Abstract
At a first time point, a first light capturing device at a first spatial location in a three-dimensional (3D) space captures first light rays from light sources located at designated spatial locations on a viewer device in the 3D space. At the first time point, a second light capturing device at a second spatial location in the 3D space captures second light rays from the light sources located at the designated spatial locations on the viewer device in the 3D space. Based on the first light rays captured by the first light capturing device and the second light rays captured by the second light capturing device, at least one of a spatial position and a spatial direction, at the first time point, of the viewer device is determined.
Claims23
A method, comprising:
- capturing, at a first time point by a first light capturing device at a first spatial location in a three-dimensional (3D) space, first light rays from a plurality of light sources located at a plurality of designated spatial locations on a viewer device in the 3D space;
- capturing, at the first time point by a second light capturing device at a second spatial location in the 3D space, second light rays from the plurality of light sources located at the plurality of designated spatial locations on the viewer device in the 3D space;
- based on the first light rays captured by the first light capturing device and the second light rays captured by the second light capturing device, determining at least one of a spatial position and a spatial direction, at the first time point, of the viewer device.
A device tracker, comprising:
- a first light capturing device, at a first spatial location in a three-dimensional (3D) space, that captures, at a first time point, first light rays from a plurality of light sources located at a plurality of designated spatial locations on a viewer device in the 3D space;
- a second light capturing device, at a second spatial location in the 3D space, that captures, at the first time point, second light rays from the plurality of light sources located at the plurality of designated spatial locations on the viewer device in the 3D space;
- wherein the device tracker determines at least one of a spatial position and a spatial direction, at the first time point, of the viewer device based on the first light rays captured by the first light capturing device and the second light rays captured by the second light capturing device.
