Abstract
A virtual reality (VR) head-mounted display (HMD), a computer-implemented method, and a VR tracking system are described. Generally, a VR HMD includes an inertial measurement unit (IMU) and an optical sensor. When a second VR HMD is located in a same physical environment, the VR HMD can be operated to track a motion of the second VR HMD in the physical environment. For example, image data captured by the VR HMD in addition to inertial data of both VR HMDs are used to determine a three dimensional (3D) physical position of the second VR HMD and to track the 3D physical position over time. Three degrees of freedom (DOF) or six DOF for the motion are derived from the tracking.

A computer-implemented method comprising:
- accessing, by a computer system, position data of a first virtual reality head-mounted display, the position data generated based on image data of a physical environment that comprises the first virtual reality head-mounted display, the image data generated by an optical sensor of a second virtual reality head-mounted display;
- determining, by the computer system, a position of the first virtual reality head-mounted display in the physical environment based on the position data;
- and
- causing, by the computer system, a presentation of virtual reality content at the first virtual reality head-mounted display based on the position in the physical environment.
A computer-implemented method comprising:
- accessing, by a computer system, position data of a virtual reality head-mounted display that is located in a physical environment, the position data generated based on inertial data and image data, the inertial data indicating a movement in the physical environment of an optical sensor that is remote from the virtual reality head-mounted display, the image data generated by the optical sensor and corresponding to an image of the virtual reality-head mounted display in the physical environment;
- determining, by the computer system, a position of the virtual reality head-mounted display in the physical environment based on the position data;
- and
- causing, by the computer system, a presentation of virtual reality content at the virtual reality head-mounted display based on the position in the physical environment.
A computer-implemented method comprising:
- determining, by a computer system, a first position of a first virtual reality head-mounted display in a physical environment, the first position determined based on second position data generated based on a second optical sensor of a second virtual reality head-mounted display;
- determining, by the computer system, a second position of the second virtual reality head-mounted display in the physical environment, the second position determined based on first position data generated based on a first optical sensor of the first virtual reality head-mounted display;
- and
- causing, by the computer system, presentations of virtual reality content at the first virtual reality head-mounted display and the second virtual reality head-mounted display based on the first position and the second position in the physical environment.
