Abstract

The application relates to computing devices, computer readable media, and methods for navigating content via a touch screen display having dedicated zones for accepting zooming instructions and scrolling and/or panning commands.

Claims

a touch screen display serving as a primary display for the computing device;

a screen monitor for detecting contact of a pointing tool with the touch screen display and for detecting the location of the contact on the touch screen; and

a user interface module for initiating a zoom command in response to the screen monitor detecting contact in a first input region of the touch screen display, and for initiating one of a scroll command and a pan command in response to the screen monitor detecting contact with a second input region of the touch screen display.

2. The computing device of claim 1, wherein the first input region comprises a zone corresponding to a zoom-in command and a zone corresponding to a zoom-out command.

3. The computing device of claim 1, wherein the second input region comprises a zone corresponding to a scroll-up command and a zone corresponding to a scroll-down command.

4. The computing device of claim 1, wherein the second input region comprises a zone corresponding to a pan-left command and a zone corresponding to a pan-right command.

5. The computing device of claim 1, wherein the screen monitor detects a direction of movement of the pointing tool contacting the touch screen display and assigns a direction parameter to the contact based on the detected direction.

6. The computing device of claim 5, wherein the user interface module initiates one of a zoom-in command and a zoom-out command based on the direction parameter assigned to the contact.

7. The computing device of claim 5, wherein the user interface module initiates one of a scroll-up command and a scroll-down command based on the direction parameter assigned to the contact.

8. The computing device of claim 5, wherein the user interface module initiates one of a pan-left command and a pan-right command based on the direction parameter assigned to the contact.

9. The computing device of claim 1, wherein the interface module detects and initiates a set of commands from a set of commands consisting only of zoom-in, zoom-out, scroll-up, and scroll-down.

10. The computing device of claim 1, wherein the interface module detects and initiates a set of commands from a set of commands consisting only of zoom-in, zoom-out, pan-left, and pan-right.

11. The computing device of claim 1, wherein the interface module detects and initiates a set of commands from a set of commands consisting only of zoom-in, zoom-out, scroll-up, scroll-down, pan-left, and pan-right.

12. The computing device of claim 1, comprising a second input device distinct from the touch screen display.

13. The computing device of claim 12, wherein the second input device comprises a keypad.

14. A computing device comprising:

a touch screen display serving as a primary display for the computing device;

a screen monitor for detecting contact of a pointing tool with the touch screen display and for detecting the location of the contact on the touch screen;

a user interface module for initiating a zoom command in response to the screen monitor detecting contact in a first input region of the touch screen display, for initiating a scroll command in response to the screen monitor detecting contact with a second input region of the touch screen display, and for initiating a pan command in response to the screen monitor detecting contact with a third input region of the touch screen display.

15. A computer readable medium encoding instructions for performing a method of document navigation, the method comprising:

logically dividing a touch sensitive display into a first input region for receiving zoom commands and a second input region for receiving one of scroll and pan commands;

detecting contact of a pointing tool within one of the first and second input regions on the touch sensitive display screen; and

initiating one of zoom command, a scroll command, and a pan command based on the input region in which the contact was detected.

16. The computer readable medium of claim 15, comprising instructions for dividing the first input region into a zone corresponding to a zoom-in command and a zone corresponding to a zoom-out command.

17. The computer readable medium of claim 15, comprising instructions for dividing the second input region into a zone corresponding to a scroll-up command and a zone corresponding to a scroll-down command.

18. The computer readable medium of claim 15, comprising instructions for dividing the second input region into a zone corresponding to a pan-left command and a zone corresponding to a pan-right command.

19. The computer readable medium of claim 15, comprising instructions for detecting a direction of movement of the pointing tool contacting the touch screen display and for assigning a direction parameter to the contact based on the detected direction.

20. The computer readable medium of claim 19, comprising instructions for initiating one of a zoom-in command and a zoom-out command based on the direction parameter assigned to the contact.

21. The computer readable medium of claim 19, comprising instructions for initiating one of a scroll-up command and a scroll-down command based on the direction parameter assigned to the contact.

22. The computer readable medium of claim 19, comprising instructions for initiating one of a pan-left command and a pan-right command based on the direction parameter assigned to the contact.

23. The computer readable medium of claim 15, comprising instructions for detecting and initiating a set of commands from a set of commands consisting only of zoom-in, zoom-out, scroll-up, and scroll-down.

24. The computer readable medium of claim 15, comprising instructions for detecting and initiating a set of commands from a set of commands consisting only of zoom-in, zoom-out, pan-left, and pan-right.

25. The computer readable medium of claim 15, comprising instructions for detecting and initiating a set of commands from a set of commands consisting only of zoom-in, zoom-out, scroll-up, scroll-down, pan-left, and pan-right.

26. A computer readable medium encoding instructions for performing a method of document navigation, the method comprising:

logically dividing a touch sensitive display into a first input region for receiving zoom commands, a second input region for receiving a scroll, and a third input region for receiving a pan command;

detecting contact of a pointing tool within one of the first, second, and third input regions on the touch sensitive display screen; and

initiating one of zoom command, a scroll command, and a pan command based on the input region in which the contact was detected.

27. A method of document navigation, the method comprising:

logically dividing a touch sensitive display into a first input region for receiving zoom commands and a second input region for receiving one of scroll and pan commands;

detecting contact of a pointing tool within one of the first and second input regions on the touch sensitive display screen; and

initiating one of zoom command, a scroll command, and a pan command based on the input region in which the contact was detected.
