Abstract

The system and method consistent with the present invention provides improved graphical navigation tool for electronic devices. The graphical navigation tools may be used to navigate through documents at any direction at varying speeds. The navigation tool is preferably transparent to prevent obscuring the text of the underlying document. Accordingly, the navigational tool does not take up additional screen real estate. The GUI of the present invention may be especially useful in portable electronic devices with small displays.

Claims

1. A method of activating functions responsive to a user input, comprising:

providing a manipulable area portion in a physical viewing area, said manipulable area portion having at least one manipulation function associated therewith;

displaying a representation of a control tool overlaying the manipulable area portion, said control tool having at least one control tool function associated therewith;

receiving a user input to the physical viewing area corresponding to the manipulable area portion and the representation of the control tool;

determining if the user input selects the control tool; and

activating the at least one manipulation function when the user input does not select the control tool or permitting the at least one control tool function to be activated when the user input does select the control tool.

2. The method of claim 1, wherein the at least one control tool function includes a function of changing a display of information in the manipulable area portion, the method further including:

after at least one control tool function is permitted to be activated, receiving a subsequent user input selecting a predetermined portion of the control tool; and

activating the function of changing a display of information in response to the subsequent user input.

3. The method of claim 2, wherein the function of changing a display of information includes shifting information in the manipulable area portion.

4. The method of claim 3, wherein the shifting includes scrolling.

5. The method of claim 3, wherein the shifting includes jumping.

6. The method of claim 2, wherein the function of changing a display of information includes control of the speed of the change of the display of information based on the subsequent user input.

7. The method of claim 2, wherein the changing includes displaying a different one of a plurality of pages of information.

8. The method of claim 1, wherein the displaying a representation of the control tool includes displaying arrows indicating direction.

9. The method of claim 1, wherein the information displayed in the manipulable area portion includes a portion of a document and wherein the at least one control tool function includes a function related to the document.

10. The method of claim 1, wherein the displaying the representation of the control tool includes displaying a virtually transparent representation of the control tool.

11. The method of claim 1, wherein the displaying the representation of the control tool includes displaying an opaque representation of the control tool.

12. The method according to claim 1, wherein the at least one manipulation function includes an editing function for a document.

13. An apparatus for activating functions responsive to a user input, comprising:

means for providing a manipulable area portion in a physical viewing area, said manipulable area portion having at least one manipulation function associated therewith;

means for displaying a representation of a control tool overlaying the manipulable area portion, said control tool having at least one control tool function associated therewith;

means for receiving a user input to the physical viewing area corresponding to the manipulable area portion and the representation of the control tool;

means for determining if the user input selects the control tool; and

means for activating the at least one manipulation function when the user input does not select the control tool or permitting the at least one control tool function to be activated when the user input does select the control tool.

14. The apparatus of claim 13, wherein the at least one control tool function includes a function of changing a display of information in the manipulable area portion, the apparatus further including:

means for receiving a subsequent user input selecting a predetermined portion of the control tool, after at least one control tool function is permitted to be activated, and

means for activating the function of changing a display of information in response to the subsequent user input.

15. The apparatus of claim 14, wherein the function of changing a display of information includes shifting information in the manipulable area portion.

16. The apparatus of claim 15, wherein the shifting includes scrolling.

17. The apparatus of claim 15, wherein the shifting includes jumping.

18. The apparatus of claim 14, wherein the function of changing a display of information includes control of the speed of the change of the display of information based on the subsequent user input.

19. The apparatus of claim 14, wherein the changing includes displaying a different one of a plurality of pages of information.

20. The apparatus of claim 13, wherein the means for displaying a representation of the control tool includes displaying arrows indicating direction.

21. The apparatus of claim 13, wherein the information displayed in the manipulable area portion includes a portion of a document, and wherein the at least one control tool function includes a function related to the document.

22. The apparatus of claim 13, wherein the means for displaying the representation of the control tool includes displaying a virtually transparent representation of the control tool.

23. The apparatus of claim 13, wherein the means for displaying the representation of the control tool includes displaying an opaque representation of the control tool.

24. The apparatus according to claim 13, wherein the at least one manipulation function includes an editing function for a document.
