Abstract: An event prediction system includes an accumulation unit and a generator. The accumulation unit accumulates a plurality of pieces of learning data each including history information representing a situation of a mobile object upon occurrence of an event associated with driving of the mobile object. The generator generates a prediction model for prediction of relative coordinates of an occurrence place of the event relative to the mobile object by using the plurality of pieces of learning data. Each of the plurality of pieces of learning data further includes label information representing the relative coordinates of the occurrence place of the event relative to the mobile object.

Abstract: The driving assistance device acquires, from an autonomous driving controller that determines an action of a vehicle during autonomous driving of the vehicle, action information indicating a first action that the vehicle is caused to execute. The driving assistance device acquires, from a detector that detects a surrounding situation and a travel state of the vehicle, detection information indicating a detection result. The driving assistance device determines a second action which is executable in place of the first action, based on the detection information. The driving assistance device generates a first image representing the first action and a second image representing the second action. The driving assistance device outputs the first image and the second image to a notification device such that the first image and the second image are displayed within a fixed field of view of a driver of the vehicle.

Abstract: A screen includes a surface inclined with respect to a reference plane. A driver moves the screen in a movement direction orthogonal to the reference plane. When forming a first virtual image serving as a virtual image on a first virtual plane whose inclination angle α with respect to an optical axis of a projector is smaller than a predetermined value, a controller is configured to hold the screen in the movement direction. When forming a second virtual image serving as the virtual image on a second virtual plane whose inclination angle β with respect to the optical axis of the projector is larger than the predetermined value, the controller is configured to move the screen in the movement direction.

Abstract: An information display device includes a surrounding environment detector, a vehicle information acquirer, a predictor, an avoidance path provider, and an information display. The surrounding environment detector detects position relevant information related to a position of at least a surrounding object in a surrounding environment of a vehicle. The vehicle information acquirer detects vehicle information including a speed and a steering direction of the vehicle. The predictor predicts a contact of the vehicle with the surrounding object, based on the position relevant information and the vehicle information. When the predictor has predicted that there is a possibility of the contact of the vehicle with the surrounding object, the avoidance path provider assumes an avoidance path for avoiding the contact, based on the position relevant information and the vehicle information. The information display displays the avoidance path.

Abstract: A head-up display includes an optical system that radiates light forming a projected image toward an eye box. The eye box is a predetermined range in which eyes of an observer are assumed to be present. The optical system includes a Fresnel lens having a bumpy surface having a sawtooth-shaped cross-section. The bumpy surface is formed concentrically around an optical axis, and formed by alternately disposing first surfaces as light condensing surfaces that allow incident light to converge toward a focal point, and second surfaces as wall surfaces that do not allow the incident light to converge toward the focal point. The second surfaces are inclined with respect to the optical axis of the Fresnel lens at an angle to reflect the incident light striking the wall surfaces, in a direction toward outside of a range of the eye box.

Abstract: To provide a display device that can suppress generation of a double image. Display device includes plate-shape windshield having translucency and a projection unit that projects light expressing an image onto windshield such that the light is reflected toward a user by windshield. The projection unit changes a display distance between an eye of the user and a position of an image visually recognized as a virtual image by the user through windshield by the light projection. Windshield is formed such that a wedge angle that is of an angle formed between a front side and a back side at a region located at any level of windshield is continuously decreased with increasing level.

Abstract: A display apparatus that displays a virtual image having a shape that follows an object to be superimposed when viewed from a user is provided. An optical system that is included in the display apparatus and displays a virtual image that is three-dimensional includes a laser that emits laser light, a MEMS scanner that performs scanning with the laser light, a screen that forms an image on a surface of the screen with the MEMS scanner scanning the surface with the laser light, a projection unit that generates a virtual image by projecting the image formed onto a display medium, and a drive unit that reciprocates the screen scanned with the laser light in a predetermined section along an optical path of the optical system at a predetermined cycle. The MEMS scanner changes a vertical movement speed of a scan line according to a shape of an object included in a background and is superimposed with the virtual image in scanning performed with the laser light at a scanning cycle in synchronization with a cycle of the reciprocation.
