Abstract
A control unit of a display control device performs size adjustment processing of gradually increasing a size of a virtual object maintained at a predetermined real space position in response to approach of a vehicle to the predetermined real space position until the size becomes a second size from a first size, and performs adjustment such that, in at least a part of a period of the size adjustment processing, when the virtual object is assumed to be a real object existing in a real space, a size change rate of the virtual object with respect to a perceptual distance is smaller than a size change rate of the real object.
Claims9
A display control device installed in a vehicle, comprising:
- a control unit that executes display control when a virtual object is displayed such that a viewer riding in the vehicle can visually recognize the virtual object, wherein
- the control unit displays the virtual object having a first size such that the viewer perceives the virtual object as if the virtual object existed at a predetermined real space position in front of the vehicle,
- the control unit performs size adjustment processing of gradually increasing a size of the virtual object maintained at the predetermined real space position in response to approach of the vehicle to the predetermined real space position until the size of the virtual object becomes a second size, and,
- when a distance from a viewpoint position of the viewer to the predetermined real space position is referred to as a perceptual distance, during the size adjustment processing, the control unit performs adjustment such that, in at least a part of a period in which the size of the virtual object becomes the second size from the first size, when the virtual object is assumed to be a real object existing in a real space, a size change rate of the virtual object with respect to the perceptual distance is smaller than a size change rate of the real object.
A display control method for displaying a virtual object having a first size such that a viewer riding in a vehicle perceives the virtual object as if the virtual object existed at a predetermined real space position in front of the vehicle, comprising:
- a step of performing size adjustment processing of gradually increasing a size of the virtual object maintained at the predetermined real space position in response to approach of the vehicle to the predetermined real space position until the size of the virtual object becomes a second size;
- and,
- when a distance from a viewpoint position of the viewer to the predetermined real space position is referred to as a perceptual distance, during the size adjustment processing, a step of performing adjustment such that, in at least a part of a period in which the size of the virtual object becomes the second size from the first size, when the virtual object is assumed to be a real object existing in a real space, a size change rate of the virtual object with respect to the perceptual distance is smaller than a size change rate of the real object.
