Abstract

The present invention relates to an electronic device and a method of controlling the same. An electronic device according to an embodiment of the present invention converts the state of a page displayed on a touchscreen to a standby state through rear input and cancels the standby state upon release of the rear input, thereby providing a page corresponding to a desired time when the rear input is released.

Claims

1. An electronic device, comprising:

a body;

a touchscreen at a first surface of the body;

a rear input unit at a second surface of the body; and

a controller configured to;

receive a first input at the rear input unit while a first page is displayed on the touchscreen,

store the first page in a standby state in response to the first input,

receive a second input at the touch screen,

execute a function corresponding to the second input while maintaining the standby state, and

display the first page stored in the standby state on the touchscreen upon release of the first input at the rear input unit.

2. The electronic device of claim 1, wherein in response to the first input at the rear input unit, the controller displays, on the touchscreen, a first thumbnail corresponding to the first page.

3. The electronic device of claim 2, wherein the second input is an input to change the page displayed on the touchscreen,

wherein the controller displays a second thumbnail corresponding to a second page along with the first thumbnail on the touchscreen when a predetermined input is received while the second page is displayed on the touchscreen.

4. The electronic device of claim 3, wherein the predetermined input is one of:

an input at a soft key on the touchscreen,

an input at a hard key on the body, and

a touch input at the rear input unit when the rear input unit is a touch panel, the touch input being discriminated from the first input.

5. The electronic device of claim 2, wherein in response to release of the first input at the rear input unit, the controller removes the first thumbnail displayed on the touchscreen.

6. The electronic device of claim 1, wherein when a plurality of pages are stored in the standby state, the controller displays, on a thumbnail tray on the touchscreen, a plurality of thumbnails respectively corresponding to the plurality of pages.

7. The electronic device of claim 6, wherein the controller controls display of a page corresponding to a thumbnail on the thumbnail tray based on a touch pattern applied at the thumbnail.

8. The electronic device of claim 1, wherein the first page is one of a webpage and a page to edit an image.

9. The electronic device of claim 1, wherein the second input is a drag input applied to a submenu corresponding to the first page,

wherein in response to the drag input while maintaining display of the first page, the controller displays a slidable layer, and the controller displays information related to the submenu on the slidable layer.

10. The electronic device of claim 1, wherein the second input is a predetermined input with respect to one of a plurality of components of the first page, wherein the controller separates a selected component from the first page and displays the separated component as a movable floating window.

11. The electronic device of claim 1, wherein the first input includes a touch-and-drag input at the rear input unit,

wherein in response to the first input, a back portion of the first page is displayed on the touchscreen, and the displayed back portion of the first page to receive a handwriting input.

12. The electronic device of claim 1, wherein the first page includes a preview image captured by a camera, and the second input includes an input to capture an image, and

wherein in response to the second input, the controller displays, on the preview image, a thumbnail corresponding to a captured image.

13. The electronic device of claim 1, wherein the controller configured to display an indicator on the touchscreen to indicate the receiving of the first input at the rear input unit.

14. An electronic device, comprising:

a body;

a touchscreen at a first surface of the body;

a rear input unit at a second surface of the body; and

a controller configured to;

receive a first input at the rear input unit while a page having at least one item is displayed on the touchscreen,

display, on the touchscreen, a layer having a size that varies according to the first input while the page having at least one item is displayed on the touchscreen,

receive a second input to select at least one item while maintaining the first input, and

display, in response to the second input, the selected at least one item on the displayed layer.

15. The electronic device of claim 14, wherein in response to release of the first input, the controller generates a layer including the selected item and displays the layer on the touchscreen.

16. The electronic device of claim 14, wherein the rear input unit includes a touch panel, and the first input includes a multi-touch input at the touch panel,

wherein the controller displays a plurality of layers respectively corresponding to the multi-touch input on the touchscreen.

17. A method of controlling an electronic device, comprising:

displaying a first page on a touchscreen at a first surface of a body of the electronic device;

receiving a first input at a rear input unit at a second surface of the body;

storing, in response to the first input, the first page in a standby state;

receiving a second input at the touchscreen while maintaining the standby state;

executing a function corresponding to the second input; and

displaying the first page in the standby state on the touchscreen upon release of the first input.

18. The method of claim 17, wherein the first page is one of a webpage, a preview image according to execution of a camera application, an image editing screen, at least one image and a content playlist.

19. The method of claim 17, wherein the first input is one of a touch input at the rear input unit, a touch-and-drag input and a multi-touch input.

20. The method of claim 17, further comprising displaying a first thumbnail corresponding to the first page on the touchscreen.
