A device and system for augmenting the focal length of an electronic display. The device may comprise a display, a first mirror, a second mirror, and a lens. The display is operable to emit light corresponding to a first image in a first direction. The first mirror has a first focal length and is operable to reflect light from the first direction to a second direction. The second mirror has a second focal length and is operable to reflect light from the second direction to a third direction. The lens has a third focal length and is operable to transmit light from the third direction. Further, the light transmitted by the lens is viewable by a user as a second image. Additionally, the perceived distance from the user to the second image is greater than a distance from the user to the lens.

A headset for augmented reality applications is provided. The headset includes at least one eyepiece configured to provide a see-through image to a user via a transparent optical component, and to provide an artificial image through a display, and a dimming shutter configured to adjust a transparency level of the transparent optical component. The dimming shutter further includes an active liquid crystal layer configured to adjust a transparency level according to an electrical power provided between two electrodes, and a photoactive layer configured to adjust the transparency level upon absorption of an ultraviolet radiation for a selected period of time. A default orientation of a host material in the active liquid crystal layer may be in a dark state or in a clear state, when no electrical power is provided. A method and a memory storing instructions to execute the method for use of the above device are also provided.

A projection arrangement for a head-up display (HUD), includes a composite pane, which includes an outer pane and an inner pane joined to one another via a thermoplastic intermediate layer and has an HUD region; an electrically conductive coating on the surface of the outer pane or the inner pane facing the intermediate layer or within the intermediate layer; and an HUD projector, which is directed at the HUD region; wherein the radiation of the projector is p-polarised, wherein the electrically conductive coating includes a first dielectric layer or layer sequence, a first electrically conductive layer, a second dielectric layer or layer sequence, a second electrically conductive layer, a third dielectric layer or layer sequence, a third electrically conductive layer, a fourth dielectric layer or layer sequence, a fourth electrically conductive layer, and a fifth dielectric layer or layer sequence.

A wireless position tracking device, a display system, and a wearable device are provided. The wireless position tracking device includes a rigid body, point light sources, a motion sensor, and a wireless transmission module. The rigid body has an inner concave surface, a head, a connecting portion, and a tail. The connecting portion connects the head and tail. The point light sources are fixed to positions outside the inner concave surface. The motion sensor locates in the rigid body for sensing a motion thereof and generating motion information. The wireless transmission module locates in the rigid body and electrically connects the motion sensor for wirelessly transmitting the motion information to the head-mounted device. An image capturing module of the head-mounted device captures a pattern formed by the point light sources. The head-mounted device calculates a relative position of the wireless position tracking device according to the pattern and motion information.

While head-mountable devices can provide immersive experiences, a user wearing a head-mountable device can also benefit from activities that include body motion and promote the user's health. Because such activities may not be intrinsically necessary to the operation of head-mountable devices, it can be beneficial to provide additional or modified operations that allow a user to continue operation of a head-mountable device while performing the desired body motions. The head-mountable device can detect movement and/or stasis of the user and determine whether motion would be recommended. Upon determining that motion, an additional motion, or a different motion would be beneficial, the head-mountable device can provide an output to the user that promote such motions. The output can include a notification to the user and/or a modification of the user interface that encourages the user to move in a particular way.

A head-up display device and a transportation device are provided. The head-up display device includes a light source, a scanner configured to scan light emitted from the light source to form scanned light, an angle adjuster configured to change an exit angle of the scanned light, a display unit configured to form an image according to the scanned light from the angle adjuster, and a projection assembly configured to project the image formed on the display component to a selected area.

A system for displaying a stereo image is disclosed. The system includes a stereoscopic head up display (HUD) that includes a combiner and a display configured to display a stereo image. The system further includes either a head tracking sensor or an eye tracking sensor configured to generate a tracking dataset. The system further includes a processor and a memory with instructions that cause the processor to receive the tracking dataset, generate a distortion map based on the tracking dataset and a distortion function, receive a media stereo image, generate a stereo signal based on the distortion map and the media stereo image, and transmit the stereo signal to the display. The system is capable of conveying an image to an operator in the absence of a relay lens.

A head up display system presents information to a human driver of a motor vehicle such that the presented information is superimposed on a windshield of the motor vehicle. An image capturing device captures an image of a scene in front of the vehicle that is representative of a background against which the information is presented to the driver. An electronic processor receives signals from the image capturing device indicative of the captured images of the scene in front of the vehicle. The processor determines, based on a color of the presented information and the signals from the image capturing device, whether the presented information is readable by the driver. If it is determined that the presented information is not readable by the driver, then a color of the presented information is changed so as to make the presented information more readable by the driver.

An information display apparatus and an information display method configured to display video information of a virtual image on a windshield of conveyance is provided. The information display apparatus includes: a display configured to display the video information; and a virtual image optical system configured to display a virtual image at a front of the conveyance by reflecting light emitted from the display by means of the windshield. The virtual image optical system includes a concave mirror and an optical element. A reflective film is formed on a reflecting surface of the concave mirror. A protective film for preventing moisture absorption is formed on a facing surface. By forming end surfaces of the two surfaces as a curved surface or an inclined surface and forming them on the end surfaces to block moisture, moisture absorption of plastic is prevented.

To improve brightness of an image to be perceived by a user and enhance visibility there is provided a light guide plate including an incident diffraction grating which diffracts incident imaging light, an exit diffraction grating through which the imaging light goes out, and an intermediate diffraction grating existing in optical paths from the incident diffraction grating to the exit diffraction grating. In this light guide plate, a periodic linear corrugated pattern is formed as the incident diffraction grating, and when an imaginary line is established that passes through an incident point of imaging light onto the incident diffraction grating and is parallel with a periodic direction of the corrugated pattern, the intermediate diffraction grating has a first region on one side of the imaginary line and a second region on another side of the imaginary line.
