Abstract: A display system for use in a mobile body includes an acquisition unit that acquires detection information of at least one detection object that exists in a target space, a display unit that displays a virtual image in the target space, and a controller that controls display of the display unit. In the target space, at least one detection area is provided. The at least one detection object includes a first detection object that exists closest to the mobile body and a second detection object that has the shortest time to collision with the mobile body. The controller determines, as a display object, at least one of the first detection object and the second detection object in the at least one detection object that exists in the detection area based on the detection information, and causes the display unit to display the virtual image corresponding to the display object.

Abstract: An image display system includes a body, a first correction unit, and a second correction unit. The body houses a display unit to display an image and projects a virtual image, corresponding to the image, onto a target space using outgoing light of the display unit. The first correction unit corrects for distortion of the image. The second correction unit corrects a display location of the image on the display unit in accordance with an orientation signal representing a change in orientation of the body. Each of divisional areas of a display screen of the display unit is assigned with a distortion correction parameter for correcting for the distortion of the virtual image. The first correction unit applies distortion correction to each of the image regions of the image on the display screen based on a distortion correction parameter assigned to a divisional area where the image region is displayed.

Abstract: An image display system includes a display unit displaying an image, a projection unit projecting in a target space a virtual image corresponding to the image with an output light of the display unit, a body unit provided thereto the display unit and the projection unit, and an image producing unit including a first correction unit and a second correction unit. The first correction unit performs a first correction processing of correcting, based on a first orientation signal indicative of a first orientation change of the body unit, a display position of the virtual image in the target space. The second correction unit performs a second correction processing of correcting, based on a second orientation signal indicative of a second orientation change of the body unit which is faster than the first orientation change, the display position of the virtual image in the target space.

Abstract: A display system includes a projector that projects a virtual image onto a target space to allow a target person to visibly recognize the virtual image and a controller that controls display of the virtual image. When the projector projects a virtual image corresponding to a caution object, the controller selects at least one reference point from one or more candidate points existing around the caution object and associates the virtual image with the at least one reference point.

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: 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: A display system includes a display unit which displays a virtual image in a target space, a controller which controls display of the display unit, and an obtaining unit which obtains vibration information about vibration applied to the display unit. The controller changes the display mode of the virtual image based on the vibration information, when the vibration exceeds a first threshold value and a viewing distance of the virtual image exceeds a second threshold value.
