A head up display arrangement for a motor vehicle includes a driver-monitoring camera capturing images of a human driver of the motor vehicle. A picture generation unit emits a light field such that the light field is reflected by a windshield of the vehicle so as to be visible by a human driver of the motor vehicle as a virtual image. An electronic processor is communicatively coupled to the driver-monitoring camera and to the picture generation unit. The electronic processor receives the images captured by the driver-monitoring camera and determines, dependent upon the captured images, an element in the virtual image at which eyes of the human driver are looking. The electronic processor controls the picture generation unit to increase a relative brightness of the element in the virtual image at which eyes of the human driver are looking as compared to brightnesses of other elements in the virtual image.

The present invention is to achieve a HUD display that is easy for an occupant to see while reducing a sense of discomfort by limiting obstruction of actual scene visibility. A display control device 700 includes a control unit 701 that controls a visibility level and a display state of a display object, wherein, in a case of performing a low-visibility process for setting the visibility level of the display object to a second visibility level lower than a first visibility level, the control unit performs a display object recognizability improvement process that includes at least one of the following: increasing the number of display elements 300, 302, 304 forming the display object compared to the case in which the first visibility level is set; and expanding the size of some or all of the display elements forming the display object compared to the case in which the first visibility level is set.

A display method includes obtaining image information, where the image information includes an eye of a first user, determining an eye position and a line-of-sight direction of the first user based on the image information, and adjusting a display manner of a first area in a display area based on the eye position and the line-of-sight direction of the first user. The display area is a display area of a head-up display or a display area of an augmented reality head-up display, and the first area includes privacy information of a second user.

An enhanced reality system for a vehicle having an enhanced reality headset with a headset display, control unit, and power source. The enhanced reality headset displays a video of an upcoming road segment with one or more pieces of supplemental display information. One potential drawback of such a system involves blind spots within a display area, referred to as visual impairment zones, which are unique to each driver. The enhanced reality system and method disclosed herein are configured to administer a vision test for each driver, identify any visual impairment zones unique to that driver, determine if any pieces of supplemental display information fall within a visual impairment zone and, if so, move the supplemental display information out of the visual impairment zone so that it is more visible to the driver. An enhanced reality profile may be maintained for each driver.
