An HMD device is configured to vertically adjust the ground plane of a rendered virtual reality environment that has varying elevations to match the flat real world floor so that the device user can move around to navigate and explore the environment and always be properly located on the virtual ground and not be above it or underneath it. Rather than continuously adjust the virtual reality ground plane, which can introduce cognitive dissonance discomfort to the user, when the user is not engaged in some form of locomotion (e.g., walking), the HMD device establishes a threshold radius around the user within which virtual ground plane adjustment is not performed. The user can make movements within the threshold radius without the HMD device shifting the virtual terrain. When the user moves past the threshold radius, the device will perform an adjustment as needed to match the ground plane of the virtual reality environment to the real world floor.

A wearable heads-up display includes a power source, laser sources, and a lightguide. A photodetector is positioned to detect an intensity of a test light emitted at a perimeter of the lightguide from an optical path within the lightguide. A laser safety circuit provides a control to reduce or shut off a supply of electrical power from the power source to the laser sources in response to an output signal from the photodetector indicating that the detected intensity is below a threshold.

An opto-electronic device (100) is disclosed. The opto-electronic device (100) comprises at least one sensor (106) configured to obtain head orientation data including information on an orientation of a user's head, a processing unit (112) configured to process the head orientation data so as to obtain self motion data including information on the user's self motion and to provide at least one visual cue (114) based on the obtained self motion data, and a display device (120) configured to display the at least one visual cue (114) at a dis-play (102) at least in a periphery of a visual field of the user. Further, a method for providing visual orientation is disclosed.

The invention relates to electronic engineering, more specifically to displays on a car windshield, even more specifically to projection IA qui d crystal displays with biologically adequate backlighting based on semiconductor light-emitting diodes (LEDs) for displaying augmented reality images on a car windshield. The display on the windshield of a car includes LED backlighting arranged in series along the optical axis, Consisting of at least one LED with a peak blue radiation wavelength of 475-490 nm, an optical film system including diffusely scattering and raster prismatic films designed to ensure uniformity illumination radiation, and a composite (zoned) composite photoluminescent film containing photoluminescent substances in a transparent base for converting blue LED radiation into green-blue radiation for the augmented reality display area and red radiation for the warning information display area, monochrome liquid crystal display, a Fresnel lens that magnifies the image formed on the liquid crystal display into the space in front of the windshield of the vehicle. The technical result consists in reducing the harmful effects of display radiation on the body of the driver and passengers of the car, simplifying the design, increasing the reliability and efficiency of the display on the windshield of the car.

Systems, methods, and non-transitory computer readable media containing instructions for causing at least one processor to perform operations for determining a display configuration for presenting virtual content are provided. In one implementation, the processor is configured for receiving image data from an image sensor associated with a wearable extended reality appliance; analyzing the image data to detect a particular input device placed on a surface; determining a value of at least one use parameter for the particular input device; retrieving from memory default display settings associated with the particular input device; determining a display configuration for presenting virtual content based on the value of the at least one use parameter and the retrieved default display settings; and causing a presentation of the virtual content via the wearable extended reality appliance according to the determined display configuration.

An example display system for a commercial vehicle includes a camera configured to record images of a blind spot of the commercial vehicle and a wearable augmented reality display device that includes an electronic display and is configured to be worn on the head of a driver of the commercial vehicle. An electronic control unit is configured to display graphical elements on the electronic display that depict at least one of portions of the recorded images and information derived from the recorded images. A method of displaying graphical elements is also disclosed.

A wearable head-up display which allows for convenient and safe stowage when not in use. A hinge component is positioned within the optical path from an image projector to a display component which ensures optical alignment for projection. A detection means is provided to signal when the wearable device is in a folded position in order to deactivate the projector.

Systems and methods for augmented-reality-based marine navigation. An electronic controller plots a navigational route between a current geospatial position of a host vessel and a target destination of the host vessel. The navigational route is plotted as a series of waypoints. The electronic controller receives an electronic transmission from at least one nearby ship indicative of a current position of the at least one nearby ship (e.g, an MS transmission) and updates the navigational route based at least in part on the received electronic transmission. A graphical representation of the updated navigational route and a graphical indication of the current position of the at least one nearby ship (e.g., a conformal overlay of the at least one nearby ship) are then displayed on a head-worn augmented reality display device.

An integrated computational interface device includes a housing, at least one image sensor, and a foldable protective cover. The housing has a key region and a non-key region, and a keyboard associated with the key region. The foldable protective cover incorporates the at least one image sensor. The protective cover is configured to be manipulated into a plurality of folding configurations, including a first folding configuration, wherein the protective cover is configured to encase the key region and at least a portion of the non-key region, and a second folding configuration, wherein the protective cover is configured to stand in a manner that causes an optical axis of the at least one image sensor to generally face a user of the integrated computational interface device while the user types on the keyboard.

Is addressed. A video transmissive head-mounted display device capable of avoiding danger to a user when worn by the user has an external world image acquired by a first image inputting unit, and the external world image is displayed on a display unit. The head-mounted display device has a second image inputting unit that acquires a binocular image of a wearer. The head-mounted display device is configured so that a control unit determines, from the binocular image of the wearer acquired by the second image inputting unit, that the wearer is awake when both eyes are closed for no longer than a predetermined period of time and that the wearer is asleep when both eyes are closed for a predetermined period of time or longer, and the display unit displays the external world image acquired by the first image inputting unit when the wearer wakes from sleep.
