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 4):
The system of  claim 1 , wherein:\n to render the virtual hand resembling the physical hand in the virtual environment for viewing by the user based at least on the images, the system comprises a processor and a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to perform a visual tracking method, the method comprising:\n (step 1) obtaining an 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 2) 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 rendering the virtual hand 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 3) 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 rendering the virtual hand 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 4) recursively performing (step 1)-(step 3) for the next frame.
