The present disclosure provides an augmented reality display device. The augmented reality display device includes an adjustable light transmissive sheet, a spatial three-dimensional reconstruction component, and a control unit. The adjustable light transmissive sheet includes a plurality of pixels, the light transmission of each of the plurality of pixels being controllable. The spatial three-dimensional reconstruction component can obtain the depth value of each real point of the real scene in the user's field of view. The control unit can compare the depth value of the virtual point displayed in the same pixel with that of the real point. When the depth value of the real point is greater than that of the virtual point, the pixel is controlled to be opaque; and when the depth value of the real point is smaller than that of the virtual point, the pixel is controlled to be transparent.

A holographic system comprises a display device and a waveguide pupil expander. The display device is arranged to display a hologram and to output spatially modulated light in accordance with the hologram. The waveguide pupil expander is configured to receive spatially modulated light from the display device at the input port thereof and to expand the viewing window of the system. The waveguide pupil expander comprises first and second substantially planar reflective surfaces arranged in parallel having an optically transparent material therebetween. The first reflective surface is fully reflective and the second reflective surface is partially reflective such that light is guided from the input port to an output port at the second reflective surface by a series of internal reflections. The optically transparent material is formed by a layered glass structure arranged to maintain the integrity of the waveguide in the event of breakage of glass.

The present invention relates to an apparatus for displaying display information according to a driving environment and a method thereof. The apparatus for displaying display information according to the driving environment according to the present invention includes an input unit receiving driving environment information, a memory in which a program for controlling internal and external displays of a vehicle according to a driving environment is stored, and a processor executing the program, wherein the processor controls to select and project display information according to the driving environment information in an internal screen area and an external screen area according to preset partitioning.

Systems, devices, and methods for providing optical engines and laser projectors that are well-suited for use in wearable heads-up displays (WHUDs) are described. The optical engines of the present disclosure may integrate a plurality of laser diodes (e.g., 3 laser diodes, 4 laser diodes) within a single, hermetically or partially hermetically sealed, encapsulated package. Wavelength stabilization for the laser diodes is achieved by controlling the temperature of the lasers to always be in a particular range of operating specifications which provides wavelength stabilization that meets particular performance criteria. The lasers themselves may be used for temperature control by selectively switching them on to maintain their temperature within a specified range. Alternatively, compact resistive heaters may be positioned proximate the laser diodes to control the temperature of the laser diodes during operation. WHUDs that employ such optical engines and laser projectors are also described. Additionally, optical systems for collimating and shifting light beams are described.

Sensory feedback (chaperoning) systems and methods for guiding users in virtual/augmented reality environments such as walk-around virtual reality environments are described. Exemplary implementations assist with preventing collisions with objects in the physical operating space in which the user acts, among other potential functions and/or uses.

A display control device configured to control a projection device that projects an image on a windshield of a vehicle includes a circuitry. The circuitry is configured to determine a target ground object that is a ground object other than an object which a driver of the vehicle is to be warned of, the target ground object being used to provide the driver with a sense of distance to the object, and project, using the projection device, an image for indicating a presence of the object in a manner that allows the driver to perceive a sense of distance to the object on a windshield of the vehicle, such that a first part of the image and the target ground object overlap each other and a second part of the image and the target ground object do not overlap each other when viewed from the driver.

A safety system having at least one safety module, which is associated with a system controlled by a controller. A portable augmented reality unit is provided. The augmented reality unit has a camera and a projection unit. The safety module has a connection module. The connection module is designed to provide a data connection with the augmented reality unit, and further, a data connection with the controller. By means of the augmented reality unit, a code identifying the system is captured and transmitted to the connection module.
