Abstract

A method for an electronic device having a display, including, displaying, on the display, a first virtual keyboard including a set of keys, wherein each key of the set of keys is associated with one or more characters, receiving an input reflecting selection of one or more keys of the set of keys, determining, based on the selection, one or more subsequent candidate input characters and one or more word predictions corresponding to the one or more subsequent candidate input characters, displaying, on the display, a second virtual keyboard including a second set of keys, wherein the second set of keys comprises one or more keys associated with the one or more word predictions positioned based, at least in part, on the one or more subsequent candidate input characters. An electronic device including a display, a memory, and a processor, the processor being configured to execute the method.

Claims

1. A method for an electronic device having a display, the method comprising:

displaying, on the display, a first virtual keyboard including a set of keys, wherein each key of the set of keys is associated with one or more characters;

receiving an input reflecting selection of one or more keys of the set of keys;

determining, based on the selection, one or more subsequent candidate input characters and one or more word predictions corresponding to the one or more subsequent candidate input characters;

displaying, on the display, a second virtual keyboard including a second set of keys, wherein the second set of keys comprises one or more keys associated with the one or more word predictions positioned based, at least in part, on the one or more subsequent candidate input characters.

2. The method of claim 1, further comprising:

displaying, on the display, the first virtual keyboard when a precondition is met.

3. The method of claim 2, wherein the precondition comprises one of:

receiving an input reflecting selection of a specific key of the second virtual keyboard;

receiving an input reflecting selection of a key associated with a word prediction;

detecting a swipe input across the second virtual keyboard;

detecting a swipe input outside of the second virtual keyboard;

or

determining that a predetermined time period has elapsed without receiving an input.

4. The method of claim 3, wherein the predetermined time period is in the range of 1 to 4 seconds.

5. The method of claim 1, wherein, for each key of the second virtual keyboard that is associated with a word prediction, the width of the key is determined based on the length of the word prediction.

6. The method of claim 1, wherein the keys of the second virtual keyboard do not overlap with one another.

7. The method of claim 1, wherein at least one of the keys of the second virtual keyboard are associated with one or more of the subsequent candidate input characters.

8. The method of claim 1, wherein at least one of the keys of the second virtual keyboard associated with one or more of the word predictions is positioned in the proximity of one or more subsequent candidate input characters corresponding to the one or more word predictions.

9. The method of claim 1, wherein at least one of the keys of the second virtual keyboard is displayed in a form that enhances the visibility of the keys.

10. The method of claim 1, wherein at least one of the one or more word predictions is associated with the highest probability of being the next received input.

11. An electronic device comprising:

a display, configured to display characters;

a memory storing one or more instructions; and

a processor configured to execute the one or more instructions to perform operations comprising;

displaying, on the display, a first virtual keyboard including a set of keys, wherein each key of the set of keys is associated with one or more characters;

receiving an input reflecting selection of one or more keys of the set of keys;

determining, based on the selection, one or more subsequent candidate input characters and one or more word predictions corresponding to the one or more subsequent candidate input characters;

displaying, on the display, a second virtual keyboard including a second set of keys, wherein the second set of keys comprises one or more keys associated with the one or more word predictions positioned based, at least in part, on the one or more subsequent candidate input characters.

12. The electronic device of claim 11, wherein the processor is configured to execute the one or more instructions to further perform:

displaying, on the display, the first virtual keyboard when a precondition is met.

13. The electronic device of claim 12, wherein the precondition comprises one of:

receiving an input reflecting selection of a specific key of the second virtual keyboard;

receiving an input reflecting selection of a key associated with a word prediction;

detecting a swipe input across the second virtual keyboard;

detecting a swipe input outside of the second virtual keyboard;

or

determining that a predetermined time period has elapsed without receiving an input.

14. The electronic device of claim 13, wherein the predetermined time period is in the range of 1 to 4 seconds.

15. The electronic device of claim 11, wherein, for each key of the second virtual keyboard that is associated with a word prediction, the width of the key is determined based on the length of the word prediction.

16. The electronic device of claim 11, wherein the keys of the second virtual keyboard do not overlap with one another.

17. The electronic device of claim 11, wherein at least one of the keys of the second virtual keyboard are associated with one or more of the subsequent candidate input characters.

18. The electronic device of claim 11, wherein at least one of the keys of the second virtual keyboard associated with one or more of the word predictions is positioned in the proximity of one or more subsequent candidate input characters corresponding to the one or more word predictions.

19. The electronic device of claim 11, wherein at least one of the keys of the second virtual keyboard is displayed in a form that enhances the visibility of the keys.

20. The electronic device of claim 11, wherein at least one of the one or more word predictions is associated with the highest probability of being the next received input.
