Abstract: A head-up display system of a vehicle visually transmits information to eyes of a first occupant and eyes of a second occupant. The system includes an illumination device emitting first and second display lights having first and second polarizations, respectively. The system includes a windshield and a holographic panel including first and second layers. The display lights emit toward the holographic panel at an entrance angle relative to an axis normal to the holographic panel. The first layer diffracts the first display light having the first polarization in a first exit direction at a first exit angle relative to the axis toward the eyes of the first occupant. The second layer diffracts the second display light having the second polarization in a second exit direction at a second exit angle relative to the axis, and different than the first exit angle, toward the eyes of the second occupant.

Abstract: A head-up display for displaying graphics upon a windscreen of a vehicle includes a graphic projection module for generating images upon the windscreen of the vehicle, a user input device for receiving user-generated commands created by a user of the vehicle, and one or more controllers in electronic communication with the graphic projection module and the user input device. The controller executes instructions to instruct the graphic projection module to generate a luminance adjustment graphic, where the luminance adjustment graphic includes an adaptive color palette graphic including two or more colors. The controller receives, from the user input device, a user-generated luminance input indicating a change in a level of luminance in a selected color, where the change in the level of luminance in the selected color is selected by the user to discern differences between the two or more colors caused by a color vision deficiency.

Abstract: A head-up display system of a vehicle visually transmits information to eyes of an occupant. The head-up display system comprises an illumination device configured to emit a display light and a windshield spaced from the illumination device and extending transverse to the display light. The head-up display system comprises a holographic panel coupled to and extending with the windshield and arranged to diffract the display light toward the eyes of the occupant. The display light emits toward the holographic panel in an entrance direction at an entrance angle relative to an axis normal to the holographic panel and diffracts away from the holographic panel in an exit direction at an exit angle relative to the axis, which is different than the entrance angle.

Abstract: A method includes placing a physical target on a windshield of a vehicle, mounting a fixture inside the vehicle to position a camera array on the fixture within a line of sight of a passenger, capturing images of the physical target using the camera array, and determining a difference between actual and target locations of the physical target in each image. In addition, the method includes controlling the HUD to display a virtual target on the windshield, capturing images of the virtual target using the camera array, and determining a target location of the virtual target in each image based on the difference. Further, the method includes determining an offset between an actual location of the virtual target in each image and the target location of the virtual target in each image, and adjusting the location of an image projected onto the windshield by the HUD based on the offset.

Abstract: A route recording with real-time annotation and re-display system includes a first automobile vehicle having one or more camera systems. An imaging display device defining a head-up display (HUD) is positioned within the first automobile vehicle and receives camera imaging data from the one or more camera systems. The HUD includes a video display screen presenting the camera imaging data either in real-time or re-displayed from a pre-recorded image file. A microphone array receives vehicle operator voice data of a first operator of the first automobile vehicle. An annotated-recorded-route is created by adding a user input of the first operator of the first automobile vehicle including the voice data. The annotated-recorded-route identifies specific coordinates or locations along a travel route driven by the automobile vehicle through the voice data after activating recording of the camera imaging data.

Abstract: An augmented reality head-up display system for displaying graphics upon a windscreen of a vehicle includes a controller in electronic communication with one or more non-visual object detection sensors, one or more image-capturing devices, and a graphic projection device. The controller executes instructions to receive a plurality of detection points that indicate a presence of an object from the one or more non-visual object detection sensors. The controller executes instructions to compare the plurality of detection points with the image data of the environment surrounding the vehicle to identify a visually imperceptible object located in the environment. In response to identifying the visually imperceptible object, the controller determines a notification symbol that signifies the visually imperceptible object. The notification symbol is overlaid at a position upon the windscreen where the visually imperceptible object would normally be visible.
