Abstract

A method includes entering, by a portable electronic device, a low-power condition and while in the low-power condition, detecting an input. In response to detecting the input, a cover image is displayed. An application image is progressively revealed along with movement of a gesture while reducing display of the cover image.

Claims

1. A method comprising:

entering, by a portable electronic device, a low-power condition after displaying an application image on a display;

while in the low-power condition, detecting an input;

in response to detecting the input, displaying a cover image;

along with movement of a detected gesture, progressively revealing the application image while reducing display of the cover image.

2. The method of claim 1, wherein progressively revealing comprises progressively revealing the application image from a first end of the application image toward a second end of the application image opposite the first end as the gesture continues.

3. The method of claim 1, wherein progressively revealing comprises revealing the application image from a first end of the application image and gradually revealing more of the application image toward a second end of the application image opposite the first end as the gesture moves from the first end toward the second end.

4. The method of claim 3, wherein the first end extends across the display from a first edge of the display to a second edge of the display opposite the first side and the second end extends across the display from the first edge to the second edge.

5. The method of claim 4, wherein the gesture begins near the first end.

6. The method of claim 1, wherein the application image is progressively revealed as the gesture moves in a first direction, and the application image is progressively covered by gradually displaying more of the cover image as the gesture moves in a second direction opposite the first direction.

7. The method of claim 1, further comprising detecting a change in direction of the gesture and progressively covering the application image along with movement of the gesture.

8. The method of claim 7, further comprising, when the gesture meets a threshold, discontinuing display of the cover image and returning to the low-power condition.

9. The method of claim 1, wherein progressively revealing comprises gradually increasing a size of an area of the application image that is displayed while gradually decreasing a size of an area of the cover image that is displayed.

10. The method of claim 1, further comprising, when the gesture meets a threshold, displaying the application image and discontinuing display of the cover image.

11. The method of claim 1, wherein an application is running in a state when the low-power condition is entered, further comprising continuing operation of the application at the state when the gesture meets a threshold.

12. The method of claim 1, when the gesture ends before meeting a threshold, discontinuing display of the cover image and returning to the low-power condition.

13. The method of claim 1, further comprising identifying one or more informational icons and displaying the informational icons when the cover image is displayed.

14. The method of claim 1, wherein the application image revealed unevenly across the display, wherein more of the application image is revealed near a current touch location than to a side of the current touch location.

15. The method of claim 1, wherein no information is displayed on the display during the low-power condition.

16. The method of claim 1, wherein the input is part of the gesture.

17. A computer-readable device having computer-readable code executable by at least one processor of a portable electronic device to perform the method of claim 1.

18. An electronic device comprising a processor configured to perform the method of claim 1.

19. A method comprising:

entering, by a portable electronic device, a low-power condition;

while in the low-power condition, detecting a gesture on the touch-sensitive display and displaying a cover image in response to the detecting;

while gesture continues;

when the gesture moves in a first direction, progressively revealing an application image from a first end of the application image toward a second end of the application image opposite the first end along with movement of the gesture;

when the gesture moves in a second direction, progressively covering the application image with the cover image from the second end toward the first end along with movement of the gesture.

20. The method of claim 19, wherein progressively covering the application image comprises displaying less of the application image and more of the cover image.

21. The method of claim 19, wherein progressively revealing comprising gradually reducing display of the cover image while gradually increasing display of the application image.

22. A method comprising:

entering, by a portable electronic device, a low-power condition after displaying an application image on a display;

while in the low-power condition, detecting a gesture;

in response to detecting the gesture, displaying a cover image;

along with movement of the gesture, progressively revealing the application image while reducing display of the cover image.
