The present disclosure relates to apparatuses for display. An example display apparatus includes a picture generation unit, an imaging reflector, a detection unit, and at least one processor. The picture generation unit is configured to generate an image, and send image light of the image to the imaging reflector. The imaging reflector is configured to reflect the image light to generate a virtual image of the image. The detection unit is configured to collect first signal light transmitted through the imaging reflector, where the first signal light is light reflected by an eye of a user viewing the virtual image. The at least one processor is configured to determine a location of the eye of the user based on the first signal light collected by the detection unit, where a propagation direction of the image light reflected by the imaging reflector is parallel to a propagation direction of the first signal light.

A display control method for controlling displays of a first display device and a second display device included in a vehicle is provided. The display control method includes displaying, on the first display device, a transparent screen at a position where a driver is capable of viewing an outside of the vehicle through a windshield; locating a screen of the second display device at a position different from the screen of the first display device; and in a case that a line-of-sight position of the driver detected by a line-of-sight detection device included in the vehicle does not match the position of the screen of the second display device, controlling the display of the screen of the second display device more than the display of the screen of the first display device.

A method for operating a reflection display system for displaying a display image for a vehicle occupant of a motor vehicle by reflection of the display image on a reflection surface, in particular on a front windscreen, includes outputting a sequence of measurement display images with different patterns with different lighting intensities in some regions; detecting a brightness signal by an ambient brightness sensor while each measurement display image of the sequence is being displayed in order to obtain a brightness profile of the brightness signals; evaluating the profile of the brightness signals with respect to a predefined reference brightness profile which specifies brightness signals when the display surface is uncovered, for the sequence of measurement display images with constant ambient brightness; and signaling the presence of a foreign object on the display surface depending on the result of the evaluation.

A vehicle display device includes a display unit that emits display information to be visually recognized by a driver as display light, and an aspheric mirror that reflects the display light toward a windshield. The display unit emits the display light that is narrower than an eye range based on a distribution range of eye points of a plurality of drivers, and corresponds to an eye box, which is a light distribution range based on an acquired eye point.

A method and system for assisting a user when interacting with a graphical user interface combines gaze based input with gesture based user commands. A user of a computer system without a traditional touch-screen can interact with graphical user interfaces in a touch-screen like manner using a combination of gaze based input and gesture based user commands. A solution for touch-screen like interaction uses gaze input and gesture based input as a complement or an alternative to touch-screen interactions with a computer device having a touch-screen. Combined gaze and gesture based interaction with graphical user interfaces can be used to achieve a touchscreen like environment in computer systems without a traditional touchscreen or in computer systems having a touchscreen arranged ergonomically unfavorable for the user or a touchscreen arranged such that it is more comfortable for the user to use gesture and gaze for the interaction than the touchscreen.

Provided are an apparatus and method for monitoring driver's concentrativeness capable of monitoring whether a driver is concentratedly obtaining major information by tracing a driver's sight while a vehicle is running, in order to provide alarm to the driver when driver's concentrativeness is dropped at a time when the major information is changed while the vehicle is running.

The present disclosure relates to a head-up display with image distortion for a vehicle, which has an image signal source, an image distorter, a display unit and a mirror unit. According to the disclosure, the image signal source has a common output for image signals and configuration information, and the image distorter has a common input for image signals and configuration information.

A display apparatus for a vehicle is provided with a display unit and a display position control unit. The display unit is capable of displaying information at plural different display positions. In an autonomous driving state of the vehicle, the display position control unit detects a position of a steering wheel and an eye position of a driver. When the display position control unit determines that information displayed by the display unit is obscured by the steering wheel as seen by the driver, the display position control unit causes the information to be displayed at a display position that is visible to the driver.
