Abstract

Systems, methods, and devices for interpreting slide gestures as input in connection with push-button keyboards and touch-sensitive user interfaces that include virtual keyboards are disclosed herein. These systems and methods cause an arrangement of alternative key inputs to be displayed as a function of a dynamic user input having an initial key-input and a continuous slide gesture such that the arrangement of alternative key inputs is displayed in the direction of the slide gesture prior to cessation of the slide gesture. The systems and methods also select alternative key inputs and perform certain functions according to the initial key touched and the slide gesture. The described techniques can be used in conjunction with a variety of devices, including handheld devices that include touch-screen interfaces, and mechanical keyboards such as desktop computers, tablet computers, notebook computers, handheld computers, personal digital assistants, media players, mobile telephones, and combinations thereof.

Claims

1. A computer implemented method of generating text input responsive to a dynamic user-touch and slide gesture on a user interface, comprising:

sensing a user-touch within a keyboard area of the user interface, using a processor operatively coupled to the user interface and configured by code executing therein;

detecting, by the configured processor, a slide gesture on the keyboard area following the sensed user-touch;

generating input path data representative of an initial touchdown point of the user-touch and a path of the slide gesture on the keyboard area;

analyzing the input path data, and while the slide gesture continues to be sensed, causing an arrangement of alternative key inputs to be displayed as a function of a keyboard key located at the initial touchdown point and a direction of the slide gesture, wherein the arrangement of alternative key inputs is displayed in the direction of the slide gesture prior to cessation of the slide gesture being sensed; and

upon completion of the user-touch and slide gesture, generating a text input as a function of the key and the path of the slide gesture, wherein the text input executes functions associated with one or more of the displayed alternative key inputs.

2. The method of claim 1, wherein the user interface is a touch interface and the keyboard area is a virtual keyboard area.

3. The method of claim 1, wherein the step of generating a text input is performed prior to cessation of the slide gesture being detected.

4. The method of claim 2, wherein the prescribed arrangement of alternative key inputs are caused to be displayed in the direction of the slide gesture.

5. The method of claim 2, wherein the prescribed arrangement of alternative key inputs is caused to be displayed a distance from a current point of user contact while performing the slide gesture.

6. The method of claim 1, wherein the alternate key inputs in the prescribed arrangement are selected for display as a function of the direction of the slide gesture.

7. The method of claim 1, wherein the arrangement of alternate key inputs displayed varies as a function of the direction of the slide gesture.

8. The method of claim 2 wherein the touch interface is a touch screen.

9. The method of claim 1, wherein the step of detecting the user-touch and slide gesture, further comprises:

receiving, by the configured processor, user input data from the user interface;

processing the user input data to generate one or more input path events, wherein the one or more input path events are representative of the position of the user-touch acquired over time;

determining a displacement of the one or more input path events; and

detecting the slide gesture if the displacement exceeds a predetermined threshold.

10. The method of claim 1, wherein the step of generating the text input further comprises:

identifying a key which corresponds to the initial touchdown point;

comparing the one or more input path events to a database of prescribed input path events, wherein each prescribed input path event is associated with one of the displayed alternative key inputs and the identified key;

if the one or more input path events matches one or more prescribed input path events, generating a text input according to the one or more alternative key inputs associated with the prescribed input path event.

11. The user input device of claim 9 wherein each of the one or more input path events and prescribed input path events include a magnitude and direction.

12. The user input device of claim 1, wherein the text input executes functions associated with a plurality of the alternative key inputs displayed.

13. The user input device of claim 1 wherein the user interface is a mechanical keyboard, and wherein the keyboard area includes a plurality of manual keys that are actuatable along a vertical axis and a plurality of directions in a horizontal plane.

14. The user input device of claim 12, wherein the step of sensing a user touch comprises sensing actuation a particular manual key along the vertical axis, and wherein the step of sensing the slide gesture further comprises sensing actuation of at least the particular manual key in the horizontal axis.

16. The user input device of claim 13, wherein the user interface is a touch interface and the keyboard area is a virtual keyboard area.

17. The user input device of claim 13, wherein the prescribed arrangement of alternative key inputs are caused to be displayed in the direction of the slide gesture.

18. The user input device of claim 13, wherein the prescribed arrangement of alternative key inputs are caused to be displayed a distance from a current point of user contact while performing the slide gesture.

19. The user input device of claim 13, wherein the alternate key inputs in the prescribed arrangement are selected for display as a function of the direction of the slide gesture.

20. The user input device of claim 13, wherein the arrangement of alternate key inputs displayed varies as a function of the direction of the slide gesture.

21. The user input device of claim 14, wherein the touch interface is a touch screen.

22. The user input device of claim 13, wherein the processor configured by executing the input module detects user-touch and a slide gesture, by:

acquiring user input data from the user interface;

processing the user input data to generate one or more input path events, wherein the one or more input path events are representative of the position of the user-touch acquired over time;

determine a displacement of the one or more input path events; and

detect the slide gesture if the displacement exceeds a predetermined threshold.

23. The user input device of claim 13 wherein the processor configured by executing the keyboard control module generates the one or more key inputs by:

identifying a key which corresponds to the initial touchdown point;

comparing the one or more input path events to a database of prescribed input path events, wherein each prescribed input path event is associated with one of the displayed alternative key inputs and the identified key;

if the one or more input path events matches a particular prescribed input path event generating a text input according to a particular alternative text input associated with the particular prescribed input path event.

24. The user input device of claim 13 wherein the user interface is a mechanical keyboard, and wherein the keyboard area includes a plurality of manual keys that are actuatable along a vertical axis and a plurality of directions in a horizontal plane.
