increase or decrease a size of the first virtual key based on a spatial distribution of the user inputs corresponding to the first virtual key.

5. The computing device of claim 1, wherein the processor is to adjust the position of at least the first virtual key based upon a predetermined number of most recent user inputs.

6. The computing device of claim 1, wherein the processor is additionally to:

adjust a position of each remaining virtual key, wherein the adjusted position for a particular virtual key is based on an offset of each user input corresponding to the particular virtual key.

7. The computing device of claim 1, wherein, to adjust the position of at least the first virtual key, the processor is to:

shift a position of the virtual keyboard based on an average offset of each of the plurality of user inputs from the corresponding virtual keys.

8. The computing device of claim 7, wherein the processor is additionally to:

shift a position of a first portion of the virtual keyboard based on the average offset for virtual keys included in the first portion, and

shift a position of a second portion of the virtual keyboard based on an average offset for virtual keys included in the second portion.

9. The computing device of claim 1, wherein the processor is additionally to:

rotate an outline of the virtual keyboard to a new orientation to fit the adjusted position of at least the first virtual key.

10. The computing device of claim 9, wherein the processor is additionally to:

rotate each virtual key individually to match the new orientation of the outline of the virtual keyboard.

11. A non-transitory machine-readable storage medium encoded with instructions executable by a processor of a computing device for adjusting a virtual keyboard, the machine-readable storage medium comprising:

instructions for displaying a virtual keyboard including a plurality of virtual keys selectable based on touch input;

instructions for receiving a plurality of user inputs, each user input corresponding to a selection of a particular virtual key of the plurality of virtual keys; and

instructions for adjusting a position of each virtual key, wherein the adjusted position for a particular virtual key is determined based at least on an offset of the user inputs corresponding to the particular virtual key with respect to a predetermined position on the particular virtual key.

12. The non-transitory machine-readable storage medium of claim 11, wherein the instructions for adjusting are configured to adjust the position of each virtual key individually based on the offset of the user inputs corresponding to the virtual key.

13. The non-transitory machine-readable storage medium of claim 11, wherein the instructions for adjusting are configured to adjust the position of the virtual keyboard as a whole based on an average offset of the plurality of user inputs.

14. A method comprising:

displaying, by a computing device, a virtual keyboard including a plurality of virtual keys selectable with touch input;

receiving a plurality of user inputs, each user input corresponding to a selection of a particular virtual key of the plurality of virtual keys;

determining a plurality of offsets, wherein each offset is based on a distance of a particular user input from a predetermined position on the corresponding virtual key; and

adjusting the position of each virtual key on the virtual keyboard based on the determined plurality of offsets.

15. The method of claim 14, wherein the adjusting comprises moving the entire virtual keyboard according to an average offset of the plurality of offsets.
