Abstract

Systems and methods for simplifying text entry are provided. A visual keypad may include a plurality of user-selectable buttons corresponding to at least some of the buttons of the alphabet. The layout of the visual keypad may be determined based on an n-gram table. The layout of the visual keypad may be rearranged based at least in part on the most likely next character in response to receiving a user selection of a button on the visual keypad.

Claims

1. A method for supporting user input in a media guidance application implemented at least partially on user equipment, comprising:

accessing an n-gram table;

determining, based at least in part on the accessed n-gram table, a layout of a visual keypad, the visual keypad comprising a plurality of user-selectable buttons corresponding to at least some of the letters of the alphabet; and

displaying the visual keypad with the determined layout.

2. The method of claim 1, wherein the layout is arranged having the most commonly used letters grouped in close proximity to each other.

3. The method of claim 1, wherein the n-gram table is based on a subset of English language.

4. The method of claim 3, wherein the subset comprises only words included in a program schedule database.

5. The method of claim 1, further comprising:

receiving a user selection of a button in the visual keypad; and

in response to receiving the user selection, determining the most likely next character or characters for the user selection based, at least in part, on the accessed n-gram table.

6. The method of claim 5, further comprising:

rearranging the layout to display the most likely next character or characters adjacent to the selected button.

7. The method of claim 6, wherein the n-gram table is based on a subset of English language, the subset comprising only words included in a program schedule database.

8. The method of claim 6, wherein rearranging the layout comprises visually distinguishing buttons that cannot be the next character.

9. The method of claim 6, wherein rearranging the layout comprises removing the buttons that cannot be the next character from the layout.

10. The method of claim 6, wherein rearranging the layout comprises disabling the buttons that cannot be the next character.

11. A system for supporting user input in a media guidance application implemented at least partially on user equipment, comprising:

a user input interface;

a display device; and

control circuitry configured to;

access an n-gram table;

determine, based at least in part on the accessed n-gram table, a layout of a visual keypad, the visual keypad comprising a plurality of user-selectable buttons corresponding to at least some of the letters of the alphabet; and

display the visual keypad with the determined layout.

12. The system of claim 11, wherein the layout is arranged having the most commonly used letters grouped in close proximity to each other.

13. The system of claim 11, wherein the n-gram table is based on a subset of English language.

14. The system of claim 13, wherein the subset comprises only words included in a program schedule database.

15. The system of claim 11, wherein the control circuitry is further configured to:

receive a user selection of a button in the visual keypad; and

in response to receiving the user selection, determine the most likely next character or characters for the user selection based, at least in part, on the accessed n-gram table.

16. The system of claim 15, wherein the control circuitry is further configured to:

rearrange the layout to display the most likely next character or characters adjacent to the selected button.

17. The system of claim 16, wherein the n-gram table is based on a subset of English language, the subset comprising only words included in a program schedule database.

18. The system of claim 16, wherein rearranging the layout comprises visually distinguishing buttons that cannot be the next character.

19. The system of claim 16, wherein rearranging the layout comprises removing the buttons that cannot be the next character from the layout.

20. The system of claim 16, wherein rearranging the layout comprises disabling the buttons that cannot be the next character.
