A user interface and a method for the inputting and outputting of information in the vehicle includes an image generation unit which generates a projected image. A means for gesture recognition is arranged as a means for detecting an input, and that a means for view detection and following is arranged such that the recognition of the viewing direction and an association of the viewing direction of the driver with an area in the vehicle is carried out. Information about this area is generated in the viewing direction in the form of a projected image and is displayed floating over the area. Recognition of gestures of the driver is carried out. Upon a coincidence of a position of a hand of the driver, detected by the gesture recognition, with the projected image or a component of the projected image, a signal is generated by the central control unit and outputted.

A user interface and method for inputting and outputting information in a vehicle provides a user interface with a three-dimensional operating element. A laser projection unit generates at least one virtual three-dimensional operating element. A means for gesture recognition as a means for detection of an input are arranged in the interior of a vehicle. At least one virtual three-dimensional operating element is projected in the visual range of a driver by means of a laser projection arrangement. A gesture of the driver is detected by a gesture recognition means. A position of a hand of the driver is detected by means of the gesture recognition that coincides with an area of the virtual operating element. A signal for controlling a vehicle system or a function of a vehicle system is generated by the central control and evaluation unit and is output to the corresponding vehicle system.

According to one embodiment, when displaying an image on a display panel, projecting an image which is displayed on the display panel, inclining the image which is projected from the display panel at a predetermined angle of bend, and reflecting the image which is projected from the display panel via a prism and guiding the image to a projection surface, a display device corrects input picture image of the prism based on characteristics contrary to the chromatic aberration characteristics of the prism.

A vehicle may include a display for producing a hologram. The display may include a backlight unit for showing visual content. The display may include an instrument cluster. The instrument cluster may include one or more gauges, such as one or more graphical gauges, analog gauges, or hybrid gauges. The visual content may be in addition to and separate from the hologram. The display may include an illumination frame positioned in front of the backlight unit. The illumination frame may include one or more light elements. The display may include a holographic layer positioned in front of the backlight unit. The holographic layer may include a plurality of holographic layers. The one or more light elements may be configured to emit light through the holographic layer to produce the hologram.

Systems, methods, and articles of manufacture for autostereoscopic imaging in a vehicle provide for an enhanced viewer experience. In one example, a reflector is positioned to receive an image from a projector and reflect the image onto a viewing surface through which an external scene is visible, and a camera is positioned relative to the viewing surface to observe the external scene. The system determines first and second viewing distances and viewing angles from the viewing surface to respective first and second eyes for a viewer; produces first and second sub-images for viewing at the respective eyes based on an image; and projects the first and second sub-images from the projector to the reflector to reflect the sub-images to the respective first and second positions on the viewing surface, wherein the positions are set according to the viewing distances and angles to provide a 3D image to the viewer.

A display device for displaying images conveying depth information comprises a first display unit for representing first image information on a first screen. The first display unit comprises the first screen with a holographic optical element, HOE, provided thereon, and a first light source for providing light for illuminating the first screen. The display device further comprises a second display unit for representing second image information. The second display unit comprises a second light source for providing light with a plurality of predetermined discrete wavelengths for creating the second image information, and a second screen which is provided in parallel or oriented at an acute angle relative to the first screen in order to project the second image information onto the first screen and thereby generate a virtual image corresponding to the second image information behind the first screen.

There is provided a head-up display for a vehicle. The head-up display has a first housing and a second housing. The first housing comprises a picture generating unit and optical system. The second housing comprises a substantially flat cover glass and a layer. The picture generating unit is arranged to output pictures. The picture generating unit comprises a light source and a spatial light modulator. The light source is arranged to emit light. The spatial light modulator is arranged to receive the light from the light source and spatially-modulate the light in accordance with computer-generated light-modulation patterns displayed on the spatial light modulator to form a holographic reconstruction corresponding to each picture. The optical system is arranged to receive the pictures output by the picture generating unit and relay the pictures using an optical combiner to form a virtual image of each picture. The optical combiner combines light output by the picture generating unit with light from a real-world scene to present combined images to a viewer within an eye-box. The second housing is disposed between the first housing and optical combiner. The substantially flat cover glass is arranged to protect the first housing. The layer is arranged to change the trajectory of light such that any sunlight reflected by the cover glass is deflected away from the eye-box.

A display apparatus includes a display board and at least one image generating device. The display board has at least one display region, which includes a substrate, a decorative film, and a holographic optical element film. The decorative film is disposed on one side of the substrate. The holographic optical element film is disposed in at least one of the at least one display region, and disposed on another side of the substrate relative to the decorative film. The substrate is disposed between the decorative film and the holographic optical element film. The at least one image generating device is configured to project image light toward the holographic optical element film. The holographic optical element film is disposed between the substrate and the image generating device. The holographic optical element film converts the image light into display light, and transmits the display light toward the substrate.

A projection system is provided, and includes: a phase compensation apparatus (101), configured to perform first phase compensation and chromatic aberration correction on a light ray of a received image, and reflect an output light ray of the image to a holographic combiner (102); and the holographic combiner (102), configured to perform second phase compensation on the light ray that is of the image and that is output by the phase compensation apparatus (101). The phase compensation apparatus (101) is utilized to correct at least one of the following aberrations: astigmatism, a spherical aberration, and a coma aberration; and further correct another aberration in combination with the holographic combiner (102), thereby effectively eliminating aberrations and improving imaging quality. The projection system is used in a head-up display system, an augmented reality display system, a head-mounted display device, and the like.
