Methods and systems for determining 6dof location and orientation of head-mounted display and associated user movements

A system for determining a location and an orientation of a display device utilized by a user, the system comprising:

• a communication module configured to receive, from the display device, orientation data, wherein the orientation data is associated with a user-centered coordinate system;
• a depth sensing device configured to obtain one or more depth maps of a scene within which the user is present;
• and
• a computing unit communicatively coupled to the depth sensing device and the communication unit, the computing unit is configured to:
• dynamically determine a location of a user head based at least in part on the one or more depth maps;
• generate location data of the display device based at least in part on the location of a user head;
• and
• combine the orientation data and the location data and generate 6DoF data associated with the display device.

A non-transitory processor-readable medium having instructions stored thereon, which when executed by one or more processors, cause the one or more processors to implement a method for determining a location and an orientation of a display device utilized by a user, the method comprising:

• receiving orientation data from the display device, wherein the orientation data is associated with a user-centered coordinate system;
• receiving one or more depth maps of a scene, where the user is present;
• dynamically determining a location of a user head based at least in part on the one or more depth maps;
• generating location data of the display device based at least in part on the location of the user head;
• and
• combining the orientation data and the location data to generate six-degree of freedom (6DoF) data associated with the display device.
