Abstract: An actuator of an airbag device includes a main body portion, which is attached to an attachment base, and a cap including a fitting protruding portion that is inserted into a fitting recessed portion of the main body portion. The fitting protruding portion has a holding portion, which is inserted into a holding hole of a coupling member when fitted to the main body portion and holds a leading end portion of the coupling member, and a movement permitting unit that, when a ceiling portion of the cap is subjected to pressure of a combustion gas of a squib, causes the ceiling portion to move, and causes the holding portion to move from a holding position, wherein the holding portion is inserted into the holding hole of the coupling member, to a holding released position, wherein the holding portion is removed from the holding hole.

Abstract: A projector apparatus includes a projection unit and a controller. The projection unit projects projection video of an image at a set angle of view on a projection surface in accordance with a video signal indicating the angle of view of the image including an object. The controller performs video signal processing for changing a position or size of the object in the image and controls the position or size of the projection video on the projection surface. In a case where the position or size of the object is to be changed by the video signal processing, when a resolution of the projection video of the changed object is less than a predetermined value, the controller controls the projection unit to decrease the angle of view so that the resolution of the projection video is equal to or greater than the predetermined value, and the controller sets the size of the object in the image by the video signal processing.

Abstract: A projection device according to the present disclosure includes a sensor unit (for example, a camera), a detection unit, a controller and a projection unit. The sensor unit detects an object. The detection unit detects a moving object (for example, a person), a first object, and a second object based on a signal output from the sensor unit. The controller generates a projection image such that a first image corresponding to the first object is projected on a first projection region and a second image corresponding to the second object is projected on a second projection region. In this case, the first image is determined based on a position of the moving object, and the second image is determined without depending on a position of the moving object. The projection unit projects the projection image.

Abstract: The projection apparatus includes a projector, a detector, and a controller. The projector projects a projection image on a predetermined projection surface. The detector detects an object on the predetermined projection surface. The controller controls the projection image. The controller specifies a predetermined target object out of the object on the basis of the detection result of the detector. The controller specifies a free space, on which the object is not detected, on the predetermined projection surface on the basis of the detection result of the detector. The controller causes the projector to project content concerning the predetermined target object within a range of the free space by controlling the projection image including the content.

Abstract: A user interface device for detecting an operation, by a finger of a user, on an operation member presented on a projection surface includes a distance detector for detecting a distance to the projection surface, and a distance to the finger, and a controller for detecting the operation based on the distances detected by the distance detector. When presence of the finger between the projection surface and the distance detector is determined, the controller calculates a normal vector of the projection surface based on distances from the distance detector to positions of at least three points on a surface of the projection surface and a distance from the distance detector to the finger, and detects, based on the normal vector, presence or absence of an operation on the operation member.

Abstract: The present disclosure can provide a projector device which includes: a distance sensor which measures a distance to a facing object, a detector which detects a specific target object and a projection plane which is in contact with the target object, based on distance information output from the distance sensor, a projection region determination unit which specifies a contact portion at which the target object and the projection plane are in contact, and determines a region on which a video image which is associated with the target object can be projected, in the projection plane based on the specified contact portion, and a projector which projects the video image to the region, and which can reliably project video images in a region having an intended positional relationship with a specific object.

Abstract: A projector system includes an image acquiring unit configured to temporally and continuously capture an image of a region including the projection plane to generate image information, and a controller configured to calculate distance information as information on distance to the projection plane based on the image information generated by the image acquiring unit and performs predetermined control by using the calculated distance information, and updates the distance information used for the predetermined control at predetermined timing. Regarding update of the distance information, the controller calculates information on movement of an object included in the image information. When determining that the object is not moving, the controller updates the currently set distance information with newly acquired distance information, while when determining that the object is moving, the controller maintains the currently set distance information as it is without updating the currently set distance information.
