Abstract

Methods and apparatuses are provided for navigating an electronic document. In one implementation, a method includes executing a command associated with a region selected by a tap gesture. In another implementation, a method includes displaying a slider on a slide bar including an expanded part corresponding to a section of the electronic document. The expanded part is disproportionately larger than other parts of the slide bar corresponding to other sections of the electronic document. Methods and apparatuses are provided for activating an element of an electronic document. In one implementation, a method includes activating the element selected by a touch gesture. Methods and apparatuses are provided for controlling a perceived brightness of an electronic document. In one implementation, a method includes displaying a partially opaque graphical object in front of the electronic document. The perceived brightness of the electronic document being based on an opacity of the graphical object.

Claims

1. A computer-implemented method for navigating an electronic document on a portable device, the method comprising:

displaying, by a processor of the portable device, the electronic document on a touch screen of the portable device;

defining a plurality of regions on the touch screen;

displaying, on the touch screen, boundaries of the plurality of regions as an overlay for the electronic document when the electronic document is first displayed on the touch screen;

hiding, by the processor, the boundaries after a predetermined delay;

detecting a tap gesture on the touch screen;

determining a selection of one of the regions based on a location of the tap gesture on the touch screen; and

executing, by the processor of the portable device, a command associated with the selected region.

2. The computer-implemented method of claim 1, wherein the command comprises displaying a next page of the electronic document.

3. The computer-implemented method of claim 1, wherein the command comprises displaying a previous page of the electronic document.

4. The computer-implemented method of claim 1, wherein the command comprises displaying control objects on the touch screen.

5. A computer-implemented method for navigating an electronic document on a terminal, the method comprising:

defining a plurality of regions on a touch screen of the terminal based on a size of the touch screen, the plurality of regions including a left region on the touch screen to navigate the electronic document to a previous page and a right region on the touch screen to navigate the electronic document to a next page;

displaying a first graphical rendition of a page of the electronic document on the touch screen, the first graphical rendition including boundaries of the plurality of the regions;

displaying a second graphical rendition of the page of the electronic document on the touch screen after a predetermined period, the second graphical rendition without the boundaries of the plurality of the regions;

detecting a tap gesture on the touch screen at one of the regions; and

executing, by a processor of the terminal, in response to the detected tap gesture, a command associated with the region at which the tap gesture was detected.

6. The computer-implemented method of claim 5, wherein the executed command displays the next page of the electronic document.

7. The computer-implemented method of claim 5, wherein the executed command displays the previous page of the electronic document.

8. The computer-implemented method of claim 5, wherein:

the plurality of regions further comprise a central region selectable to access a plurality of control objects.

9. The computer-implemented method of claim 8, further comprising:

the executed command displays the plurality of control objects on the touch screen.

10. The computer-implemented method of claim 5, wherein the executed command is user configurable.

11. The computer-implemented method of claim 5, further comprising:

detecting a change in a width of the electronic document displayed on the touch screen; and

redefining, based on the detected change, the boundaries of the regions; and

re-displaying the first graphical rendition of the page of the electronic document on the touch screen, the first graphical rendition including the redefined boundaries of the plurality of the regions.

12. The computer-implemented method of claim 11, wherein the executed command is defined by the terminal.

13. The computer-implemented method of claim 11, wherein detecting the change in the width of the electronic document displayed on the touch screen comprises detecting a change in an orientation of the terminal.

14. A portable electronic device comprising:

a display; and

one or more processors configured to perform acts comprising;

displaying an electronic document on a touch screen of the portable electronic device;

defining a plurality of regions on the touch screen;

displaying boundaries of at least a first region of the plurality of regions as an overlay to the electronic document in response to displaying the electronic document on the touch screen of the portable electronic device;

hiding the boundaries of the first region after a predetermined period of time has elapsed;

detecting a tap gesture on the touch screen;

determining a selection of the first region based on a location of the tap gesture on the touch screen; and

executing, by the one or more processors of the portable electronic device, a command associated with the first region.

15. The portable electronic device of claim 14, wherein the command comprises displaying a next page of the electronic document.

16. The portable electronic device of claim 14, wherein the command comprises displaying a previous page of the electronic document.

17. The portable electronic device of claim 14, wherein the command comprises displaying control objects on the touch screen.

18. A system comprising:

one or more processors; and

one or more computer readable media storing computer-executable instructions that, when executed on the one or more processors, cause the one or more processors to perform acts comprising;

defining a plurality of regions on a touch screen of a terminal displaying an electronic document, the plurality of regions including a left region to navigate the electronic document to a previous page, and a right region to navigate the electronic document to a next page;

associating a command with at least one of the plurality of regions;

displaying a first graphical rendition of a page of the electronic document on the touch screen, the first graphical rendition including boundaries of the plurality of the regions;

displaying a second graphical rendition of the page of the electronic document on the touch screen after a predetermined period has elapsed, the second graphical rendition without the boundaries of the plurality of the regions;

detecting a tap gesture on the touch screen at one of the plurality of regions having an associated command; and

executing, by the one or more processors of the terminal, in response to the detected tap gesture, the command associated with the region at which the tap was detected.

19. The system of claim 18, wherein the executed command displays a next page of the electronic document.

20. The system of claim 18, wherein the executed command displays a previous page of the electronic document.

21. The system of claim 18, wherein:

the plurality of regions further comprise a central region selectable to access a plurality of control objects; and

the executed command displays the plurality of control objects on the touch screen.

22. The system of claim 21, wherein the plurality of control objects are overlaid on the page of the electronic document.

23. The system of claim 22, wherein the page of the electronic document is partially visible through the plurality of control objects.

24. The system of claim 18, further comprising:

detecting a change in a width of the electronic document displayed on the touch screen; and

redefining, based on the detected change, the boundaries of the regions.

25. The system of claim 24, further comprising:

displaying the redefined boundaries of the regions on the touch screen.

26. The system of claim 24, wherein detecting the change in the width of the electronic document displayed on the touch screen comprises detecting a change in an orientation of the terminal.
