Abstract: A display apparatus includes a display, an input module receiving a user input, a processor is configured to display a user interface (UI) including a first object and a second object on the display, receives a user input to select the second object when the first object is selected as a currently selected object, select the second object as the currently selected object based on the received user input in a first direction and display a third object corresponding to the selected second object on the display. The processor is configured to move the third object in a second direction when the second object is selected as the currently selected object in the first direction.

Abstract: An electronic device is provided. The electronic device includes a first interface for connection to a first external device, a second interface for connection to a second external device, a display, a memory, and a processor. The memory stores instructions that, when executed, cause the processor to receive a first source input from the first external device through the first interface, output a first screen corresponding to the first source input on the display, if a request for switching from the first interface to the second interface is received, output a second screen related to switching to the second external device on the display, and if a first time point at which a second source input is received from the second external device through the second interface comes, output a third screen corresponding to the second source input on the display.

Abstract: A display apparatus includes a display, a sensor configured to sense a user, and a processor configured to control, based on the sensed values of the sensor, the display to operate in one mode among a first mode for outputting information-providing content on the display, a second mode for providing a mirror function with the display, and a third mode for providing UI screen in which user interaction is performed.
