Abstract

Briefly, a method and apparatus for recognizing movement of one or more touches across a location on a keyboard grid on a touch panel interface is disclosed. The method may receiving user input with a touch panel interface, recognizing movement of one or more touches across a location on a keyboard grid on the touch panel interface, and performing an action associated with the movement of one or more touches across the location on the keyboard grid on the touch panel interface.

Claims

1. A method comprising:

receiving user input with a touch panel interface;

recognizing movement of one or more touches across a location on a keyboard grid on the touch panel interface, the recognizing comprises;

recording a series of touch instances including taps and sweeping movements on a touch panel with a keyboard grid;

classifying recorded shapes into finger, thumb, and heel shapes; and

classifying the recorded shapes according to one or more attributes comprising one or more of the following;

a keyboard key, a path attribute, an intensity attribute, a directional attribute, or a location attribute; and

performing an action associated with the movement of one or more touches across the location on the keyboard grid on the touch panel interface, the action comprises;

generating a final attribute classification based, at least in part, on the classifications of the recorded shapes, the final attribute classification defines one or more font attributes to be assigned to typed text; and

applying the final attribute classification to the typed text.

2. The method of claim 1, wherein the user input requires only a small and/or dynamically-allocated region of the touch panel.

3. The method of claim 1, wherein the touch panel interface is a screen associated with a handheld device, cell phone or consumer electronic device and a multi-shape, multi-touch gesture including finger and non-finger touches is input anywhere on the screen to activate a desired response.

4. The method of claim 1, further comprising:

recognizing the movement of one or more touches across a location on a keyboard grid on the touch panel; and

implementing a command assigned to the movement or report negative results if the movement is recognized.

5. The method of claim 1, further comprising prompting the user to associate the movement of one or more touches across the location on the keyboard grid on the touch panel interface with a computing event after the movement is not recognized.

6. An apparatus, comprising:

a touch subsystem including a touch panel for receiving user input in the form of movement of one or more touches across a location on a keyboard grid on the touch panel interface; and

a processing unit to recognize the movement of one or more touches across a location on a keyboard grid on the touch panel interface in the user input and perform an action associated with the movement of one or more touches across a location on a keyboard grid on the touch panel interface, wherein;

the recognizing of the movement comprises;

recording series of touch instances including taps and sweeping movements on a touch panel with a keyboard grid,

classifying recorded shapes into finger, thumb, and heel shapes, and

classifying the recorded shapes according to one or more attributes comprising one or more of the following;

a keyboard key, a path attribute, an intensity attribute, a directional attribute, or a location attribute, and

the action comprises;

generating a final attribute classification based, at least in part, on the classifications of the recorded shapes, the final attribute classification defines one or more font attributes to be assigned to typed text; and

applying the final attribute classification to the typed text.

7. The apparatus of claim 6, wherein the user input requires only a small and/or dynamically-allocated region of the touch panel.

8. The apparatus of claim 6, wherein the touch panel interface is a screen associated with a handheld device, cell phone or consumer electronic device and a multi-shape, multi-touch gesture including finger and non-finger touches is input anywhere on the screen to activate a desired response.

9. The apparatus of claim 6, further comprising:

recognizing the movement of one or more touches across a location on a keyboard grid on the touch panel; and

implementing a command assigned to the movement or report negative results if the movement is recognized.

10. The apparatus of claim 6, further comprising prompting the user to associate the movement of one or more touches across the location on the keyboard grid on the touch panel interface with a computing event after the movement is not recognized.

11. A non-volatile computer readable medium encoded with computer executable instructions, which when accessed, cause a machine to perform operations comprising:

receiving user input with a touch panel interface;

recognizing movement of one or more touches across a location on a keyboard grid on the touch panel interface the recognizing of the movement comprises;

recording series of touch instances including taps and sweeping movements on a touch panel with a keyboard grid,

classifying recorded shapes into finger, thumb, and heel shapes, and

classifying the recorded shapes according to one or more attributes comprising one or more of the following;

a keyboard key, a path attribute, an intensity attribute, a directional attribute, or a location attribute; and

performing an action associated with the movement of one or more touches across the location on the keyboard grid on the touch panel interface, the action comprises;

generating a final attribute classification based, at least in part, on the classifications of the recorded shapes, the final attribute classification defines one or more font attributes to be assigned to typed text; and

applying the final attribute classification to the typed text.

12. The non-volatile computer readable medium encoded with computer executable instructions of claim 11, wherein the user input requires only a small and/or dynamically-allocated region of the touch panel.

13. The non-volatile computer readable medium encoded with computer executable instructions of claim 11, wherein the touch panel interface is a screen associated with a handheld device, cell phone or consumer electronic device and a multi-shape, multi-touch gesture including finger and non-finger touches is input anywhere on the screen to activate a desired response.

14. The non-volatile computer readable medium encoded with computer executable instructions of claim 11, further comprising:

recognizing the movement of one or more touches across a location on a keyboard grid on the touch panel; and

implementing a command assigned to the movement or report negative results if the movement is recognized.

15. The non-volatile computer readable medium encoded with computer executable instructions of claim 11, wherein the movement of one or more touches across the location on the keyboard grid on the touch panel interface is not recognized, the user is prompted to associate the movement of one or more touches across the location on the keyboard grid on the touch panel interface with a computing event and wherein the movement of one or more touches across the location on the keyboard grid on the touch panel interface may be pre-defined or defined during use by the user.

16. A handheld device, comprising:
