Abstract:
A system for hand tracking may comprise a head mounted display wearable by a user and a hand tracking camera module attached to the head mounted display and comprising at least one of a pair of stereo cameras or a depth camera. The hand tracking camera module may be configured to capture images of at least one physical hand of the user. The head mounted display may be configured to render a virtual hand resembling the physical hand in a virtual environment for viewing by the user based at least on the images.

Claim (Index 19):
An apparatus for hand tracking, comprising:\n a head mounted display; a hand tracking camera module attached to the head mounted display and comprising at least one of a pair of stereo cameras or a depth camera; a processor; and a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to perform a method, the method comprising:\n (step 14) causing the hand tracking camera module to capture an image of at least one physical hand of a user wearing the head mounted display; \n (step 15) obtaining the image in a current frame and least one of determined skeleton joints or a determined 3D object pose in a previous frame as inputs to execute a Hand and Object Detection algorithm to determine if the physical hand holds an object in the current frame; \n (step 16) in response to determining that the physical hand holds no object:\n executing a 3D Hand Skeleton Joints Recognition algorithm to determine 3D skeleton joints of the physical hand in 26 degrees-of-freedom in the current frame, \n causing the head mounted display to render a virtual hand resembling the physical hand in a virtual environment for viewing by the user based at least on the determined 3D skeleton joints, and \n feedbacking the determined 3D skeleton joints to the Hand And Object Detection algorithm for determining if the physical hand holds any object in a next frame; \n \n (step 17) in response to determining that the physical hand holds an object:\n executing a 3D Hand Skeleton Joints And Robust Object Pose Recognition algorithm to determine 3D skeleton joints of the physical hand in 26 degrees-of-freedom and a 3D object pose of the object in the current frame, \n causing the head mounted display to render a virtual hand resembling the physical hand in a virtual environment for viewing by the user based at least on the determined 3D skeleton joints, and \n feedbacking the determined 3D skeleton joints and the determined 3D object pose to the Hand And Object Detection algorithm for determining if the physical hand holds any object in a next frame; and \n \n (step 18) recursively performing (step 14)-(step 17) for the next frame.
