Tracking means is utilised to determine a relative location of eyes of at least one user with respect to an optical combiner. The optical combiner is arranged on an optical path of a display unit and on an optical path of real-world light emanating from a real-world environment. A display image is generated, based on a curvature of a light-emitting surface of the display unit, a relative location of the optical combiner with respect to the display unit, and the relative location of the eyes of the at least one user with respect to the optical combiner. The display image is displayed via the display unit. The optical combiner is employed to reflect light emanating from the light-emitting surface of the display unit towards the eyes of the at least one user, whilst optically combining said light with the real-world light.

A picture generation unit emits a light field. A mirror reflects the light field toward a windshield of a motor vehicle such that the light field is reflected off of the windshield and is visible to the driver as a virtual image. An infrared emitter transmits infrared energy through the mirror such that the infrared energy is substantially co-axial with the light field, and such that the infrared energy is reflected off of the windshield toward the human driver. An infrared camera captures infrared images based on the transmitted infrared energy reflected off of the human driver and received by the infrared camera. Eye tracking is performed based on the captured infrared images. The infrared energy is transmitted at a higher power level at a beginning of the eye tracking than after the beginning of the eye tracking.

An agricultural work machine and a method for operation an agricultural work machine are disclosed. The agricultural work machine includes a driver's cab with an interior space spatially partially delimited by a front window and at least one side window, a driver's seat arranged in the interior space, an input device for entering input by an operator, a visualization system for visualizing information for an operator sitting on the driver's seat, and a control device which is communication with the visualization system. The control device controls the visualization system in such a way that process information relevant to the selected work process is visualized.

Methods, systems, and apparatuses for outputting situation-dependent, expanded warning information in a driver assistance system of a vehicle. The driver assistance system outputs situation-contingent, expanded warning information in the vehicle. A registration unit registers an output of warning information in an information-output unit of the vehicle. A sensor ascertains a degree of attentiveness of a driver of the vehicle. An electronic control unit controls an output in the vehicle such that, where a low degree of attentiveness of the driver has been ascertained, the output provides an expanded output of warning information in the vehicle.

Embodiments are disclosed for display configurations for providing an augmented reality heads up display. In one example, a method of operating a display system includes adjusting an output of image light from a display to pass through an optical element positioned between the display and at least one micro lens array, including impinging light upon a transparent plane to generate a three-dimensional image on a continuous plane that is based on a user focal point determined by an eye-tracking module.

According to at least one aspect, the present disclosure provides a head-up display (HUD) configured to display information on a windshield of a vehicle, comprising: a picture generation unit (PGU) configured to individually output a first image for a driver's left eye and a second image for a driver's right eye; a reflection unit configured to reflect, toward the windshield, the first and second images output from the PGU; and a controller configured to control the PGU to output the first and second images alternately.

An assistance system includes: an augmented reality module configured to i) determine a path of a host vehicle, ii) detect one or more objects with one or more trajectories predicted to interfere with the path of the host vehicle, and iii) based on the one or more trajectories, generate a first digital gateway indicative that the host vehicle should yield for the one or more objects; a display control module configured to control an augmented reality head-up display to display the first digital gateway in a closed state over an environment forward of the host vehicle and along the path of the host vehicle; and a vehicle control module configured to yield to the one or more objects as the host vehicle approaches the first digital gateway.
