Abstract

A method for multitasking in an electronic device is provided, the method including: displaying a first one of a plurality of function execution screens as a top layer screen on a display unit of the electronic device; receiving, by the electronic device, a first touch input; and displaying, in response to the first touch input, a first layer separation object for causing a second one of the plurality of function execution screens to be at least partially displayed as the top layer screen on the display unit; wherein the first layer separation object is displayed concurrently with the first function execution screen.

First claim

What is claimed is:

1. A method for operating an electronic device, the method comprising:
displaying a first execution screen of a first application as a top layer screen on a display;
in response to receiving a first touch input at a first edge region of the display corresponding to a first edge of the display, simultaneously displaying a first layer separation object and the first execution screen on the display;
in response to receiving a second touch input on the first layer separation object, simultaneously displaying a portion of the first execution screen, a portion of a second execution screen of a second application, the first layer separation object, and a second layer separation object on the display; and
in response to receiving a third touch input from the second layer separation object to a second edge region opposite to the first edge region, removing an entirety of the first execution screen, the first layer separation object and the second layer separation object from the display to display the second execution screen as the top layer screen on the display,
wherein the first layer separation object includes at least a first line corresponding to an edge of the first execution screen and a second line corresponding to an edge of the portion of the second execution screen, and
wherein, during or after receiving the first touch input but before receiving the second touch input, the first line and the second line are parallel to the first edge of the display so as to display a shape in which the first execution screen is stacked over the second execution screen.

2. The method of claim 1 , further comprising:
receiving a fourth touch input from the first layer separation object to the second layer separation object before receiving the third touch input; and
in response to receiving the fourth touch input, replacing the portion of the second execution screen entirely with a portion of a third execution screen of a third application,
wherein the third execution screen is displayed on the display as the top layer screen in place of the second execution screen in response to receiving the third touch input, and
wherein the second touch input is received after reception of the first touch input and after displaying the first layer separation object and the first execution screen.

3. The method of claim 2 , further comprising:
in response to receiving a fifth touch input from the second layer separation object to the first edge region, removing the third execution screen, the first layer separation object and the second layer separation object from the display, and displaying the first execution screen as the top layer screen on the display.

4. The method of claim 2 , wherein the second layer separation object includes lines corresponding to the first execution screen and the second execution screen, respectively.

5. The method of claim 1 , wherein the second touch input is a drag movement beginning from the first touch input.

6. The method of claim 1 , wherein the first layer separation object includes a plurality of lines extending along a length of the display, and each of the lines corresponds to an executing application other than the first application.

7. The method of claim 1 , further comprising arranging labels on the first layer separation object, and
wherein each of the labels indicates identification information of an execution screen that is not displayed as the top layer screen.

8. The method of claim 1 , wherein the simultaneously displaying of the first layer separation object and the first execution screen comprises one of:
displaying the first layer separation object as an overlay on the first execution screen; and
resizing the first execution screen so as to free space to accommodate the first layer separation object.

9. The method of claim 1 , further comprising:
when no touch input is received for a preset time after receiving the second touch input, removing the second execution screen, the first layer separation object, and the second layer separation object, and displaying the first execution screen as the top layer screen in full screen format.

10. An electronic device comprising:
a display having a display panel and a touch panel;
a processor, operatively coupled to the display and configured to:
display a first execution screen of a first application as a top layer screen on the display;
in response to receiving a first touch input at a first edge region of the display corresponding to a first edge of the display, simultaneously display a first layer separation object and the first execution screen on the display;
in response to receiving a second touch input on the first layer separation object, simultaneously display a portion of the first execution screen, a portion of a second execution screen of a second application, the first layer separation object, and a second layer separation object on the display; and
in response to receiving a third touch input from the second layer separation object to a second edge region opposite to the first edge region, remove an entirety of the first execution screen, the first layer separation object and the second layer separation object from the display to display the second execution screen as the top layer screen on the display,

wherein the first layer separation object includes at least a first line corresponding to an edge of the first execution screen and a second line corresponding to an edge of the portion of the second execution screen, and
wherein, during or after receiving the first touch input but before receiving the second touch input, the first line and the second line are parallel to the first edge of the display so as to display a shape in which the first execution screen is stacked over the second execution screen.

11. The electronic device of claim 10 , wherein the processor is further configured to:
receive a fourth touch input from the first layer separation object to the second layer separation object before receiving the third touch input; and
in response to receiving the fourth touch input, replace the portion of the second execution screen entirely with a portion of a third execution screen of a third application,
wherein the third execution screen is displayed on the display as the top layer screen in place of the second execution screen in response to receiving the third touch input, and
wherein the second touch input is received after reception of the first touch input and after displaying the first layer separation object and the first execution screen.

12. The electronic device of claim 11 , wherein the processor is further configured to:
in response to receiving a fifth touch input from the second layer separation object to the first edge region, remove the third execution screen, the first layer separation object and the second layer separation object from the display, and display the first execution screen as the top layer screen on the display.

13. The electronic device of claim 11 , wherein the second layer separation object includes lines corresponding to the first execution screen and the second execution screen, respectively.

14. The electronic device of claim 10 , wherein the second touch input is a drag movement beginning from the first touch input.

15. The electronic device of claim 10 , wherein the first layer separation object includes a plurality of lines extending along a length of the display, and each of the lines corresponds to an executing application other than the first application.

16. The electronic device of claim 10 , wherein the process
