Abstract

Keyboard gesturing on an input device of a computing system is herein provided. One exemplary computing system includes a host computing device and an input device including one or more keys. The host computing device includes a gesture-recognition engine that is configured to recognize a gesture from touch input reported from a touch-detection engine. The touch-detection engine is configured to detect a touch input directed at a key of the input device. The host computing device further includes an input engine that is configured to interpret a key-activation message based on the gesture recognized by the gesture-recognition engine, where the key-activation message is generated by a key-activation engine of the input device in response to activation of the key.

Claims

1. A computing system, comprising:

a host computing device including a gesture-recognition engine and an input engine; and

an input device including;

one or more keys;

a touch-detection engine to detect a touch input directed at the key and report the touch input to the gesture-recognition engine of the host computing device; and

a key-activation engine to generate a key-activation message responsive to activation of the key;

the gesture-recognition engine of the host computing device configured to recognize a gesture from touch input reported from the touch-detection engine of the input device; and

the input engine of the host computing device configured to interpret the key-activation message based on the gesture recognized by the gesture-recognition engine.

2. The computing system of claim 1, further comprising an adaptive-imaging engine to dynamically change a visual appearance of the key in accordance with rendering information received from the host computing device.

3. The computing system of claim 2, where the adaptive-imaging engine changes the visual appearance of the key responsive to recognition of the gesture by the gesture-recognition engine, the visual appearance of the key changing to correspond to the gesture recognized by the gesture-recognition engine.

4. The computing system of claim 3, where the adaptive-imaging engine is further configured to change the visual appearance of the one or more keys responsive to recognition of the gesture by the gesture-recognition engine, the visual appearance of each of the keys changing to correspond to the gesture recognized by the gesture-recognition engine.

5. The computing system of claim 1, where the keys of the input device include one or more depressible keys and activation of the depressible keys includes mechanical actuation of the depressible keys.

6. The computing system of claim 1, where the gesture-recognition engine is configured to recognize the gesture by determining to which of a plurality of known gestures the touch input reported from the touch-detection engine corresponds.

7. The computing system of claim 1, where the touch-detection engine includes a camera to detect touch input directed at the key.

8. The computing system of claim 1, where the touch-detection engine includes a capacitive sensor to detect touch input directed at the key.

9. The computing system of claim 1, where the key-activation message indicates selection of a capitalization formatting command.

10. The computing system of claim 1, where the key-activation message indicates selection of a bold formatting command.

11. The computing system of claim 1, where the key-activation message indicates selection of an underline formatting command.

12. The computing system of claim 1, where the key-activation message indicates selection of a backspace editing command.

13. A method of dynamically configuring an adaptive input device based on touch gestures, comprising:

displaying a first key image on a key of the adaptive input device;

recognizing a touch gesture performed on the key;

displaying a second key image on the key of the adaptive input device, the second key image corresponding to the touch gesture performed on the key;

detecting a key activation of the key; and

assigning a meaning to the key activation that corresponds to the touch gesture performed on the key.

14. The method of claim 13, where assigning the meaning to the key activation includes assigning a capitalization formatting command to the key activation responsive to a recognized upward gesture performed on the key.

15. The method of claim 13, where assigning the meaning to the key activation includes assigning a bold formatting command to the key activation responsive to a recognized two-finger slide gesture performed on the key.

16. The method of claim 13, where assigning the meaning to the key activation includes assigning an underline formatting command to the key activation responsive to a recognized rightward gesture performed on the key.

17. The method of claim 13, where assigning a meaning to the key activation includes assigning a backspace editing command to the key activation responsive to a recognized leftward gesture performed on the key.

18. The method of claim 13, where the key is a one of a plurality of keys, and where two or more of the plurality of keys change key images responsive to recognition of the touch gesture on one of the plurality of keys.

19. An adaptive input device, comprising:

one or more keys;

an adaptive-imaging engine to dynamically change a visual appearance of a key in accordance with rendering information received from a host computing device;

a touch-detection engine to detect touch input directed at the key;

a gesture-recognition engine to recognize a gesture from touch input detected by the touch-detection engine; and

a key-activation engine to generate a key-activation message responsive to activation of the key, the key-activation message corresponding to the gesture recognized by the gesture-recognition engine.

20. The adaptive input device of claim 19, where the adaptive-imaging engine changes the visual appearance of the key responsive to recognition of the gesture by the gesture-recognition engine, the visual appearance of the key changing to correspond to the gesture recognized by the gesture-recognition engine.
