Abstract

The present disclosure provides a touchscreen keyboard with correction of previously input text. A method for correcting text input on an electronic device is described. The method comprises: displaying a virtual keyboard on a touchscreen, the virtual keyboard including a plurality of keys; receiving input from the virtual keyboard; displaying received input in an input field displayed on the touchscreen; and deleting a previous set of characters in the input field when a delete touch gesture is detected in association with a designated key in the virtual keyboard.

Claims

1. A method for correcting text input on an electronic device, comprising:

displaying a virtual keyboard on a touchscreen, the virtual keyboard including a plurality of keys;

receiving input from the virtual keyboard;

displaying received input in an input field displayed on the touchscreen; and

deleting a previous set of characters in the input field when a delete touch gesture is detected in association with a designated key in the virtual keyboard.

2. The method of claim 1, wherein the designated key is a “

Backspace”

key and the delete touch gesture is a back swipe which moves left from the “

Backspace”

key.

3. The method of claim 2, wherein the back swipe has an initial contact point located in or near the “

Backspace”

key and a terminal contact point outside of the virtual keyboard.

4. The method of claim 3, wherein the back swipe is a meta-navigation gesture.

5. The method of claim 1, wherein the designated key is a “

Backspace”

key and the delete touch gesture is a forward swipe which moves right from the “

Backspace”

key.

6. The method of claim 5, wherein the forward swipe has an initial contact point located in or near the “

Backspace”

key and a terminal contact point outside of the virtual keyboard.

7. The method of claim 6, wherein the forward swipe is a meta-navigation gesture.

8. The method of claim 1, wherein the previous set of characters is a set of characters input via character keys of the virtual keyboard.

9. The method of claim 1, wherein the previous set of characters is a predicted set of characters selected in response to received input.

10. The method of claim 1, wherein characters in the previous set of characters which is deleted are sequentially removed from the input field.

11. The method of claim 1, further comprising displaying an animation in association with the designated key in the virtual keyboard when the delete touch gesture is detected.

12. The method of claim 11, wherein the animation comprises a visual representation of a “

Backspace”

key displayed within the virtual keyboard proximate to the “

Backspace”

key which moves across the virtual keyboard in a direction of the delete touch gesture.

13. The method of claim 12, wherein a size of the visual representation of a “

Backspace”

key is proportional to a number of characters in the previous set of characters which is deleted.

14. The method of claim 12, wherein characters in the previous set of characters which is deleted are sequentially removed from the input field, and wherein a size of the visual representation of a “

Backspace”

key increases with each character in the previous set of characters which is removed from the input field.

15. The method of claim 1, further comprising:

inserting a previously deleted set of characters in the input field when an undo delete touch gesture is detected.

16. The method of claim 15, wherein the delete touch gesture has a first direction and the undo delete touch gesture has a second direction opposite to the first direction.

17. The method of claim 16, wherein the delete touch gesture is back swipe and the undo delete touch gesture is a forward swipe.

18. A method for correcting text input on an electronic device, comprising:

displaying a virtual keyboard on a touchscreen, the virtual keyboard including a plurality of keys;

receiving input from the virtual keyboard;

displaying received input in an input field displayed on the touchscreen; and

deleting a previous set of characters in the input field when a delete touch gesture is detected, wherein the delete touch gesture has an initial contact point located outside of the virtual keyboard.

19. The method of claim 18, wherein the initial contact point is located in a non-display area of the touchscreen which surrounds a display area in which the virtual keyboard is displayed.

20. The method of claim 19, wherein the delete touch gesture is a back swipe with the initial contact point in the non-display area right of the virtual keyboard and moves from left across from the virtual keyboard.

21. The method of claim 19, wherein the delete touch gesture is a forward swipe with the initial contact point in the non-display area left of the virtual keyboard and moves from right across from the virtual keyboard.

22. The method of claim 18, wherein the delete touch gesture is a meta-navigation gesture.

23. The method of claim 18, wherein the delete touch gesture is a back swipe having an initial contact point right of the virtual keyboard and moves from left across from the virtual keyboard.

24. The method of claim 18, wherein the delete touch gesture is a forward swipe having an initial contact point left of the virtual keyboard and moves from right across from the virtual keyboard.

25. An electronic device, comprising:

a processor;

a touchscreen coupled to the processor and having a virtual keyboard displayed thereupon;

wherein the processor is configured to;

display a virtual keyboard on a touchscreen, the virtual keyboard including a plurality of keys;

receive input from the virtual keyboard;

display received input in an input field displayed on the touchscreen; and

delete a previous set of characters in the input field when a delete touch gesture is detected in association with a designated key in the virtual keyboard.
