Abstract

A mobile communication terminal capable of scrolling through content data includes at least one acceleration key configured to generate an acceleration signal when the acceleration key is activated. A controller is configured to scroll through the content data at a higher speed than a predefined speed based on the acceleration signal.

Claims

1. A mobile communication terminal capable of scrolling through content data, the mobile communication terminal comprising:

at least one acceleration key configured to generate an acceleration signal when the acceleration key is activated; and

a controller configured to scroll through the content data at a higher speed than a predefined speed in response to the acceleration signal.

2. The mobile communication terminal of claim 1, wherein the controller is configured to scroll through the content data on a page by page basis when the acceleration key is activated.

3. The mobile communication terminal of claim 1, wherein the controller is configured to continuously scroll through the content data at the higher speed when the acceleration key is continuously activated.

4. The mobile communication terminal of claim 1, wherein the acceleration key is configured in a form of at least one of a protruded and recessed member.

5. The mobile communication terminal of claim 1, further comprising a search key configured to generate at least one of a scroll signal and a scroll direction signal,

wherein the controller is configured to scroll through the content data in a direction based on the scroll direction signal.

6. The mobile communication terminal of claim 5, wherein the controller is configured to scroll through the content data when the search key is activated for a predetermined period of time.

7. The mobile communication terminal of claim 5, wherein the search key has a circular shape, and the scroll direction indicated by the scroll direction signal dynamically changes when a contact point at the search key changes from one point to another point at the search key while in continuous contact with the search key.

8. The mobile communication terminal of claim 5, further comprising a search direction key configured to continuously scroll through the content data in the direction indicated by the scroll direction signal.

9. The mobile communication terminal of claim 1, further comprising a display to display content data being scrolled by the controller.

10. The mobile communication terminal of claim 1, further comprising means for generating a scroll signal.

11. The mobile communication terminal of claim 10, further comprising means for sensing an input at the scroll signal generating means.

12. The mobile communication terminal of claim 1, further comprising means for generating a signal that causes the controller to continuously scroll through the content data.

13. A mobile communication terminal capable of scrolling through content data, the mobile communication terminal comprising:

an input unit having at least two sensors, the input unit configured to generate a signal based on the number of sensors activated; and

a controller configured to scroll through a number of pieces of content data, or scroll through the content data at a higher speed than a predefined speed based on the signal.

14. A method for scrolling through content data in a mobile communication terminal, the method comprising:

generating a scroll signal;

determining whether an acceleration signal to scroll through the content data at a higher speed than a predefined speed is received; and

scrolling through the content data at the higher speed if the acceleration signal is received.

15. The method of claim 14, further comprising scrolling through the content data on a page by page basis if the acceleration signal is received.

16. The method of claim 14, further comprising:

determining whether a scroll direction signal is received; and

scrolling through the content data in a direction based on the scroll direction signal if the scroll direction signal is received.

17. The method of claim 16, further comprising:

determining whether the scroll direction signal is continuously received for a predetermined period of time; and

scrolling through the content data in the direction based on the scroll direction signal if the scroll direction signal is continuously received for the predetermined period of time.

18. The method of claim 14, further comprising causing a display to display a process of scrolling through the content data.

19. A processor executable medium containing instructions therein, which when executed by a processor causes the processor to perform the method of claim 14.

20. A method for scrolling through content data in a mobile communication terminal, the method comprising:

determining a number of signals generated, the number of signals representing a number of activated sensors; and

scrolling through a number of pieces of content data, or scrolling through the content data at a higher speed than a predefined speed based on the number of signals generated.
