A wearable display device that is a display device, an information processing device configured to connect to a wearable display device, a first sensor including a first geomagnetic sensor, a second sensor including a second geomagnetic sensor, and a display control part configured to change a display mode of the wearable display device in accordance with a relative positional relationship between the wearable display device and the information processing device on the basis of a detection result are provided.

Various implementations disclosed herein include devices, systems, and methods that enable improved display of virtual content in computer generated reality (CGR) environments. In some implementations, the CGR environment is provided at an electronic device based on a field of view (FOV) of the device and a position of virtual content within the FOV. A display characteristic of the virtual object is adjusted to minimize or negate any adverse effects of the virtual object or a portion of the virtual object falling outside of the FOV of the electronic device.

A display control apparatus includes: an input unit that receives state information indicating at least one of a state of a moving object, a state of inside of the moving object, and a state of outside of the moving object; and a controller that controls a displayer, which generates a predetermined image and outputs the predetermined image onto a display medium, based on the state information. The predetermined image shows a presentation image including text, when displayed on the display medium. The controller causes the displayer to generate a first predetermined image showing a first presentation image including first text corresponding to a predetermined event, determines whether the at least one state has made a predetermined change, based on the state information, and causes the displayer to generate a second predetermined image showing a second presentation image including second text corresponding to the predetermined event.

This dynamic image processing device (20) for a head mounted display includes an attitude detection means (30) capable of detecting the attitude of an imaging device affixed to the head of a user, a first image deviation amount calculation means (41) that calculates a first image deviation amount (G1) in the yawing and pitching directions of the imaging device based on the detection result of the attitude detection means, a second image deviation amount calculation means (42) that calculates a second image deviation amount (G2) between a past image (52) and a current frame image (51) based on the first image deviation amount, the current frame image captured by the imaging device, and the past image, and an image synthesis means (43) that corrects the past image based on the second image deviation amount and synthesizes the past image and the current frame image.

A projector for HUD includes a displaying component (1) configured to project an image, and a three-mirror optical device (10) configured to reflect the image onto a front windshield (5) which reflects the image to a driver's eyes. The three-mirror optical device (10) comprises a zoom lens assembly (2) having a zoom lens (21) for zooming in/out the image projected by the displaying component (1), and an image quality compensation lens assembly (3) having an image quality compensation lens (31) for compensating for an image quality distortion caused during a change of the focus of the zoom lens(21), and a front windshield compensation lens assembly (4), configured to compensate for a distortion caused by the front windshield (5). A first and a second focus adjusting component (22, 32) are configured to adjust the focus of the zoom lens (21) and the focus of quality compensation lens (31), respectively.

A virtual reality system and a method of controlling working state of the virtual reality system. The virtual reality system comprises a video playing device and a virtual reality glasses box, and the virtual reality glasses box utilizes a screen of the video playing device to play a video content, the method comprises: establishing a wired or wireless connection between the video playing device and the virtual reality glasses box; when the video playing device is placed in the virtual reality glasses box, transmitting information of wearing state of the virtual reality glasses box to the video playing device; and controlling a playing state of the video playing device according to the wearing state of the virtual reality glasses box. The present disclosure controls the working state of the virtual reality device by the action of the user operating the device itself, and the user does not need to employ tedious and complicated operations to control each of the devices, which increases usability, and improves user experience.

A battery system for a head-mounted display is provided. A first arm member has one or more interior walls defining a first chamber, wherein one or more first batteries are positioned in the first chamber of the first arm member. A second arm member has one or more interior walls defining a second chamber, wherein one or more second batteries are positioned in the second chamber of the second arm member. A base member is coupled to the first arm member and the second arm member. The base member has a base member power connector positioned along an exterior surface. A first auxiliary battery removably couples to the exterior surface of the base member via a first fastener, the first auxiliary battery having a first side and a second side. A first auxiliary battery power connector is positioned on the first side and aligns with the base member power connector.

Systems and methods for auto-calibrating a virtual reality (VR) or augmented reality (AR) head-mounted display to a given user with a refractive condition without adding corrective lenses to optical elements of the head-mounted display and without requiring subjective refraction procedures. A method comprises projecting a grid onto an eye of a user using a light source of a head-mounted display worn by the user, capturing the grid as-reflected from the eye using a camera of the head-mounted display, determining a pattern of a reflection of the grid based on the grid as-reflected, generating an aberration map based on a difference between the pattern as-reflected and the grid as-projected, and determining a correction to apply to at least one viewing lens of the head-mounted display worn by the user based on the aberration map.

A head up display arrangement for a motor vehicle includes a picture generation unit producing a light field. An optical element reflects the light field such that the light field is visible to a human driver of the motor vehicle as a virtual image. A holographic film is attached to the optical element. A driver monitoring system senses infrared energy reflected by the holographic film.
