A display region has a curved surface shape having upper and lower end portions disposed at positions closer to a visual field than a reference plane, and a central portion disposed at a position farther from the visual field than the reference plane. A first convergence angle difference between a convergence angle from the eye position to the upper end portion and a convergence angle from the eye position to a first point on the reference plane through the upper end portion, a second convergence angle difference between a convergence angle to the central portion and a convergence angle to a second point on the reference plane through the central portion, and a third convergence angle difference between a convergence angle to the lower end portion and a convergence angle to a third point on the reference plane through the lower end portion respectively fall within four milliradians.

An HMI control device, which controls an HMI device mounted on a vehicle. The HMI device presents information to a driver of the vehicle in a recognizable manner. The vehicle is capable of automated driving and travels following a preceding vehicle at a speed equal to or lower than a predetermined speed. The HMI control device is configured to: present attention information for calling attention of the driver when a congestion is determined to be cleared; acquire a behavior of the driver; and end a second task presented on the HMI device at an end timing corresponding to the behavior of the driver acquired after presentation of the attention information.

A device that uses brainwave activity to allow a user to perform hands-free tasks is disclosed. For example, the device can include a transparent display, an electroencephalogram (EEG) sensor, and a processing circuitry coupled to the transparent display and the EEG sensor. The EEG sensor can be configured to sense an EEG signal corresponding to brain activity associated with a user of the device. The processing circuitry can be configured to display a visual stimulus on the transparent display and generate a control signal associated with a task of the user based on the EEG signal. Therefore, the user can use his brainwave activity to perform hands-free tasks.

A method for operating a display unit of vehicle, wherein the display unit displays at least one display, comprises ascertaining the viewing direction of a driver using a gaze-tracking device; checking whether the viewing direction of the driver is directed at the display unit; checking whether traffic-relevant data are present; operating the display unit in an energy-saving mode when the view of the driver is not directed at the display unit and/or when no traffic-relevant data is present; and operating the display unit in a display mode when the view of the driver is directed at the display unit and/or when traffic-relevant data is present for display. A display unit is also disclosed.

In the case in which a loss of the viewpoint position of a driver occurs when a viewpoint position follow-up warping control is executed to update warping parameters according to the viewpoint position of the driver, and then the viewpoint position is re-detected, it is suppressed that the appearance of an image instantaneously changes in accordance with the update of the warping parameters and the driver is caused to feel uneasy. When the viewpoint loss in which at least one position of the right and left viewpoints becomes unclear is detected, a control unit, which executes the viewpoint position follow-up warping control, maintains, in a viewpoint loss period, the warping parameters set immediately before the viewpoint loss period, and, when the viewpoint position is re-detected after the viewpoint loss period, invalidates at least one warping process using the warping parameters corresponding to the re-detected viewpoint position.

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.

The various embodiments set forth a method for displaying information on one or more surfaces of a vehicle, the method comprising acquiring position data associated with a driver of the vehicle, calculating a current field-of-view of the driver based on the position data, determining a suitable surface for displaying visual information within the vehicle based on the current field-of-view of the driver, and projecting an element of visual information on the suitable surface.

A head up display apparatus includes: an image display apparatus having a light source and a display element and forming an image; an image-light projecting means displaying a virtual image onto a forward part of a vehicle by projecting the image light emitted from the image display apparatus to be reflected on a windshield 3; and a point-of-view detecting system 6 sensing a point of view of the driver. In the head up display apparatus, the image-light projecting means includes a means generating illumination light entirely made of single-color visible light emitted to a face of the driver in a predetermined state of the vehicle.

A method and apparatus for outputting a three-dimensional (3D) image are provided. To output a 3D image, a stereo image is generated based on viewpoints of a user and rendered into a 3D image. Since the stereo image is generated based on the viewpoints of the user, the user views a different side of an object appearing in the 3D image depending on a viewpoint of the user.

An optical arrangement for a motor vehicle includes a head up display light field emitter that emits a light field. At least one mirror is positioned to reflect the light field such that the light field is again reflected by a windshield of the vehicle, and such that the light field is visible to a driver of the vehicle as a virtual image. The at least one mirror has a transparent section. A driver monitoring camera is positioned to capture an image of a face of the driver through the transparent section of the at least one mirror.
