Patent ID: 11403830

Abstract:
A certain object is enlarged or reduced to generate a visual object in a VR space without significantly changing an apparent quality. A first object in a real space or a virtual reality space is enlarged or reduced to generate a second object that is a visual object in a virtual reality space. Here, a first visual angle that is a visual angle or an estimated visual angle formed by the first object at a real observation position in the real space or a virtual observation position in the virtual reality space is the same or approximately the same as a second visual angle that is a visual angle formed by the second object at the virtual observation position, a second distance that is a distance from the virtual observation position to the second object is longer than a first distance that is a distance or an estimated distance from the real observation position or the virtual observation position to the first object when the second object is obtained by enlarging the first object, and the second distance is shorter than the first distance when the second object is obtained by reducing the first object.
