Abstract

Various embodiments related to the correction of typographical errors on touch displays are disclosed. One disclosed embodiment includes a portable computing device comprising a touch-sensitive display device, a logic subsystem, and memory comprising instructions executable by the logic subsystem to perform a method of correcting typographical errors displayed on the touch-sensitive display device. The instructions are executable to identify a typographical error within text displayed on the display, and upon identifying the typographical error, highlight on the display the typographical error. The instructions are further executable to detect a gesture-based touch input selecting a text replacement for correcting the typographical error, and, upon detecting the gesture-based touch input, if a release of the gesture-based touch input is detected within a predefined region associated with a location of the typographical error, then display on the display a replacement of the typographical error with the text replacement.

Claims

1. A portable computing device comprising:

a touch-sensitive display device;

a logic subsystem; and

memory comprising instructions executable by the logic subsystem to;

identify a typographical error within text displayed on the display device;

upon identifying the typographical error, highlight on the display device the typographical error;

detect a gesture-based touch input selecting a text replacement for correcting the typographical error; and

upon detecting the gesture-based touch input, if a release of the gesture-based touch input is detected within a predefined region associated with a location of the typographical error, then display on the display device a replacement of the typographical error with the text replacement.

2. The portable computing device of claim 1, wherein the instructions are executable to detect the gesture-based touch input selecting the text replacement by receiving a touch input over the text replacement and by detecting a movement of the gesture-based touch input on the display device, and wherein the instructions are further executable to move a location of an image of the text replacement in correspondence with the gesture-based touch input.

3. The portable computing device of claim 2, wherein the instructions are further executable to, upon detecting the gesture-based touch input, if a release of the gesture-based touch input is detected outside of the predefined region associated with the location of the typographical error, then not to display the replacement of the typographical error with the text replacement.

4. The portable computing device of claim 1, wherein the instructions are further executable to highlight the typographical error after identifying the typographical error.

5. The portable computing device of claim 1, wherein the instructions are further executable to detect a gesture-based touch input selecting a cursor from a cursor key of a virtual keyboard displayed on the display device, the cursor configured for gesture-based drag-and-drop placement within text displayed on the display device.

6. The portable computing device of claim 1, wherein identifying the typographical error comprises identifying an error within a word displayed on the display device.

7. The portable computing device of claim 6, wherein the replacement text comprises a letter selected from a virtual keyboard displayed on the display device that is dragged and dropped over the predefined region associated with the location of the typographical error.

8. The portable computing device of claim 1, wherein identifying the typographical error comprises identifying a misspelled word displayed on the display device.

9. The portable computing device of claim 8, wherein the replacement text comprises a candidate word dragged from a candidate window displayed on the display device and dropped over the predefined region associated with the location of the typographical error, the candidate window comprising one or more candidate words suggested for replacement of the misspelled word.

10. The portable computing device of claim 1, wherein the gesture-based touch input selecting the text replacement comprises a touch-and-hold gesture.

11. A method of correcting typographical errors displayed on a touch-sensitive display of a portable computing device, the method comprising:

identifying a typographical error within text displayed on the display, the typographical error comprising an error within a word displayed on the display;

upon identifying the typographical error, highlighting on the display the typographical error;

detecting a gesture-based touch input selecting a replacement letter from a virtual keyboard displayed on the display;

detecting a change in a location of the gesture-based touch input, and in response, moving a location of an image of the replacement letter displayed on the display in correspondence with the gesture-based touch input;

detecting a release of the gesture-based touch input; and

if the release of the gesture-based touch input is detected within a predefined region associated with a location of the typographical error, displaying on the display replacement of the typographical error with the replacement letter.

12. The method of claim 11, wherein the typographical error further comprises a single letter.

13. The method of claim 12, wherein highlighting on the display the typographical error comprises highlighting the single letter.

14. The method of claim 11, wherein highlighting on the display the typographical error comprises highlighting the word.

15. The method of claim 11, wherein detecting the gesture-based touch input selecting the replacement letter from the virtual keyboard comprises receiving a touch input over the replacement letter and detecting a movement of the touch input on the display.

16. The method of claim 11, further comprising, if the release of the gesture-based touch input is detected outside of the predefined region associated with the location of the typographical error, removing the image of the text replacement from the display.

17. The method of claim 11, further comprising, if the release of the gesture-based touch input is detected outside of the predefined region associated with the location of the typographical error, not displaying on the display replacement of the typographical error with the replacement letter.

18. A method of correcting typographical errors displayed on a touch-sensitive display of a mobile computing device, the method comprising:

identifying a typographical error within text displayed on the display, the typographical error comprising a misspelled word displayed on the display;

upon identifying the typographical error, highlighting on the display the typographical error;

displaying on the display a candidate window including one or more candidate words suggested for replacement of the typographical error;

detecting a gesture-based touch input selecting one of the candidate words from the candidate window to be a selected candidate word;

detecting a change in a location of the gesture-based touch input, and in response, moving a location of an image of the selected candidate word displayed on the display in correspondence with the gesture-based touch input;

detecting a release of the gesture-based touch input; and

if the release of the gesture-based touch input is detected within a predefined region associated with a location of the typographical error, displaying on the display a replacing of the typographical error with the selected candidate word.

19. The method of claim 18, wherein detecting the gesture-based touch input selecting one of the candidate words from the candidate window comprises receiving a touch input over the selected candidate word and detecting a movement of the touch input on the display.

20. The method of claim 18, further comprising detecting another typographical error, detecting another gesture-based touch input selecting another one of the candidate words from the candidate window, detecting a release of that gesture-based touch input outside of the predefined region associated with a location of that typographical error, and in response, not displaying a replacing of the typographical error.
