A method for sharing content performed by at least one processor of a first user terminal includes initiating, through a first external device, a call between a first user account associated with the first user terminal and a second user account associated with a second user terminal included in a chat room of an instant messaging application, transmitting a co-view request associated with a content to share to the first external device, where the content to share is one of a plurality of contents shared within the chat room, and displaying the content to share with a call screen on a display of the first user terminal.

In a head mounted display 100, a memory 71 stores an application. An image pickup unit 74 takes an image of a site of a user 1, and a position specifying unit 73 specifies a position and a direction of the head mounted display 100. A detector 75 detects a position indicated by the user 1 on the basis of the image taken by the image pickup unit 74, and a setting unit 76 sets a position indicating a home position on the basis of a result detected by the detector 75 and the position and the direction specified by the position specifying unit 73.

A display apparatus including a housing; a display; a roller accommodated in the housing to rotate and roll or unroll the display; and a processor configured to in response to receiving a command to display content, control the roller to rotate and unroll the display from the housing so the display is drawn out and extended from the housing, and control the display to display an entire image of the content while simultaneously expanding a size of the entire image of the content as the display is being extended from the housing so a partial portion of the content is not blocked from being viewed as the display is drawn out and extended from the housing.

A video display device comprising; a display; an exercise amount detection sensor configured to detect an exercise amount of a viewer while the viewer is viewing content displayed and output sensor information; a timer that measures a viewing time; and a processor. The processor: acquires the viewing time from the timer; calculates the exercise amount of the viewer based on the sensor information acquired within a predetermined period of viewing time; compares the exercise amount with an exercise facilitation threshold for determining whether to facilitate exercise for the viewer; displays a specific object within a display area of the display when the exercise amount falls below the exercise facilitation threshold; and moves the specific object from an inside of the display area to an outside thereof in accordance with an external coordinate system expressing a position in a real space associated with a two-dimensional coordinate system in the display area.

Adaptive recoloring of displayed digital content automatically pursues specified active color palette goals while adhering to specified active color palette constraints. Source code editors, word processors, and other programs are enhanced by adaptive recoloring. Recoloring rules may specify coloring roles, colors, tolerances, color spaces, metrics, and other criteria. Recoloring may be triggered by a zoom or another change in user focus, by a brightness change, a screen size change, by notice of a user perception change, or by another event. Recoloring improves text legibility, assists user focus, compensates for differences in color perception and emotional impact, and increases color availability without degrading usability, for example. Transitions between words or other display items can be heightened. Branding colors may be preserved, in logos and text. Automatic selections may be overridden by a user command or by interactive tuning, with warnings given as appropriate.

A display control device is mounted on a vehicle and is configured to control display of information on a display device. The display control device includes an electronic control unit that determines whether there is information to be displayed on the display device, determines whether a predetermined first condition to determine that a driving operation by a user is not required is satisfied, determines whether a predetermined second condition to determine that the driving operation by the user is required is satisfied, controls the display device such that the display device displays the information when it is determined that there is information to be displayed on the display device and that the first condition is satisfied, and controls the display device such that the display device hides the information when it is determined that the second condition is satisfied.

A remote display device includes processing circuitry. The processing circuitry display a display screen. The processing circuitry generate a plurality of display data corresponding to mutually different display areas, each being a part of the display screen. The processing circuitry transmit the plurality of display data generated to a plurality of terminal devices, respectively. The processing circuitry update the display screen based on operation data indicative of an operation performed by the terminal device to the display area corresponding to the display data.

An apparatus for enlarging and displaying the screen and relaying the enlarged screen in real time include a reception unit that receives the entire screen of a provider from a relay server, a display unit that displays the received entire screen, a recognition unit that detects a user input on the displayed entire screen, and a controller that detects a change in input state of the user input and zooms in on a region corresponding to the user input, on the entire screen based on the change in input state. According to an embodiment, the apparatus has an effect capable of simultaneously receiving screen enlargement and a real-time relay service at the same time by means of only a simple operation using the portable electronic device. Furthermore, the apparatus has an effect capable of simply providing a screen enlargement real-time relay service for blind people with low vision.

An electronic device is provided. The electronic device includes a display including a plurality of display pixels, a memory, and at least one processor, wherein the at least one processor may be configured to drive the display by variably adjusting a first display region and a second display region in which visual information is to be displayed on the display, based on an operation state or a display structure state of the electronic device, calculate a difference in usage of the display between the first display region and the second display region, variably determine a size of a boundary compensation region between the first display region and the second display region, based on the difference in usage, and compensate for an image of the boundary compensation region.

Videos are to be displayed in parallel, without missing information or a decrease in efficiency in the usable display region.

The aspect ratio of the large screen of an information processing apparatus 100 is 16:9, which is compatible with a Hi-Vision video. In a case where the large screen is used in a portrait layout, if the large screen is divided into three small screens in the vertical direction, the aspect ratio of the small screens after the dividing is 9:16/3=16:9.48. With respect to the original video content at 16:9, the ratio in inches is 9/16=56.25% (the area ratio is (9/16).sup.2=31.64%). Accordingly, the usable display region can be efficiently used.
