Abstract: There are included a vehicle behavior estimating unit (10) that estimates behavior of a vehicle (1); pattern illuminating units (4a to 4d) that illuminate a projection pattern onto ground around the vehicle (1); and an illumination control unit (11). The illumination control unit (11) controls the pattern illuminating units (4a to 4d) to illuminate a projection pattern, on the basis of the behavior of the vehicle (1) estimated by the vehicle behavior estimating unit (10).

Abstract: When information regarding a situation inside and outside a vehicle is determined to match a display change condition, a control unit (32) changes a display mode of information displayed outside the vehicle by controlling a projector device (4a) or a body light device (4b).

Abstract: A pairing display device includes a detection processing unit for detecting a user who is paired with a movable object having a display unit and a detection unit, by using the detection unit, and an output processing unit for, when the user is detected by the detection processing unit, displaying information showing that the user is paired with the movable object on a floor in the vicinity of the movable object, by using the display unit.

Abstract: A passenger guidance device is configured to include: a passenger detection unit for detecting a passenger who has entered a boarding waiting area which is an area in front of an entrance door of an elevator; a position detection unit for detecting a position of a passenger detected by the passenger detection unit; a number assignment unit for assigning a number indicating a boarding order to the elevator to the passenger detected by the passenger detection unit every time the passenger detection unit detects a passenger; and a number display unit for displaying the number assigned by the number assignment unit on a floor surface around the position detected by the position detection unit.

Abstract: When information regarding a situation inside and outside a vehicle is determined to match a display change condition, a control unit (32) changes a display mode of information displayed outside the vehicle by controlling a projector device (4a) or a body light device (4b).

Abstract: A second light device (4b) starts emission of a light pattern B after a first light device (4a) has started emission of a light pattern A. Elements included in the light pattern B and an element included in the light pattern A are arranged on the same straight line.

Abstract: A rear-road surface illumination apparatus is provided which includes: an avoidance determiner 30 to determine whether to provide a display to induce a following vehicle to avoid a vehicle, on the basis of vehicle information; and a controller 9 to cause an illumination light 10 to illuminate a rear road surface with light having illumination information that induces the following vehicle to avoid the vehicle when the avoidance determiner 30 determines to provide a display to induce the following vehicle to avoid the vehicle. Therefore, the rear-road surface illumination apparatus can indicate the existence of the vehicle to the following vehicle, to give the existence of the vehicle prominence, and can also make it easy to notify the driver of the following vehicle about what the driver of the vehicle desires the driver of the following vehicle to do.
