Abstract

A method for a gesture-based function control for an electronic device having a touch-based input interface such as a touch screen is provided. While a selected mode is performed, a gesture launcher mode is activated in response to a user'"'"'s request through a special function key or a multi-touch interaction. When receiving a user'"'"'s gestural input in the gesture launcher mode, the electronic device executes a particular function corresponding to the user'"'"'s gestural input.

Claims

1. A method for a gesture-based function control in an electronic device having a touch-based input interface, the method comprising:

performing a selected mode in response to a user'"'"'s request;

activating a gesture launcher mode in response to a user'"'"'s request in the selected mode;

receiving a user'"'"'s gestural input in the gesture launcher mode; and

executing a particular function associated with the user'"'"'s gestural input.

2. The method of claim 1, wherein the activating of the gesture launcher mode includes:

detecting an occurrence of an input event for the activation of the gesture launcher mode; and

activating the gesture launcher mode in response to the detected input event while keeping the selected mode in an enabled state.

3. The method of claim 2, wherein the input event occurs via detection of a gesture mode shift key equipped in the electronic device being actuated.

4. The method of claim 2, wherein the input event occurs through detection of contact in an arbitrary location on the touch-based input interface.

5. The method of claim 2, wherein the receiving of the user'"'"'s gestural input occurs while the input event is maintained after activating the gesture launcher mode.

6. The method of claim 2, wherein the receiving of the user'"'"'s gestural input occurs while the input event is halted after activating the gesture launcher mode.

7. A method for a gesture-based function control in an electronic device having a touch-based input interface, the method comprising:

detecting an input event for activating a gesture launcher mode by the electronic device while performing a selected mode;

activating the gesture launcher mode in response to the input event;

receiving an input of a predefined user gesture while the detected input event is maintained; and

executing a particular function based on function information corresponding to the user gesture.

8. The method of claim 7, wherein the input event occurs by a gesture mode shift key equipped in the electronic device being actuated or by an arbitrary location of the touch-based input interface being touched.

9. The method of claim 8, wherein the input event includes a tap-and-hold event which occurs on the gesture mode shift key, and wherein the particular function is executed in response to the user gesture being input while the tap-and-hold event is maintained on the gesture mode shift key.

10. The method of claim 8, wherein the input event includes a tap-and-hold event which occurs on the arbitrary location of the touch-based input interface, and wherein the particular function is executed in response to the user gesture being input while the tap-and-hold event is maintained on the arbitrary location of the touch-based input interface.

11. The method of claim 7, further comprising:

forming an additional layer for receiving the user gesture on a currently displayed output data when or after the gesture launcher mode is activated.

12. The method of claim 7, wherein the gesture launcher mode is activated while continuing to display output data created in the selected mode.

13. The method of claim 12, wherein the user gesture is inputted while display of the output data is maintained.

14. The method of claim 7, further comprising:

displaying an output data created depending on the execution of the particular function.

15. The method of claim 7, further comprising:

deactivating the gesture launcher mode when the input event is halted.

16. An electronic device comprising:

a touch-based input interface configured for entering into a gesture launcher mode in response to a predefined input event, and for receiving an input of a user gesture in the gesture launcher mode; and

a control unit configured for executing a particular function in response to the user gesture input on the touch-based input interface.

17. The electronic device of claim 16, further comprising:

a gesture mode shift key for activating the gesture launcher mode.

18. The electronic device of claim 17, wherein the input event occurs through actuation of the gesture mode shift key, and wherein the control unit controls execution of the particular function in response to the user gesture while the input event is maintained on the gesture mode shift key.

19. The electronic device of claim 16, wherein the input event occurs through contact with an arbitrary location of the touch-based input interface, and wherein the control unit controls the execution of the particular function in response to the user gesture while the input event is maintained on the arbitrary location of the touch-based input interface.
