Abstract

A device receives one or more input keys via a keypad associated with the device, where the keypad is separate from a display associated with the device. The device also determines one or more predicted words based on the received one or more input keys, and illuminates one or more keys associated with the keypad that correspond to one or more characters provided in the one or more predicted words.

Claims

1. A method comprising:

receiving, by a computing device and via a keypad associated with the computing device, information identifying one or more inputs,

the keypad corresponding to a mechanical keypad that is separate from a display associated with the computing device,

the keypad including a plurality of physical keys,

each key, of the plurality of physical keys, corresponding to a respective character,

the one or more inputs corresponding to a selection of one or more keys, of the plurality of physical keys, to cause one or more characters to be provided for presentation on the display, and

each key, of the plurality of physical keys, corresponding to a respective set of controllable light segments capable of illuminating the key,

the respective set of controllable light segments, for each key of the plurality of physical keys, being separately controllable from the respective set of controllable light segments for each other key of the plurality of physical keys, and

the keypad and the display being connected via one or more wired or wireless connections;

determining, by the computing device, the one or more characters that correspond to the one or more inputs;

providing, by the computing device, the one or more characters for presentation on the display;

determining, by the computing device, a predicted word based on the one or more characters;

determining, by the computing device, one or more predicted characters included in the predicted word,

the predicted word including the one or more characters and the one or more predicted characters, and

the one or more predicted characters corresponding to a plurality of additional inputs necessary to complete the predicted word;

determining, by the computing device, a particular key, of the plurality of physical keys of the keypad, that corresponds to a predicted character of the one or more predicted characters;

identifying, by the computing device, the respective set of controllable light segments that corresponds to the particular key; and

energizing, by the computing device, the respective set of controllable light segments to illuminate the particular key.

2. The method of claim 1, further comprising:

providing, for presentation on the display, one or more of the one or more predicted characters.

3. The method of claim 1, further comprising:

receiving information identifying at least one more input after a user selects one or more of the particular key or one or more other keys of the plurality of physical keys;

determining whether a word that includes characters corresponding to the one or more inputs and the at least one more input is stored in a storage device associated with the computing device; and

storing the word in the storage device when the word is not stored in the storage device.

4. The method of claim 1, where determining the predicted word comprises:

determining the predicted word by comparing the one or more characters with a dictionary of words stored in a storage device of the computing device.

5. The method of claim 1, where determining the predicted word comprises:

using a Text on 9 keys (T9) predictive text dictionary to determine the predicted word based on the one or more characters.

6. The method of claim 1,

where the one or more characters and the one or more predicted characters include all characters that are in the predicted word.

7. The method of claim 1, where the respective set of controllable light segments is part of a backlight that includes a combination of colored and non-colored light sources.

8. The method of claim 1, where the respective set of controllable light segments is provided under and not engaging the particular key.

9. A system comprising:

a keyboard that includes a plurality of physical keys,

each key, of the plurality of physical keys, corresponding to a respective character,

each key, of the plurality of physical keys, corresponding to a respective set of controllable light segments capable of illuminating the key,

the respective set of controllable light segments, for each key of the plurality of physical keys, being separately controllable from the respective set of controllable light segments for each other key of the plurality of physical keys, and

the keyboard being physically separate from a display associated with the system; and

one or more processors to;

receive information identifying one or more inputs via the keyboard,

determine one or more characters that correspond to the one or more inputs,

provide, for presentation on the display, the one or more characters,

determine a predicted word based on the one or more characters,

determine one or more predicted characters that are included in the predicted word,

the predicted word including the one or more characters and the one or more predicted characters, and

the one or more predicted characters corresponding to a plurality of additional inputs necessary to complete the predicted word,

determine a particular key, of the plurality of physical keys of the keyboard, that corresponds to a predicted character of the one or more predicted characters,

identify the respective set of controllable light segment that corresponds to the particular key, and

energize the respective set of controllable light segments to illuminate the particular key.

10. The system of claim 9, where the one or more processors are further to:

provide, for presentation on the display, one or more of the one or more predicted characters.

11. The system of claim 9, where the one or more processors are further to:

receive information identifying at least one more input after a selection of the particular key or one or more other keys of the plurality of physical keys,

determine if a word that includes characters corresponding to the one or more inputs and the at least one more input is stored in a storage device of the system, and

store the word in the storage device when the word is not stored in the storage device.

12. The system of claim 9, where, when determining the predicted word, the one or more processors are to:

determine the predicted word by comparing the one or more characters corresponding to the one or more inputs with a dictionary of words stored in a storage device of the system.

13. The system of claim 9, where, when determining the predicted word, the one or more processors are to:

use a Text on 9 keys (T9) predictive text dictionary to determine the predicted word based on the one or more characters.

14. The system of claim 9, where the particular key is provided on a touch membrane formed over the respective set of controllable light segments.

15. The system of claim 9,

where the keyboard is provided on a touch membrane, and

where the touch membrane is provided over a backlight that includes the respective set of controllable light segments.

16. A non-transitory computer-readable medium storing instructions, the instructions comprising:

one or more instructions that, when executed by at least one processor, cause the at least one processor to;

the keyboard including a plurality of physical keys,

each key, of the plurality of physical keys, corresponding to a respective character,

the one or more inputs corresponding to a selection of one or more keys, of the plurality of physical keys, to cause one or more characters to be provided for presentation on the display, and
