Abstract

An electronic device can be enhanced to enable its user to navigate about and view, on the device'"'"'s display, different portions of a page or document while the device remains in a zoomed-in mode that magnifies the portion of the document that the device is currently displaying. Upon entering the zoomed-in mode, the device can magnify a portion of the document on the display. While in this mode, the device can react to user-produced gestures in a manner that is different to the manner in which the device would react to the same gestures otherwise. Responsive to user-produced gestures while in the zoomed-in mode, the device can navigate to other portions of the document while remaining in the zoomed-in mode, so that those other portions are also presented magnified. The device'"'"'s user is not forced to first zoom-out from one document portion in order to zoom-in on another document portion.

Claims

1. A method comprising:

in an electronic device adapted to display pages and to receive gestures, each page comprising objects and characterized by a page model relating objects;

displaying a first object;

receiving a gesture;

classifying the received gesture as a first gesture type or a second gesture type;

for a gesture of the first gesture type, continuing to display the first object;

for a gesture of the second gesture type;

determining a second object to display based on the received gesture and the page model; and

displaying the determined second object.

2. The method of claim 1 wherein:

continuing to display the first object comprises inhibiting the effect of the received gesture on at least one aspect of displaying the first object.

3. The method of claim 2 wherein:

inhibiting the effect of the received gesture on at least one aspect of displaying the first object comprises inhibiting horizontal scrolling.

4. The method of claim 3 wherein:

displaying a first object comprises displaying the first object zoomed to the width of the first object, with no vertical object-to-display offset.

5. The method of claim 1 wherein:

displaying the determined second object comprises displaying the determined second object zoomed to the width of the second object, with no vertical object-to-display offset.

6. The method of claim 1, wherein:

the received gesture is characterized by gesture attributes; and

classifying the received gesture is based on a weighted vector of at least one gesture attribute.

7. The method of claim 6, wherein:

the received gesture is a single finger gesture characterized by attributes comprising gesture origin, gesture length, gesture time duration, and gesture direction.

8. A computer-readable storage memory storing particular instructions which, when executed by one or more processors, cause the one or more processors to perform specified operations, the particular instructions comprising:

instructions to cause a device to enter a zoomed-in mode in response to detecting particular user input while presenting an unmagnified view of a document;

instructions to cause the device to present a first magnified portion of the document while the device remains in the zoomed-in mode;

instructions to cause the device to present a second magnified portion of the document in response to detecting a user gesture having a particular gesture type while the device remains in the zoomed-in mode;

instructions to cause the device to perform, in response to detection of a gesture of the particular gesture type while the device is not in the zoomed-in mode, a set of actions that is different from a set of actions that the device performs in response to detection of any gesture of the particular gesture type while the device is in the zoomed-in mode;

wherein the first magnified portion is a different portion of the document than the second magnified portion.

9. The computer-readable storage memory of claim 8, wherein the instructions to cause the device to present the second magnified portion cause the device to present the second magnified portion without presenting the unmagnified view of the document in between presentations of the first magnified portion and the second magnified portion.

10. The computer-readable storage memory of claim 8, wherein the instructions to cause the device to present the second magnified portion cause the device to present a portion of the document that immediately precedes or immediately follows the first magnified portion within a navigational flow of the document.

11. The computer-readable storage memory of claim 8, wherein the first magnified portion is at least a part of a first column of a multi-column document;

wherein the second magnified portion is at least a part of a second column of the multi-column document;

wherein the first magnified portion does not include any of the second column;

wherein the second magnified portion does not include any of the first column; and

wherein the instructions to cause the device to present the second magnified portion cause the device to present a top of the second column after a bottom of the first column was being presented when the gesture of the particular gesture type was detected.

12. The computer-readable storage memory of claim 8, wherein the instructions to cause the device to present the second magnified portion cause the device to adjust a magnification of the view to an extent that causes a width of the second magnified portion to span a width of the device'"'"'s display.

13. The computer-readable storage memory of claim 8, wherein the instructions to cause the device to present the second magnified portion cause the device to adjust a magnification of the view to an extent that causes a height of the second magnified portion to span a height of the device'"'"'s display.

14. A device comprising:

a display adapted for displaying a page, the page comprising objects and characterized by a page model relating objects;

a touch sensitive surface adapted for receiving gesture input;

a data processing system, and

a computer program product comprising;

at least one computer-readable memory storing program code executable by the data processing system;

the program code comprising instructions that when executed by the data processing system are operable for;

displaying a first object on a display of the electronic device;

receiving a gesture on the electronic device;

classifying the received gesture as a first gesture type or a second gesture type;

for a gesture of the first gesture type, continuing to display the first object on the display;

for a gesture of the second gesture type;

determining a second object based on the received gesture and the page model; and

displaying the determined second object on the display.

15. The device of claim 15 wherein:

continuing to display the first object comprises inhibiting the effect of the received gesture on at least one aspect of displaying the first object.

16. The device of claim 15 wherein:

inhibiting the effect of the received gesture on at least one aspect of displaying the first object comprises inhibiting horizontal scrolling.

17. The device of claim 16 wherein:

displaying a first object comprises displaying the first object zoomed to the width of the first object, with no vertical object-to-display offset.

18. The device of claim 15 wherein:

displaying the determined second object comprises displaying the determined second object zoomed to the width of the second object, with no vertical object-to-display offset.

19. The device of claim 15, wherein:

the received gesture is characterized by gesture attributes; and

classifying the received gesture is based on a weighted vector of at least one gesture attribute.

20. The device of claim 19, wherein:

the received gesture is a single finger gesture characterized by attributes comprising gesture origin, gesture length, gesture time duration, and gesture direction.
