A system includes a camera aimed externally to a vehicle, a window of the vehicle, a projector positioned to project on the window, and a computer communicatively coupled to the camera and the projector. The computer is programmed to, upon receiving data from the camera indicating a first person outside the vehicle, instruct the projector to project an image on the window depicting a second person inside the vehicle.

Disclosed are a drunk driving prevention system and a method of controlling the system that includes a sensor module measuring a alcohol content in the exhaled breath of a driver during a breath-checking of the driver and a control module configured to check the intoxication state of the driver from the alcohol content measured by the sensor module to determine whether the breath-checking is complete and block an engine start when the breath-checking fails, wherein the control module includes a check unit displaying breath-checking guide information through a display unit and the check unit displays the breath-checking guide information based on an engine start input of the driver.

Systems and methods for controlling a head-up display (HUD) in a vehicle are disclosed herein. One embodiment deactivates the HUD in response to a command from a driver of the vehicle; assigns a level of urgency to an item of information associated with a current vehicular context; and activates the HUD to display the item of information to the driver, when the level of urgency exceeds a predetermined threshold.

A display controlling device includes a position detecting unit for detecting a position of the head of a driver and a position of an eye of the driver; a region adjusting unit for adjusting the position of a region, to be displayed on a display, in an outside image, depending on the detection result by the position detecting unit; and a display controlling unit for displaying, on the display, a region corresponding to the region of the position adjusted by the region adjusting unit. When there is a change in the position of the head so as to move in both the vertical direction in the crosswise direction of the vehicle, the region adjusting unit prevents adjustment of the position of the region to a position corresponding to the change, in the vertical direction, of the position of the eye, and adjusts the position of the region to a position corresponding to a change in the position of the eye in the crosswise direction and/or the front/rear direction.

An electronic device for displaying data on a display screen, the device being connectable to the display screen and to an image sensor, the image sensor being operable to capture at least two images of a user. The electronic device includes: a module for displaying data, in particular icons, on the display screen; a module for detecting, via the at least two images taken, a movement towards the screen by at least one finger of the user, and then for calculating a direction of the movement; a module for determining, from a page displayed on the screen and depending on the direction of movement, an area of the screen corresponding to the direction; and a module for controlling an enlargement of the area when the at least one finger approaches the screen.

A human machine interface control unit as an information presentation control device is used in a vehicle having an autonomous driving function to perform a driving action on behalf of a driver, and controls an information presentation device configured to present information to the driver. The human machine interface control unit includes a permissible action determination unit configured to determine a permissible action that a driver is permitted to take among actions, other than a driving action, to be possibly taken by the driver when the autonomous driving function is implemented, and an information presentation content control unit configured to cause an information presentation device to present information related to a determination result of the permissible action.

Provided is a vehicle display device that includes: an image display unit that emits display light of an image; an optical system that projects the display light emitted from the image display unit toward a reflection face in front of a driver; and a controller that controls the image display unit. The image has a first region that is a region viewed by both eyes of the driver and a second region that is a region of the image on an end part side in an image lateral direction relative to the first region. In a case where a graphic image included in the image is across a boundary between the first region and the second region, the controller executes blur processing on the graphic image.

A method for controlling an autonomous vehicle is disclosed. The vehicle control method, which adjusts a seat installed in a vehicle, a first display positioned in front of the seat and facing the seat, and a second display positioned in front of the first display and facing the seat, includes: detecting the face of a passenger sitting in the seat by a camera installed in the vehicle; estimating the face height from the floor surface of the vehicle; if the estimated face height is lower than a predetermined level, setting a display region on the first display, and, if the estimated face height is higher than the predetermined level, setting the display region on at least part of the second display; and displaying images in the set display region. One or more among an autonomous vehicle, user terminal, and server according to the present invention may be associated with an artificial intelligence module, a robot, an augmented reality (AR) device, a virtual reality (VR) device, etc.

An anti-motion sickness device for a motor vehicle includes a triaxial accelerometer to detect vehicle accelerations along three axes and to emit a corresponding acceleration signal; a display component of light markers to form two artificial horizon lines at two inner surfaces, respectively of the vehicle. The horizon lines are perpendicular or substantially perpendicular to each other. The device includes a control unit for receiving the acceleration signals emitted by the accelerometer and capable of driving the display component such that the horizon lines are aligned in a horizontal plane, perpendicular or substantially perpendicular to the gravity vector regardless of vehicle accelerations. The position of the horizontal plane along a direction parallel to the gravity vector varies as a function of a physical parameter related to the person sitting in the vehicle by being positioned adjacent the first inner surface and in front of the second inner surface.

A waveguide head-up display (HUD) includes a waveguide that includes a lower surface and an upper surface and is configured to receive an input and project, based on the input, at least one image from the upper surface and into an eyebox, and a prism arranged at least one of on and above the waveguide. The prism includes a lower surface facing the waveguide and configured to receive the at least one image and an upper surface opposite the lower surface configured to project the at least one image received via the lower surface of the prism. The upper surface of the prism is angled relative to the upper surface of the waveguide such that a first normal of the upper surface of the prism is different from a second normal of the upper surface of the waveguide.
