Embodiments of the present disclosure describe an electronic device for providing a visual effect corresponding to a gesture input. The electronic device includes a sensor, a wireless communication circuit, a display device, and at least one processor. The at least one processor is configured to sense a gesture input through the sensor. The at least one processor is also configured to control the display device to display a first visual effect corresponding to the gesture input. When information related to the first visual effect is received from another electronic device through the wireless communication circuit, the at least one processor is configured to update the first visual effect displayed on the display device to a second visual effect.

A method of presenting visual information to a user includes detecting a position of a display relative to a surrounding environment, detecting movement of the display relative to the surrounding environment in real time, and updating a present of visual information on the display relative to a virtual reference frame updated in real time based upon the movement of the display relative to the surrounding environment.

A computing device may include a processor and memory configured to determine a factor in which to scale content displayable on a client computing device based upon a ratio of physical sizes of different screens on which to display the content. One of the different screens may be that of the client computing device. The processor may be configured to select a portion of the content to display on the client computing device based on the determined factor and a position within the content at which there is an indication of interest. The processor may be further configured to transmit the selected portion of the content to the client computing device, so as to enable display of the selected portion rather than an entirety of the content.

The present disclosure provides technologies that enable users to graphically merge content displayed on a first computing device with content displayed on a second computing device by the use of a simplified gesture. For example, a user can hold a portable computer displaying content up to a screen of another computer displaying other content. The user can position the portable computer to align the rendering of the content with a rendering of the other content. Measurements of the alignment are processed to determine a location that is used to graphically merge the content of the portable computer at a specific location within the other content. A scaling factor can be used to control the size of the content that is placed within the other content. The scaling factor can be based on a user gesture, preference data, or knowledge of a computing device.

A display control method includes outputting, by at least one video output device, M videos, M being an integer larger than or equal to 1, if M<N, displaying the M videos in each of M sub-areas by respectively assigning each of the M videos to each of the M sub-areas obtained by dividing a single large area in which an image is displayed by N display devices, N being an integer larger than or equal to 2, and if M=N, displaying each of the M videos by assigning each of the M videos to each of N display areas corresponding to the N display devices respectively.

A display panel control chip including a processor and a signal processing circuit is provided. The processor controls a display panel to display first and second images corresponding to first and second video signals. The first image is adjacent to the second image by a border extending in perpendicular to a first direction at a first coordinate. The signal processing circuit stores the first coordinate, determines whether a first cursor is in the first image or the second image according to a cursor control signal and the first coordinate, and transmits, according to the determination, the cursor control signal to either a signal source of the first video signal or a signal source of the second video signal. When an area ratio of the first image to the second image is changed, the processor controls the signal processing circuit to update the first coordinate.

An application engine renders an image based on image data from a content source. A display engine displays the image to a user. The image is adjustable from a first size to a second size. A detection system detects the size adjustment. An application executes a clarification routine to maintain sharpness of the image.
