First Claim
Patent Images
1. An electronic device, comprising:
- a touchscreen;
a memory; and
a processor electrically connected with the touchscreen and the memory, wherein the memory stores instructions that cause, when executed, the processor to control the electronic device to;
receive a first touch input while a first task execution screen for a first task running on the electronic device is displayed on the touchscreen;
based on receiving the first touch input, display a stack of partially overlaid visual elements on the touchscreen, wherein the visual elements in the stack respectively correspond to a plurality of tasks, including the first task, a visual element corresponding to the first task is on top of the stack, and each visual element includes a task execution screen image and identifier information for identifying the corresponding task;
receive a second touch input for slidably moving one or more of the visual elements in the stack, while the stack is displayed;
receive a third touch input for removing a visual element corresponding to a task from the stack;
based on receiving the third touch input, remove the visual element corresponding to the task from the stack and adjust an interval between two consecutive visual elements of the visual elements remaining in the stack after removing the visual element corresponding to the task;
receive a fourth touch input for selecting a visual element from the stack of partially overlaid visual elements; and
based on receiving the fourth touch input, display, on the touchscreen, a second task execution screen for a second task corresponding to the selected visual element.

Abstract
A method and an electronic device are provided in which, in response to a first user input, a stack of partially overlaid visual elements is displayed in response to the first user input. Each visual element corresponds to an application that is running in the electronic device and includes an index item representing the corresponding application. A second user input for selecting a visual element from the stack of partially overlaid visual elements is received through the touchscreen. An execution screen of an application corresponding to the selected visual element is displayed.

9. A non-transitory computer-readable medium storing instructions that, when executed by a processor of an electronic device, cause the processor to control the electronic device to at least:
-
receive a first touch input while a first task execution screen for a first task running on the electronic device is displayed on a touchscreen of the electronic device; based on receiving the first touch input, display a stack of partially overlaid visual elements on the touchscreen, wherein the visual elements in the stack respectively correspond to a plurality of tasks, including the first task, a visual element corresponding to the first task is on top of the stack, and each visual element includes a task execution screen image and identifier information for identifying the corresponding task; receive a second touch input for slidably moving one or more of the visual elements in the stack, while the stack is displayed; receive a third touch input for removing a visual element corresponding to a task from the stack; based on receiving the third touch input, remove the visual element corresponding to the task from the stack and adjust an interval between two consecutive visual elements of the visual elements remaining in the stack after removing the visual element corresponding to the task; receive a fourth touch input for selecting a visual element from the stack of partially overlaid visual elements; and based on receiving the fourth touch input, display, on the touchscreen, a second task execution screen for a second task corresponding to the selected visual element. - View Dependent Claims (10, 11, 12)
