    Abstract: Techniques described herein are directed to adaptive virtual reality and augmented reality viewing based on a user's eye condition data. In a first implementation, a software application renders video content based on the user's eye condition data by mapping the user's eye condition data to video rendering parameters. The video content rendered based on the user's eye condition data may be made available to a virtual reality/augmented reality player and played using a head mounted display. The video content rendered based on the user's eye condition data may be pre-rendered before video content playback or rendered in real time during video content playback. In an additional implementation, the head mounted display may be calibrated and adjusted based on the eye condition data prior to video playback.

  • Patent number: 10330936
    Abstract: A head mounted display (HMD) adjusts the phase of light of a virtual scene using a spatially programmable focusing element. Depths of the virtual scene are approximated to one or more focal surfaces and the shape of the focal surfaces is then adjusted to minimize the distance of the focal surface to features in the virtual scene. The resulting shape of the focal surface is a continuous piecewise smooth three-dimensional curve. A phase function is generated for each focal surface that, when executed by the spatially programmable focusing element, reproduces a focal pattern corresponding to the each focal surface, which bends and shapes the wavefront to produce a focal pattern that conforms to the scene geometry.

  • Patent number: 9025088
    Abstract: The present invention relates to a sectional dynamic-driving backlight module and a head-up display device thereof. The sectional dynamic-driving backlight module comprises an optical-directional lens unit and an optical-homogenizing unit. The optical-directional lens unit is provided for converging the light beams emitted by the light source assemblies in the backlight module into light beams with a smaller divergent angle, and the optical-homogenizing unit is used for further homogenizing the light beams, so as to make all display regions of the LCD show a uniform illumination. Therefore, all images showed on an eyebox of the driver are distinct. Besides, each of the light source assemblies consist a red-light LED chip, a green-light LED chip, a blue-light LED chip, and a white-light LED chip, and these LED chips may be controlled by a controlling PCB for lighting respectively or simultaneously, so as to achieve a sectional dynamic display.

  • Patent number: 9025252
    Abstract: The technology provides for adjusting a see-through, near-eye, mixed reality display device for alignment with an inter-pupillary distance (IPD) of a user by different examples of display adjustment mechanisms. The see-through, near-eye, mixed reality system includes for each eye a display optical system having an optical axis. Each display optical system is positioned to be seen through by a respective eye, and is supported on a respective movable support structure. A display adjustment mechanism attached to the display device also connects with each movable support structure for moving the structure. A determination is automatically made as to whether the display device is aligned with an IPD of a user. If not aligned, one or more adjustment values for a position of at least one of the display optical systems is automatically determined. The display adjustment mechanism moves the at least one display optical system in accordance with the adjustment values.

    Abstract: Provided is a head-up display (HUD) device capable of effectively preventing damage to a liquid-crystal display device due to entry of exterior light. A HUD device has a liquid-crystal panel, and is provided with a liquid-crystal display device for realizing a transparent display using light from a backlight, a control means for controlling the liquid-crystal display device, and an optical system for reflecting the display light outputted by the liquid-crystal display device onto a windshield. A flat mirror constituting the optical system allows infrared rays of incident light to pass behind the mirror and reflects the visible light. The HUD device is provided with an infrared-ray sensor positioned behind the flat mirror, and the control means reduces the brightness of the light of the backlight or extinguishes the backlight when the strength detected by the infrared-ray sensor exceeds a predetermined threshold.

    Abstract: Provided is a display device for a vehicle that can, in a configuration in which the cost of parts is curbed, quickly raise the temperature of a laser light source (LD) in a low temperature environment, and quickly perform stable image output. The LDs (11, 12, 13) emit laser light (RGB) and an MEMS mirror (30) scans the laser light (RGB) and generates a display image (M). A convex mirror (70) reflects display light (L) indicating the display image (M) in an external direction via a translucent light-transmitting unit (90). An LD driving means (101) emits laser light (RGB) to the LDs (11, 12, 13) when the temperature is low, and causes the LDs (11, 12, 13) to perform self-heating driving for raising the temperature of themselves.
