A circuit device includes a storing section configured to store a rendering image and a warp processing section. The warp processing section includes a coordinate converting section, a coordinate-address converting section, and an output section. The coordinate converting section converts, with coordinate conversion based on warp parameters and rotation correction parameters, an output coordinate, which is a coordinate on a display image, into an input coordinate, which is a coordinate on the rendering image. The coordinate-address converting section converts the input coordinate into a read address of the storing section. The output section reads out pixel data of the rendering image from the read address of the storing section and outputs, based on the read-out pixel data, pixel data in the output coordinate of the display image.

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 disclosure is related to reducing shake and vibration in Head-Up Displays (HUDs) under dynamic operating conditions. The apparatus includes a curved mirror for projecting an image from a display unit on a windshield of a vehicle. The curved mirror has damping tape on its nonreflective side to absorb vibrational energy and shift the first natural frequency of the curved mirror to a higher frequency. The damping tape includes at least a viscoelastic adhesive layer and a constraining layer. The method for stabilizing the HUD includes applying damping tape selected and positioned to reduce vibrational amplitude and shift the first natural frequency of the curved mirror to a higher frequency.

Systems and methods for augmented-reality-based marine navigation. An electronic controller plots a navigational route between a current geospatial position of a host vessel and a target destination of the host vessel. The navigational route is plotted as a series of waypoints. The electronic controller receives an electronic transmission from at least one nearby ship indicative of a current position of the at least one nearby ship (e.g, an MS transmission) and updates the navigational route based at least in part on the received electronic transmission. A graphical representation of the updated navigational route and a graphical indication of the current position of the at least one nearby ship (e.g., a conformal overlay of the at least one nearby ship) are then displayed on a head-worn augmented reality display device.

A head-up display is configured to project an image on a transparent reflection member to cause an observer to visually recognize a virtual image, and includes a display device configured to display the image, and a projection optical system configured to project the image displayed by the display device as the virtual image for the observer. The projection optical system is configured to form an image as an intermediate image, and includes a first lens configured to condense light, and a first optical element configured to diffuse light. The first lens and the first optical element are disposed in this order along an optical path from the display device. The first lens is inclined with respect to a reference beam which is defined as a beam reaching a center of a viewpoint region of the observer and corresponding to a center of the virtual image.
