This document relates to an optical device that uses a mirror scanning system as part of a display engine, where images generated by the mirror scanning system can be propagated through a waveguide or other such optical assembly to a user's eye. The mirror scanning system can utilize a magnetic assembly, where the mirror of the scanning system can be held in place magnetically instead of using support structures such as torsion bars or beams. Actuators can then be actuated to control the tilt of the mirror by way of magnetic fields, providing a greater field of movement for the optical element and enabling a spherical scan area to be produced.

A head mounted display is provided. The head mounted display includes a first display module, a second display module, an adjustment mechanism, a first frame temple and a second frame temple. The adjustment mechanism is connected to the first display module and the second display module, wherein the adjustment mechanism is adapted to move the first display module and the second display module. The first frame temple is connected to the adjustment mechanism, wherein the first frame temple is adapted to move the adjustment mechanism. The second frame temple is connected to the adjustment mechanism, wherein the second frame temple is adapted to move the adjustment mechanism, the first frame temple and the second frame temple are adapted to rotate between a first posture and a second posture.

A head-up display system includes a hologram projector adapted to project a holographic image, a beam steering device adapted to adjust a look down angle of a holographic image projected through the beam steering device by the hologram projector, and a controller in communication with the hologram projector and adapted to compare the vertical location of the driver's eyes to a pre-determined nominal vertical position, and to adjust a virtual image distance of the holographic image projected by the hologram projector.

A head mounted display (HMD) includes an electronic display configured to display a virtual scene to a user, an optics block, an eye tracking system, and a varifocal actuation that mechanically changes a distance between the optics block and the electronic display. The varifocal actuation block is configured to change a location of an image plane of the HMD and includes a motor, a power screw coupled to the actuating motor configured to turn responsive to actuation of the motor, and a nut sled on the power screw that is coupled to the electronic display. The nut sled is configured to move back and forth along a length of the power screw responsive to the power screw being turned by the motor that results in movement of the electronic display relative to the optics block.

Disclosed is a sterile cover (100) for a Mixed Reality (MR) device (101). The sterile cover (100) may comprise a first case (102) arranged for covering a front side of the MR device (101). The first case (102) may comprise a hard case with an embedded clear layer (114) for covering a glass area of the front side of the MR device (101). The sterile cover (100) may further comprise a second case (104). The second case (104) may be arranged for covering a headband side of the MR device (101). The second case (104) may comprise a stretchable case for allowing a flexible adjustment of the headband side of the MR device (101) within the second case (104).

A head-mounted display including; a main body configured to generate a display image; a belt configured to fix the main body to a head of a user; a first sensor configured to detect a fastening strength of the belt; a storage unit configured to store a setting regarding the fastening strength of the belt; and a drive unit configured to fasten the belt in accordance with the detection result of the first sensor and the setting.

A head mounted display device and a positioning device thereof are provided. The positioning device includes a first sensor, a second sensor, a third sensor, a first hinge sensor, and a controller. The first sensor and the second sensor have a fixed relative location. The third sensor is disposed on a first flexible member of the head mounted display device. The first hinge sensor is disposed on a first connecting portion configured to connect a main body portion and the first flexible member, wherein the first hinge sensor is configured to sense a first movement state of the first flexible member. The controller is configured to calculate a first relative location information of the first sensor, the second sensor, and the third sensor, and to calibrate the first relative location information according to the first movement state.

The problem relates to an arrangement for a flexible flat component which comprises a front side and a rear side, wherein the arrangement comprises a flat stabilization element and lamellas, wherein the lamellas are arranged on the rear side of the component, wherein the component can be deformed, wherein the stabilization element is designed to cooperate with the lamellas on the rear side of the component and to fix the component in a shape that the respective component is respectively currently in.

A display system is provided. The display system includes a windshield, a picture generation unit (PGU), and an optical element, where the windshield includes a first windshield surface and a second windshield surface. The PGU projects a light beam corresponding to a picture generated by the PGU to the optical element. The optical element directs the light beam to the first windshield surface. The first windshield surface refracts the light beam to the second windshield surface, and reflects the light beam to a human eye for receiving. The first windshield surface refracts a light beam reflected from the second windshield surface to the human eye for receiving. After reflection by the first windshield surface, the light beam forms a first virtual image with the picture. After reflection by the second windshield surface and refraction by the first windshield surface, the light beam forms a second virtual image with the picture.

According to at least one aspect, the present disclosure provides a head-up display device comprising: a housing including a receiving space within; a picture generation unit (PGU) disposed within the housing, for projecting an image related to vehicle driving information; one or more reflection members for reflecting an image projected from the PGU; a fixing member formed to be fixed to a vehicle body; and one or more length adjustment members coupled to the fixing member, for movably supporting the housing.
