A display control device controls a superimposed display of a content by a head-up display for a vehicle. The display control device estimates a visible area of a road surface in a foreground included in an angle of view of the head-up display, and an invisible area of the road surface in the foreground included in the angle of view; distinguishes, in a route content, a visible part superimposed in the visible area, an invisible part superimposed in the invisible area, and an overlapping portion between the visible part and the invisible part; and causes the overlapping portion to be displayed in a display mode different from display modes of a visible non-overlapping portion of the visible part out of the overlapping portion and an invisible non-overlapping portion of the invisible part out of the overlapping portion.

Systems, methods, and computer program product for displaying virtual content with a wearable display device that in response to identifying a first change from a first field of view to a second field of view, determines, based at least in part upon attribute(s) or criterion (criteria), first virtual content element(s) and second virtual content element(s) from the set that match to first surface(s) within the first field of view, determines second surface(s) within the second field of view based at least in part upon attribute(s) or criterion (criteria), the second surface(s) matching to the second virtual content element(s), moves the first virtual content element(s) from the first surface(s) to the second surface(s), and maintains the second virtual content element(s) with respect to the first surface(s) while the first field of view has been changed into the second field of view.

Devices, methods and computer program products that facilitate automated adjustment of size or configuration of head up display image in a vehicle. A device can include a memory and a processor that executes computer executable modules. The computer executable modules can include: a head up display that generates an image visible to a driver of a vehicle within an eye box, a detection module that determines position of the driver's eyes or head relative to position of the eye box, and an adjustment module that adjusts size or configuration of the image within the eye box in response to the determined driver's eye or head position.

A port assembly for controlling fluid flow through a flow port of a port sub. The port assembly comprises a dissolvable barrier, a burst disk for protecting the dissolvable barrier from fluids inside the port sub, and optionally a protective layer for protecting the dissolvable barrier from external fluids. When the burst disk is ruptured by increased fluid pressure inside the port sub, the dissolvable barrier starts disintegrating from exposure to the fluid. When the dissolvable barrier and protective layer are broken through, a flow passage is opened in the port assembly to permit fluid flow therethrough. The flow passage may be positioned tangentially in the port sub. The breakthrough time of the dissolvable barrier may be preconfigured by providing one or more thinner areas therein and/or placing a corrosive material in the port assembly.

A display method of an electronic device includes following steps. Providing a first image by a display, and a first vergence plane of two eyes of a user is located at a first position when the user views the first image. Providing a second image by the display, and the first image, the second image and an environmental scene are located within a field of view of the user, and a second vergence plane of the two eyes of the user is located at a second position when the user views the second image. A first distance exists between the first position of the first vergence plane and the user, a second distance exists between the second position of the second vergence plane and the user, and the first distance is different from the second distance.

A method for applying adapted colour rendering in relation to intensity of light of wavelengths relevant to the circadian rhythm of a user, a computer program, a carrier, a system and a head-mounted device is disclosed. The method comprises receiving gaze tracking information identifying a gaze vector of the user of the system, and determining a respective location of a first area of the display and a second areas of the display based on the identified gaze vector. A first colour rendering mode is applied in the first area of the display, and a second colour rendering mode is applied in the second area of the display. The first colour rendering mode and the second colour rendering mode differ in relation to a degree of selective adaptation of intensity of light of wavelengths relevant to the circadian rhythm of the user.

The disclosure is directed to a novel responsive layout that allows the user to build one layout that can fit on all or virtually all device form factors according to some embodiments. In some embodiments, the responsive layout is configured to allow users to arrange their content based on the size and shape of a display. In some embodiments, the system is configured to receive a request to access content through a computer and in response to the request, automatically generate a responsive layout based on a display size and a content of the request. In some embodiments, the responsive layout includes a responsive layout editor pane configured to allow the user to customize the responsive layout as desired.

Systems and method herein describe an electronic display apparatus that is amendable to display different types of visualizations. In an embodiment, the electronic display apparatus has a circular display unit. The electronic display apparatus may display content but with some of the portions cut off from visibility to a user. The electronic display apparatus may include motion sensor units and data obtained from these motion sensor units may be used to cause a video controller to send a portion of the content from a frame buffer to the display device to enable the display of different areas of content. The content displayed to the user may change in accordance with movement initiated by the user.

This application discloses a display method and a display control apparatus. The display system includes a projection screen, the projection screen includes a transparent substrate and a liquid crystal film covering the transparent substrate, and the liquid crystal film includes a plurality of liquid crystal cells. The display method includes: obtaining a to-be-displayed image; determining a target liquid crystal cell from the plurality of liquid crystal cells based on locations of pixels in the to-be-displayed image; setting a status of the target liquid crystal cell to a scattering state, and setting a status of a non-target liquid crystal cell to a transparent state, where the non-target liquid crystal cell is a liquid crystal cell in the plurality of liquid crystal cells other than the target liquid crystal cell; and displaying a projection image of the to-be-displayed image on the target liquid crystal cell.

An electronic apparatus is provided. The electronic apparatus includes at least one housing which may have a plurality of states, at least one display, and at least one processor. The at least one processor is set to display a first execution screen of at least one application on a first display area of the at least one display when the at least one housing is in a first state, wherein the first display area corresponds to the first state, identify the transition of the at least one housing from the first state to a second state, display a first screen, which includes at least one graphic object, on the second display area when a first condition is satisfied, wherein the first screen is displayed on the basis of the transition of the at least one housing from the first state to the second state, and display a second execution screen of a first application on at least a portion of the second display region in response to a first input to a first graphic object, corresponding to the first application, among the one or more graphic objects.
