Abstract

A visual characteristic on a physical surface in the physical space is determined from an image of a physical space, with the physical surface including a first area inside the visual characteristic and a second area outside of the visual characteristic. A first region of virtual space that corresponds to the first area and a second region of virtual space that corresponds to the second area is determined based at least in part on the visual characteristic. Information that includes a position and orientation of a digital object relative to the first region and the second region in the virtual space is determined based at least in part on the visual characteristic. The digital object is rendered at a position and orientation in the virtual space in accordance with the information.

Claims22

Dependent claims

A system, comprising:

an optical see-through display device;
an image capture device;
and
memory including executable instructions that, if executed by one or more processors, cause the system to:
obtain, via the image capture device, an image of a first physical space;
detect, within the image, a visual characteristic in the first physical space associated with a physical mat, the physical mat being a representation of a second physical space separate from the first physical space, at least a portion of the visual characteristic emitting or reflecting light with a wavelength outside a range of 390 nanometers to 700 nanometers, the image capture device being capable of capturing the at least a portion of the visual characteristic;
determine, based at least in part on the visual characteristic, first information in a virtual space that corresponds to the physical mat;
obtain second information, the second information including a position and orientation of a physical object located in the second physical space;
determine, based at least in part on the first information and the second information, third information that includes a position and orientation in the virtual space corresponding to the position and orientation of the physical object in the second physical space;
and
render, via the optical see-through display device, a digital object representing the physical object, the digital object at least partially occluding a view of the physical mat at a position and orientation in accordance with the third information.

8 more elements

A non-transitory computer-readable storage medium having stored thereon executable instructions that, if executed by one or more processors of a computer system, cause the computer system to at least:

obtain, via an image capture device, an image of a physical space;
identify a position and orientation of a physical surface in the physical space, the physical surface comprising a first area and a second area;
determine a virtual space corresponding to a volume in the physical space that is proximate to the physical surface, the virtual space comprising a first region corresponding to the first area and a second region corresponding to the second area;
determine, based at least in part on a visual characteristic of the physical surface, information that includes a position and orientation relative to the first region and the second region in the virtual space, the visual characteristic emitting or reflecting light with a wavelength outside a range of 390 nanometers to 700 nanometers, the image capture device being capable of capturing the at least a portion of a visual characteristic;
and
render a digital object in a display at the position and orientation in the virtual space to overlay a view of the physical space.
