Abstract

A method for use in an electronic device including a display and a keyboard, the method including: receiving input reflecting selection of one or more characters through the keyboard; generating a predicted string of one or more characters based on the received input; determining a confidence value for the predicted string, based on a determination that the received input associated with a first one of the one or more selected characters reflects more than a single tap on a key of the keyboard; and displaying the predicted string on the display based on the determined confidence value.

Claims

1. A method for use in an electronic device including a display and a keyboard, the method comprising:

receiving input reflecting selection of one or more characters through the keyboard;

generating a predicted string of one or more characters based on the received input;

determining a confidence value for the predicted string, based on a determination that the received input associated with a first one of the one or more selected characters reflects more than a single tap on a key of the keyboard; and

displaying the predicted string on the display based on the determined confidence value.

2. The method of claim 1, further comprising:

determining that the received input associated with the first one of the one or more selected characters includes at least one of a press on the key of the keyboard longer than a predetermined time period or multiple presses on the key.

3. The method of claim 1, further comprising:

determining that the received input associated with the first one of the one or more selected characters includes a first key selection to switch the keyboard from a first keyboard layout to a second keyboard layout, and a second key selection to input the first one of the one or more selected characters on the second keyboard layout.

4. The method of claim 1, wherein displaying the predicted string on the display comprises:

determining a display ranking for the predicted string based on the determined confidence value; and

displaying the predicted string based on the determined display ranking.

5. The method of claim 4, wherein determining the confidence value comprises:

determining that the predicted string includes the first one of the one or more selected characters; and

determining a relatively high confidence value for the predicted string relative to another predicted string that does not include the first one of the one or more selected characters.

6. The method of claim 5, wherein determining the relatively high confidence value comprises:

assigning an initial confidence value for the predicted string; and

increasing the initial confidence value to the relatively high confidence value.

7. The method of claim 5, wherein determining the relatively high confidence value comprises:

assigning a confidence value for the predicted string, the assigned confidence value being higher than a confidence value determined for any other predicted string that does not include the first one of the one or more selected characters.

8. An electronic device, comprising:

a processor;

a display coupled to the processor; and

a keyboard,

wherein the processor is configured to;

receive input reflecting selection of one or more characters through the keyboard;

generate a predicted string of one or more characters based on the received input;

determine a confidence value for the predicted string, based on a determination that the received input associated with a first one of the one or more selected characters reflects more than a single tap on a key of the keyboard; and

display the predicted string on the display based on the determined confidence value.

9. The electronic device of claim 8, wherein the processor is further configured to determine that the received input associated with the first one of the one or more selected characters includes at least one of a press on the key of the keyboard longer than a predetermined time period or multiple presses on the key.

10. The electronic device of claim 8, wherein the processor is further configured to:

determine that the received input associated with the first one of the one or more selected characters includes a first key selection to switch the keyboard from a first keyboard layout to a second keyboard layout; and

a second key selection to input the first one of the one or more selected characters on the second keyboard layout.

11. A method for use in an electronic device including a display and a keyboard, the method comprising:

detecting that a cursor is positioned in the middle of a string of characters displayed on the display;

receiving through the keyboard an edit input preceding the cursor;

generating a predicted string of characters based on the edit input, the predicted string including a first number of characters corresponding to the characters preceding the cursor in the displayed string, and a second number of characters corresponding to the characters following the cursor in the displayed string;

determining a confidence value for the second number of characters in the predicted string; and

displaying the predicted string on the display based on the determined confidence value.

12. The method of claim 11, wherein receiving the edit input comprises at least one of:

receiving a deleting input deleting one or more of the characters preceding the cursor in the displayed string;

or

receiving an inserting input inserting one or more characters preceding the cursor.

13. The method of claim 11, wherein determining the confidence value comprises:

determining a probability that the characters following the cursor in the displayed string form a word; and

determining the confidence value based on the determined probability.

14. The method of claim 13, further comprising:

determining if the second number of characters in the predicted string match the characters following the cursor in the displayed string.

15. The method of claim 11, further comprising:

determining a first confidence value for the first number of characters in the predicted string;

determining, as a second confidence value, the confidence value for the second number of characters in the predicted string;

determining a display ranking for the predicted string based on the determined first confidence value and the determined second confidence value; and

displaying the predicted string on the display based on the determined display ranking.

16. An electronic device, comprising:

a processor;

a display coupled to the processor; and

a keyboard,

wherein the processor is configured to;

detect that a cursor is positioned in the middle of a string of characters displayed on the display;

receive through the keyboard an edit input preceding the cursor;

generate a predicted string of characters based on the edit input, the predicted string including a first number of characters corresponding to the characters preceding the cursor in the displayed string, and a second number of characters corresponding to the characters following the cursor in the displayed string;

determine a confidence value for the second number of characters in the predicted string; and

display the predicted string on the display based on the determined confidence value.

17. The electronic device of claim 16, wherein the processor is further configured to receive at least one of:

a deleting input deleting one or more of the characters preceding the cursor in the displayed string;

or

an inserting input inserting one or more characters preceding the cursor.

18. The electronic device of claim 16, wherein the processor is further configured to:

determine a probability that the characters following the cursor in the first string form a word.

19. The electronic device of claim 18, wherein the processor is further configured to:

determine a probability that the characters following the cursor in the displayed string form a word; and

determine the confidence value based on the determined probability.

20. The electronic device of claim 16, wherein the processor is further configured to:

determine a first confidence value for the first number of characters in the predicted string;

determine, as a second confidence value, the confidence value for the second number of characters in the predicted string;

determine a display ranking for the predicted string based on the determined first confidence value and the determined second confidence value; and

display the predicted string on the display based on the determined display ranking.
