A method of operating virtual reality glasses in a vehicle in which a risk of motion sickness for a wearer of the virtual reality glasses is reduced with the aid of the method. A virtual reality system (IO) includes the virtual reality glasses and the vehicle. According to the method, a vehicle movement of the vehicle is evaluated in such a way that ultimately, after the image data describing the virtual surroundings have been split into a background image dataset and a foreground image dataset, a lateral offset for a position of an object in the foreground in comparison with the background is determined, so that virtual surroundings which are processed in this way can be determined and displayed. Alternatively, the virtual surroundings can be enlarged in accordance with the vehicle movement, and processed virtual surroundings can be determined by means of a movement of the enlarged virtual surroundings along a movement trajectory, and displayed.

The present invention relates to a video output device mounted on a vehicle to implement augmented reality, and a method for controlling the same. The video output device comprises: a video output unit for outputting visual information for implementing the augmented reality; a communication unit for receiving a front video captured of the front of the vehicle; and a processor for investigating, in the front video, at least one to-be-driven lane on which the vehicle is to be driven, and controlling the video output unit such that main carpet images guiding the to-be-driven lanes are output lane by lane.

A head-up display device that is configured to allow a driver to intuitively recognize a plurality of objects sequentially along a travel route of a vehicle while projecting a video onto an image forming plane that has a length in the vertical direction shorter than a length in the horizontal direction. An optical processor of the head-up display device obtains from a controller a first image signal based on the nearest road sign information and a second image signal based on the following road sign information along the travel route. The optical processor causes line segment objects as well as information objects generated from the first image signal and the second image signal, respectively, to be displayed on an image forming plane.

A vehicle driving assistance device includes: a sensing unit configured to capture a front image of a running vehicle; a processor configured to detect a lane by using the front image and estimate the lane by detecting objects around a road, on which the vehicle is running, by using the sensing unit; and an output unit configured to output the estimated lane.

A mirror device includes: a mirror including a rotation shaft pivotably supported, a coupling shaft separated from the rotation shaft, and a reflecting surface that reflects display light; a coupling member including a first coupling portion coupled to the rotation shaft and a second coupling portion coupled to the coupling shaft, and configured to pivot integrally with the mirror; a motor that is connected to the coupling member via a gear and that pivots the coupling member; and a first spring having one end side immovably fixed and another end side coupled to the coupling member, and configured to apply force to the coupling member in one rotation direction.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cab installed on the upper turning body, a display device installed in the cab, and image capturing devices attached to the upper turning body. The display device is configured to simultaneously display a left mirror image and a right mirror image generated based on an image captured by at least one of the image capturing devices. The left mirror image is an image corresponding to a mirror image in a left mirror attached to the left front end of the shovel. The right mirror image is an image corresponding to a mirror image in a right mirror attached to the right front end of the shovel.

Provided is a display apparatus for a three-dimensional (3D) head-up display (HUD), the display apparatus including a transparent substrate, a polarizing film layer provided on the transparent substrate, and a lenticular lens provided on the polarizing film layer opposite to the transparent substrate, wherein the lenticular lens includes an adhesive layer, a base substrate provided on the adhesive layer, and a pattern layer provided on the base substrate opposite to the adhesive layer.

A heads up display (HUD) includes a display source for emitting an emitted image, a windshield and an absorbing polarizer. For substantially normally incident light, the absorbing polarizer substantially transmits the incident light polarized along a pass direction, and substantially absorbs the incident light polarized along a block direction. The emitted image includes at least one image ray that is received and transmitted by the absorbing polarizer toward the windshield at a first location of the absorbing polarizer. The transmitted image ray is received and reflected by the windshield at a second location of the windshield. A first normal line of the absorbing polarizer at the first location is substantially parallel to a projection of the transmitted image ray onto the windshield. Further, the pass direction of the absorbing polarizer at the first location is substantially parallel to a second normal line of the windshield at the second location.

According to some embodiments of the disclosure, an AR-content-providing apparatus includes display modules configured to display AR content images on windows of a vehicle, at least one sensing module configured to generate image data obtained by capturing surroundings of the vehicle, and configured to generate distance sensing signals corresponding to distances to objects and people outside the vehicle, and a control module configured to generate AR content corresponding to driving information and surrounding information of the vehicle using the image data and the distance sensing signals, and configured to control the display modules and at least one electronic device to display the AR content.

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.
