A communication head-up display system includes a communication device and a head-up display. The communication device includes a first controller which determines eye-positions of eyes of a user in at least one direction. The head-up display includes a display panel, an optical element, a reflector. The display panel displays a parallax image. The optical element defines a propagation direction of image light emitted from the parallax image. The reflector reflects the image light whose propagation direction is defined by the optical element. The reflector includes a reflection element and a drive device. The reflection element reflects the image light. The drive device changes at least one of position and posture of the reflection element so that the image light reflected by the reflection element arrives at the eye-positions.

A virtual image display system includes an image data producing unit, an image display, and an optical system. The image data producing unit produces, based on image data of a rendering target and position information about a display position of the target, image data to display a virtual image of the target. The image display displays, on a display screen, an image based on the image data to display the virtual image. The display screen is arranged to be tilted with respect to an optical path leading from the display screen to the optical system. The image data of the rendering target includes first image data of a stereoscopic rendering target. The image data producing unit produces, based on the first image data and position information about a display position of the stereoscopic rendering target, second image data to make the user view the stereoscopic rendering target stereoscopically.

An assembly includes a movable laser projector configured to project images and to also act as a mapping apparatus such as a LIDAR apparatus configured to generate a data structure representing a three-dimensional map of a space. A head mount (HM) includes a camera to generate signals representing the gaze direction of the wearer of the HM. The laser projector moves according to the signals to project images in the space using the data structure generated by the mapping apparatus.

A mixed reality system that includes a head-mounted display (HMD) that provides 3D virtual views of a user's environment augmented with virtual content. The HMD may include sensors that collect information about the user's environment (e.g., video, depth information, lighting information, etc.), and sensors that collect information about the user (e.g., the user's expressions, eye movement, hand gestures, etc.). The sensors provide the information as inputs to a controller that renders frames including virtual content based at least in part on the inputs from the sensors. The HMD may display the frames generated by the controller to provide a 3D virtual view including the virtual content and a view of the user's environment for viewing by the user.

A head-up display includes a display device and an optical system. The display device includes a display panel, an input unit, a memory, and a controller. The display panel is configured to display an image. The input unit is configured to receive calibration information indicating a position of a calibration object and first position information indicating positions of user's eyes based on an image capturing device. The memory is configured to store the calibration information. The optical system is configured to allow a user to visually recognize a virtual image plane, which is a virtual image of the image displayed on the display panel, by reflecting image light emitted corresponding to the image toward the user's eyes. The controller is configured to convert the first position information into second position information indicating the positions of the eyes based on the virtual image plane by using the calibration information.

Architecture and designs of wearable devices for viewing multimedia in 3D are described. According to one aspect of the present invention, a display device is made in form of a pair of glasses. A separate enclosure is provided to generate content for display on the glasses. The content is optically picked up by an optical cable and transported by one or more optical fibers in the optical cable to the glasses, where an image polarizer, deposed on or included in the bridge of the glasses, receives the content and produces an alternating polarized content sequence.

An example of an image display system includes a goggle apparatus including a display section. A virtual camera and a user interface are placed in a virtual space. In accordance with the orientation of the goggle apparatus, the orientation of the virtual camera in the virtual space is controlled. For example, in a case where the line of sight of the virtual camera rotates in a left direction in a yaw direction and then reverses in a right direction, and when the amount of change in the right direction is greater than or equal to a threshold, the user interface is moved to the front of the virtual camera.

An image projection system includes: eyeglasses including a frame, a first eyeglass lens, and a second eyeglass lens; and a binocular light engine coupled to the frame. The binocular light engine includes a first light transmitter configured to transmit a first plurality of light beams corresponding to a first stereoscopic image on a first transmission path; a second light transmitter configured to transmit a second plurality of light beams corresponding to a second stereoscopic image on a second transmission path; and a single scanning structure shared by the first transmission path and the second transmission path. The single scanning structure is configured to: rotate about two scanning axes, direct the first plurality of light beams at the first eyeglass lens according to a scanning pattern, and direct the second plurality of light beams at the second eyeglass lens according to the scanning pattern.
