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 video display system includes: a screen on which an mage for displaying a virtual image is projected; a light source that emits laser light; a scanner that projects the image onto the screen by biaxially scanning the laser light onto the screen; and a controller that generates the image and controls the light source using an image signal for causing the generated image to be projected onto the screen by the laser light, and receives an input of sensing information measured using a temperature sensor and controls the scanner in accordance with the input sensing information. When the sensing information indicates a temperature outside a given temperature range, the controller causes the scanner to reduce an amplitude of the biaxial scanning in at least one axial direction to a smaller value than when the sensing information indicates a second brightness or a temperature within the given temperature range.

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: A display system according to an aspect includes a screen, a drive control unit, and a projection unit. The drive control unit has the screen moved in a movement direction. The projection unit renders an image on the screen by irradiating the screen with a light beam that scans the screen and projects a virtual image onto a projection plane with the light beam transmitted through the screen. The drive control unit has the screen moved in the movement direction such that an optical path leading to a rendering point on the screen varies its length according to a tilt angle defined by the projection plane with respect to a reference plane.

Abstract: An information processing system that appropriately estimates a driving conduct includes: a detector that detects a vehicle environment state, which is at least one of surroundings of a vehicle and a driving state of the vehicle; a behavior learning unit configured to cause a neural network to learn a relationship between the vehicle environment state detected by the detector and a behavior of the vehicle implemented after the vehicle environment state; and a behavior estimation unit configured to estimate a behavior of the vehicle by inputting, into the neural network that learned, the vehicle environment state detected at a current point in time by the detector.

Abstract: An information communication terminal includes the followings. An input receiving unit receives an input from a user. A communication unit obtains presentation information corresponding to an input by the user from a server according to a dialogue scenario, every time the input is received. A dialogue processing unit presents the user with the presentation information obtained by the communication unit. A communication state determination unit determines a communication state between the communication unit and the server. When the communication state determination unit makes a first determination that the communication is deteriorated during a dialogue, the dialogue processing unit causes the communication unit to obtain, as candidate presentation information, at least one presentation information with a possibility of being presented to the user after the first determination according to the dialogue scenario.
