Abstract

There is disclosed a method and apparatus for a user interface for page view zooming. The method comprises generating a default user interface including an electronic document. The method further includes receiving touchdown and hold data indicating that a user has interacted with a portion of the electronic document and beginning a continuous zoom process for that portion of the electronic document. The method further includes halting the zoom process once a user has released the touch over the portion of the electronic document and displaying the magnified document on the user interface. The method employs a similar operation to enable a de-zooming operation.

Claims

1. A method for providing a user interface comprising:

generating a visual representation of an electronic document on a user interface, generated on a touchscreen display, the electronic document shown in a default magnification level;

receiving touchdown data indicating that a touch has been received from a user on the touchscreen display over the electronic document and hold data indicating that the user has held the touch for a predetermined period of time over the electronic document;

altering the visual representation in response to the touchdown data and the hold data such that a current magnification level of the electronic document is increased for the duration of the touch, the current magnification level centered on a portion of the electronic document over which the touch is positioned;

receiving release data indicating that the user has released the touch;

halting increase of the current magnification level in response to the release data; and

regenerating the visual representation to show a zoomed portion of the electronic document on the user interface, the zoomed portion being the visual representation of the portion of the electronic document at the current magnification level.

2. The method of claim 1 further comprising:

receiving double-touch data indicating that a second touch and a third touch have been received from the user within a second predetermined period of time; and

returning the visual representation of the electronic document to the default magnification level in response to the double-touch data.

3. The method of claim 1 further comprising altering the visual representation of the zoomed electronic document to incorporate a plurality of interactive elements superimposed over the zoomed electronic document.

4. The method of claim 3 wherein the plurality of interactive elements include touch-sensitive user interface components that, when interacted with by a user, cause the zoomed electronic document to rotate relative to the user interface, cause the zoomed electronic document to return to the default magnification level, and cause the portion of the electronic document to be deleted.

5. The method of claim 1 further comprising:

receiving double-touch data indicating that a second touch and a third touch have been received from the user within a second predetermined period of time; and

receiving second hold data indicating that the user has held the third touch for a predetermined period of time over the electronic document;

altering the visual representation in response to the double-touch data and the second hold data such that the current magnification level of the electronic document is decreased for the duration of the third touch, the current magnification level centered on a second portion of the electronic document over which the third touch is positioned;

receiving second release data indicating that the user has released the third touch;

halting decrease of the current magnification level in response to the second release data; and

regenerating the visual representation to show a de-zoomed portion of the electronic document on the user interface, the de-zoomed portion being the visual representation of the second portion of the electronic document at the current magnification level.

6. The method of claim 1 further comprising:

receiving maximum zoom data indicating that the current magnification level has reached a predetermined maximum;

halting increase of the current magnification level in response to the maximum zoom data; and

regenerating the visual representation to show a zoomed portion of the electronic document on the user interface, the zoomed portion being the visual representation of the portion of the electronic document at the current magnification level.

7. A multifunction peripheral, including a processor and associated memory, the multifunction peripheral including software that when executed by the processor causes the multifunction peripheral to:

generate a visual representation of an electronic document on a user interface generated on a touchscreen display, the electronic document shown in a default magnification level;

receive touchdown data indicating that a touch has been received from a user on the touchscreen display over the electronic document and hold data indicating that the user has held the touch for a predetermined period of time over the electronic document;

alter the visual representation in response to the touchdown data and the hold data such that a current magnification level of the electronic document is increased for the duration of the touch, the current magnification level centered on a portion of the electronic document over which the touch is positioned;

receive release data indicating that the user has released the touch;

halt increase of the current magnification level in response to the release data; and

regenerate the visual representation to show a zoomed portion of the electronic document on the user interface, the zoomed portion being the visual representation of the portion of the electronic document at the current magnification level.

8. The multifunction peripheral of claim 7 wherein the software will further cause the multifunction peripheral to:

receive double-touch data indicating that a second touch and a third touch have been received from the user within a second predetermined period of time; and

return the visual representation of the electronic document to the default magnification level in response to the double-touch data.

9. The multifunction peripheral of claim 7 wherein the software will further cause the multifunction peripheral to alter the visual representation of the zoomed electronic document to incorporate a plurality of interactive elements superimposed over the zoomed electronic document.

10. The multifunction peripheral of claim 9 wherein the plurality of interactive elements include touch-sensitive user interface components that, when interacted with by a user, cause the zoomed electronic document to rotate relative to the user interface, cause the zoomed electronic document to return to the default magnification level, and cause the portion of the electronic document to be deleted.

11. The multifunction peripheral of claim 7 wherein the software will further cause the multifunction peripheral to:

receive double-touch data indicating that a second touch and a third touch have been received from the user within a second predetermined period of time; and

receive second hold data indicating that the user has held the third touch for a predetermined period of time over the electronic document;

alter the visual representation in response to the double-touch data and the second hold data such that the current magnification level of the electronic document is decreased for the duration of the third touch, the current magnification level centered on a second portion of the electronic document over which the third touch is positioned;

receive second release data indicating that the user has released the third touch;

halt decrease of the current magnification level in response to the second release data; and

regenerate the visual representation to show a de-zoomed portion of the electronic document on the user interface, the de-zoomed portion being the visual representation of the second portion of the electronic document at the current magnification level.

12. The multifunction peripheral of claim 7 wherein the software will further cause the multifunction peripheral to:

receive maximum zoom data indicating that the current magnification level has reached a predetermined maximum;

halt increase of the current magnification level in response to the maximum zoom data; and
