SYSTEM FOR DETECTING SIX DEGREES OF FREEDOM OF MOVEMENT BY TRACKING OPTICAL FLOW OF BACKSCATTERED LASER SPECKLE PATTERNS

摘要

The augmented reality headgear includes transparent displays that allow a user to simultaneously view the real world and virtual content positioned in the real world, generated when the coherent light and at least one source of coherent light collides with environmental surfaces and at least one sensor array for detecting the speckle patterns at a series of times. Circuitry is provided for detecting shifts in the speckle pattern, determining the motion that caused the shift in the speckle pattern, and adjusting the display of virtual objects displayed by the augmented reality headgear to compensate for the motion.
