An electronic device is provided. The electronic device includes a communication circuit, and at least one processor operatively connected to the communication circuit, wherein the at least one processor is configured to establish, via the communication circuit, a communication connection with a display device, identify channel information about a first channel on which the communication connection is established, identify image information about an image displayed in the display device, and based on the channel information about the first channel and the image information, identify whether the electronic device is capable of transmitting a data frame each communication cycle which corresponds to a frame rate provided in the display device.

An electronic device, an electronic system, and a control method are provided. The electronic device includes a display, a memory, and a processor. The memory stores an audiovisual module and a control module. The processor receives initial image information from an external electronic device through a bridge device. The processor is coupled to the display and the memory. The processor executes the audiovisual module to transform the initial image information with a first image format into transformed image information with a second image format, which is compatible to the display. The processor controls the display to display according to the transformed image information. The processor executes the control module to receive a control signal for operating the transformed image information, and provide the control signal to the external electronic device through the bridge device.

Systems and methods for reducing latency on a collaborative platform are provided. The collaborative platform involves a display, a moderator device, one or more member devices, and a receiver in communication with the display, the moderator device, and the one or more member devices. To reduce latency of the collaborative platform, the receiver generates an overlay image based on user input received from the display, as well as user type of the user input, generates an overlaid image based on the overlay image, and transmits the overlaid image for display, while a collaboration application generates new real image(s) based on the user input for display. The overlaid image generated may be indicative of actual user input as well as predicted user input using extrapolation and/or machine learning.

An electronic device is provided. The electronic device includes wireless communication with an external device, that determines a reference display position at which an extended screen of a mobile device is to be provided based on a wireless communication signal of the external device, and when a portion of the extended screen is included in a field of view (FOV), provides a user with the extended screen starting with the portion coming into the FOV.

A first electronic device with a touch-enabled display establishes a wireless connection with a second electronic device that controls display of a user interface on a second display. The first electronic device displays a first user interface on the touch-enabled display, the first user interface including a first affordance corresponding to first media content. While displaying the first user interface, the first electronic device detects a first user input at a location on the touch-sensitive display that corresponds to the first affordance in the first user interface. In response to detecting the first user input, the first electronic device transmits, to the second electronic device via the wireless connection, instructions enabling display of at least a portion of the first media content on substantially the entire second display controlled by the second electronic device.

An apparatus, method, and computer readable medium that access a frame buffer of a graphics processing unit (GPU), analyze, in the frame buffer, a frame representing displayed data, based on the analyzed frame, identify a reference patch that includes an instruction to retrieve content, generate an overlay including an augmentation layer which includes the content, superimpose the overlay onto the displayed data such that the content is viewable while a portion of the base layer is obscured, detect a user input, determine a location of the user input in the augmentation layer, associate the location in the augmentation layer with a target location in the base layer, and associate, within memory, the target location with an operation such that the user input in the augmentation layer activates an input in the base layer.

The collaborative platform involves a display, a moderator device, one or more member devices, and a receiver in communication with the display, the moderator device, and the one or more member devices. To reduce latency of the collaborative platform, the receiver generates an overlay image based on user input received from the display, as well as user type of the user input, generates an overlaid image based on the overlay image, and transmits the overlaid image for display, while a collaboration application generates new real image(s) based on the user input for display. The overlaid image generated may be indicative of actual user input as well as predicted user input using extrapolation and/or machine learning.

A file processing method, an electronic device, a system, and a storage medium are provided. The method includes: A second electronic device projects onto a first electronic device, and generates a collaboration window on the first electronic device; it is detected that a target file in the first electronic device is dragged by a first operation to an icon of a first application in the collaboration window, and the first operation is released, and the first application is used to open the target file in the collaboration window; and it is detected that the target file in the first electronic device is dragged by a second operation to an icon of a second application in the collaboration window, and the second operation is released, and the second application is used to open the target file in the collaboration window.

The disclosure provides a display apparatus and a cast method, including: a display; a rotation assembly; and a controller configured to receive image information sent from a terminal device. When the terminal is in a portrait mode, the image information includes effective area information and left and right black area information. The effective area information corresponds to content displayed on a current screen of the terminal device. The display is controlled to present a cast image based on the effective area information. The cast image is obtained by enlarging the effective area information by preset times.

A display apparatus includes two cameras and detects a second point and a third point with respect to a first point from photographed video, the first point indicating a camera reference position, the second point indicating a user reference position, the third point indicating a position of a finger of the user; sets a virtual plane space to a fourth point in a space, the fourth point being positioned apart from the second point by a predetermined length in a first direction; determines a predetermined operation on a basis of a degree of entrance of the finger with respect to the virtual plane space; controls an operation of the display apparatus on a basis of operational input information; determines an adjusting operation against the virtual plane space by the user; and changes at least one of a position, a size, or inclination of the virtual plane space in real time.
