Tracking System for Head Mounted Display

A method for tracking a head mounted display (HMD) used for rendering a virtual reality scene, the HMD including a display screen for rendering the virtual reality scene, the method comprising:

• capturing image data using at least one device integrated on an external surface of the HMD, the image data capturing a real space in which the HMD is located;
• processing the image data to identify at least two points of light projected upon a surface in the real space;
• continuing the capturing and the processing to identify changes in location of the at least two points of light in the captured image data, the changes in location identifying position and pose changes by the HMD in the real space;
• wherein the position and pose changes are configured to automatically control rendering adjustments to the virtual reality scene rendered on the display screen of the HMD, the adjustments including one or both of changes in a view perspective into of the virtual reality scene and rendering of additional content for the virtual reality scene.

A head mounted display (HMD), comprising,

• a housing including a screen for displaying images associated with a virtual reality scene;
• a sensing device integrated on an external surface of the housing;
• and
• a processor for controlling capturing of image data by the sensing device, the image data capturing a real space in which the HMD is located along with at least two points of light detected to be projected by an emitter onto a surface of the real space, the processor is configured to continually transfer the image data to a computing device during position tracking of the HMD in the real space, the processor configured to identify changes in position and position and pose of the HMD based on changes in location of the at least two points of light in the image data, the processor is further configured to receive content for the virtual reality scene to be rendered on the screen based on the identified changes in position and position and pose;
• wherein the changes in position and position and pose cause automatic adjustments to one or both of a view perspective into of the virtual reality scene and rendering of additional content for the virtual reality scene.
