A heads-up display may comprise a viewing screen having a reflective surface; a housing defining an opening; a display element disposed within the housing and comprising an integral linear polarizer configured to polarize light in a first direction; and a first linear polarizer disposed between the display element and the viewing screen covering the opening defined by the housing configured to polarize light in the first direction. The display element may be capable of causing images to be displayed on the viewing screen.

Provided are a content visualizing device and method that changes positions and shapes of route guidance content and driving related content based on a distance to an adjacent object, a current driving state, and an occurrence of a driving related event.

A method which makes it possible to immerse a user in a virtual reality application is described. The method includes controlling the movement of an avatar of a user in a synthetic scene and controlling the movements of a video acquisition system depending on the detected movements of the head of the user. The method also includes playing back content on a screen of a virtual reality helmet of the user, the content being a video stream acquired by the video acquisition system if the position of the eyes of the avatar is in a synthetic object whose volume can be included in a volume in which the video acquisition system is likely to move.

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

There is provided a display device for a vehicle, the display device including: a display unit that is visible to an occupant of a vehicle; a memory; and a processor that is connected to the memory, the processor changing a content image displayed on the display unit so as to be displayed in the same direction as a direction in which a travel path of the vehicle curves.

The present disclosure provides a virtual reality system. The virtual reality system of the disclosure, comprising: a head-mounted display, an input device and a positioning module, wherein the head-mounted display comprises a central processing unit, a camera module connected with the central processing unit and a wireless connection module; the camera module comprises a binocular fisheye camera, an IR camera and a TOF camera, the positioning module comprises a first inertial measurement unit and an electromagnetic receiver provided on the head-mounted display, a second inertial measurement unit and an electromagnetic transmitter provided on the input device; the central processing unit, configured to implement data interaction and command control with the binocular fisheye camera, the IR camera, the TOF camera, the wireless connection module, the first inertial measurement unit and the electromagnetic receiver.

The disclosed subject matter relates to a method of manufacturing a light projector module, comprising the steps of: providing a base plate, a light source on the base plate, and a micro-electro-mechanical-system (MEMS) scanning assembly, wherein the base plate has, between the light source and the MEMS scanning assembly, a mounting surface accessible at one side of the base plate; positioning a set of one or more lenses on the mounting surface and adjusting the position of the one or more lenses of the set while the light source is emitting and at least one light beam projected by the light projector module is monitored in a display area; and mounting the one or more lenses of the set in the adjusted position fixedly on the base plate.

A head-up display includes a display panel, a reflective optical element, a controller, and an obtainer. The display panel displays a first image. The reflective optical element reflects image light from the first image displayed by the display panel. The controller controls a position at which the first image is displayed on the display panel. The obtainer obtains, as positional information, a position of an eye of a user. The controller changes the position at which the first image is displayed on the display panel in accordance with the positional information.

An object is to provide a head-mounted display apparatus that makes it possible to accurately determine a mounting deviation. The technology provides a head-mounted display apparatus including a sensor that detects a change in position of the head-mounted display apparatus relative to a head. The technology further provides an image display system including the head-mounted display apparatus and an information processor that sends image data to the head-mounted display apparatus. The technology further provides an image display method including a detection step of detecting the change in position of the head-mounted display apparatus relative to the head, and an adjustment step of adjusting a position to which the head-mounted display apparatus projects image display light on the basis of the change in position detected in the detection step.
