Device and method of running multiple operating systems and presenting multiple operation screens
A device configured to execute a plurality of operating systems, including a display configured to display a screen corresponding to an active operating system among the plurality of operating systems; and a controller configured to control the display to display an operation screen of the active operating system on the display when the active operating system is activated and to display an operation screen of a secondary operating system on the display when the device receives a user input according to a predetermined interface for switching from the active operating system to the secondary operating system.
1. A device configured to execute a plurality of operating systems, the device comprising:
a display; and
a processor configured to:
control the display to display an operation screen of a first operating system when the first operating system is activated;
based on receiving a first user input tracing an outline on the display, control to activate a second operating system;
control the display to display the operation screen of the first operating system on a first display region of the display and to display the operation screen of the second operating system on a second display region of the display, the second display region being defined by a size of the outline and a location of the outline; and
based on receiving a second user input, control the display to change at least one of a size of the second display region and a location of the second display region,
wherein a signal designating user input received on the first display region and a signal designating user input received on the second display region, are filtered from the first operating system.
2. The device of claim 1 , wherein the processor is configured to control the display to increase or decrease a size of the first display region or a size of the second display region in accordance with a predetermined input signal.
3. The device of claim 1 , wherein the processor is further configured to control to copy an object from the first display region and display the copied object on the second display region, in response to a third user input.
4. The device of claim 1 , wherein the processor is further configured to set an interface for switching from the first operating system to the second operating system according to a selection input of a user from among interfaces for switching the plurality of operating systems.
5. The device of claim 4 , wherein, in response to receiving a user input according to the interface for switching from the first operating system to the second operating system, the processor is further configured to control the first operating system to be in an inactive state and to change a state of the second operating system to an active state.
6. A method of executing a plurality of operating systems in a device configured to execute the plurality of operating systems, the method comprising:
controlling a display to display an operation screen of a first operating system when the first operating system is activated;
based on receiving a first user input tracing an outline on the display, controlling to activate a second operating system;
controlling the display to display the operation screen of the first operating system on a first display region of the display and to display the operation screen of the second operating system on a second display region of the display, the second display region being defined by a size of the outline and a location of the outline; and
based on receiving a second user input, controlling the display to change at least one of a size of the second display region and a location of the second display region,
wherein a signal designating user input received on the first display region and a signal designating user input received on the second display region, are filtered from the first operating system.
7. The method of claim 6 , further comprising increasing or decreasing at least one among a size of the first display region or a size of the second display region in accordance with a predetermined input signal.
8. The method of claim 6 , further comprising:
in response to a third user input, controlling to copy an object from the first display region and display the copied object on the second display region.
9. The method of claim 6 , further comprising setting an interface for switching from the first operating system to the second operating system according to a selection input of a user from among interfaces for switching between the plurality of operating systems.
10. The method of claim 9 , further comprising controlling the first operating system to be in an inactive state and changing a state of the second operating system to an active state in response to receiving a user input according to the interface for switching from the first operating system to the second operating system.
11. A non-transitory computer-readable recording medium having embodied thereon a computer program for executing a method comprising:
controlling a display to display an operation screen of a first operating system when the first operating system is activated;
based on receiving a first user input tracing an outline on the display, controlling to activate a second operating system;
controlling the display to display the operation screen of the first operating system on a first display region of the display and to display the operation screen of the second operating system on a second display region of the display, the second display region being defined by a size of the outline and a location of the outline; and
based on receiving a second user input, controlling the display to change at least one of a size of the second display region and a location of the second display region,
wherein a signal designating user input received on the first display region and a signal designating user input received on the second display region, are filtered from the first operating system.
