Implementations use a first device (e.g., an HMD) to provide a CGR environment that augments the input and output capabilities of a second device, e.g., a laptop, smart speaker, etc. In some implementations, the first device communicates with a second device in its proximate physical environment to exchange input or output data. For example, an HMD may capture an image of a physical environment that includes a laptop. The HMD may detect the laptop, send a request the laptop's content, receive content from the laptop (e.g., the content that the laptop is currently displaying and additional content), identify the location of the laptop, and display a virtual object with the received content in the CGR environment on or near the laptop. The size, shape, orientation, or position of the virtual object (e.g., a virtual monitor or monitor extension) may also be configured to provide a better user experience.

A method according to one embodiment includes detecting a first touch event on a touch-sensitive input area of a display, the touch-sensitive input area having groups of virtual ambiguous keys arranged approximately radially about a center point. The method further includes determining a plurality of words based on the detected first touch event, outputting at least two of the determined words to a list on a first portion of the display, and in response to detecting a gesture based second touch event in a predefined area of the touch-sensitive input area, changing the list on the display. The method further includes outputting at least one of the words in the list to a second portion of the display in response to detecting a tap based second touch event in an area selected from the group consisting of: the predefined area and the first portion of the display.

A brightness adjustment method and device and an electronic device are provided. The method comprises: detecting a click of a user on a designated physical key; if the click is detected, displaying a designated panel on a touch sensitive display, wherein the designated panel comprises a brightness adjustment panel of the touch sensitive display; and adjusting the brightness of the touch sensitive display in accordance with a gesture operation of the user on the brightness adjustment panel.

Disclosed is a display device providing a user interface to switch a control object of a pointer from the display device to an external transparent display device. The display device includes a display unit including a first display area, a communication unit to communicate with an external transparent display device including a second display area, and a control unit. The control unit receives a pointer control signal, detects a first area among the first display area overlapped by the external transparent display device, sets a user interface to a position proximate to at least a portion of the edge of the first area, transmits the pointer control signal to the external transparent display device when the pointer overlaps at least a portion of the user interface, and transmits no pointer control signal when the pointer moves into the first area in a path not passing through the user interface.

Disclosed are a mobile device and a method of operating the mobile device. A mobile device according to an embodiment includes a sensing unit configured to determine whether a stylus pen is separated from the mobile device, a communication unit configured to receive a control signal from the stylus pen separated from the mobile device, and a controller configured to operate in a first control mode for performing at least one operation of an application being executed on the mobile device, in response to the control signal.

A method and electronic device are provided for displaying a list of executable applications on a split screen. The electronic device includes a display, a memory, and a processor. The memory stores a history including information indicating split-screen areas in which scenes associated with executed applications are respectively displayed in a split-screen mode. In response to execution of an application, the processor displays a first scene associated with the executed application on the display. In response to receiving a signal for entry into the split-screen mode, the processor identifies a first split-screen area for displaying a reduced scene of the first scene, and identifies second and third split-screen areas obtained by dividing a remaining area of the display, other than the first split-screen area, generates a first list of applications, based on the history, and displays the first list in the second split-screen area.

A method and apparatus for giving a prompt about a touch input operation is disclosed. A method comprises: displaying a graphic user interface (GUI), wherein a touch input operation prompt corresponding to at least one GUI widget is displayed on the GUI; receiving a touch input operation, wherein the received touch input operation is one of the touch input operations that are prompted on the GUI; executing a command represented by the GUI widget corresponding to the received touch input operation. The method and apparatus may give prompts about touch input operations corresponding to GUI widgets when running a GUI, so that users may execute commands represented by those GUI widgets intuitively using touch input operations.

Disclosed is a television including a display body and an interface extension apparatus. The display body includes a shell and a main board provided with a first interface and installed in the shell. The shell is provided with a channel opening. The interface extension apparatus includes a driving module and an interface extension line including a data line and a second interface. The data line is connected between the first interface and the second interface. The driving module is in transmission connection with the data line. The driving module is for driving one end of the interface extension line provided with the second interface to out of the shell through the channel opening, and driving the interface extension line out of the shell to be retracted into the shell through the channel opening. The application also discloses a television control method and a control apparatus.

The present technology relates to a display control device and a display control method each of which is capable of further improving operability. Provided is a display control device including a control unit that displays a plurality of items associated with a display screen, and, in a case where a desired item is selected by a user operation from the plurality of displayed items, displays a selected display screen corresponding to the selected item together with the display screen that is currently displayed, the selected display screen being displayed at a position relative to a display position of the selected item. The present technology is applicable to, for example, a television receiver.

The invention relates to a user interface control device, comprising display; an input key that can be pressed by a user, and a processor configured to register a starting time and a duration of a key press on the input key, wherein the processor is configured to assign a first function to the input key if the duration of the key press is shorter or equal to a threshold time value, and wherein the processor is configured assign a second function to the input key if the duration of the key press exceeds the threshold time value, wherein the display is configured to display a graphical element, which indicates a duration of the key press at least until the threshold time value is reached.
