Augmented + head tracking reality using camera and sensors

There is one camera
there is 6 sensors the camera can detect;
3 sensors on the person, 3 sensors on the environment.
One of the sensors on the person is on the chest bone that doesn't move when the person moves.
Two sensors are one head, I don't know if the head is the best place so some calibration would have to be done to know for sure, but it's a spot on the body that moves unlike the chest bone that's still.
These sensors on the person are used for triangulation.
The sensors on the body relate to the sensors in the environment.
If the environment has a flat surface like a table, the chest sensor is shown on the environment sensors as a axis the other two sensors tilt around like a seesaw.
Hold out your hand in front of you so you see the side of your hand, with your thumb facing you and the pinky is facing outwards.
Now swing your elbow left and right under your hand so it swings like a pendulum.
While your elbow is swinging hold your hand still so if see your hand is against a straight line in the background it stays on the line.
This is the basic idea.
The line in the background is the environment sensors.
The hand still is the chest sensor, the elbow swinging is the sensors on the head or arms.
e.g. As the person is still the see a virtual 3d triangle on a table surface.
As they move the triangle stays on the surface of the table.
The triangle stays flat on the table and doesn't move because like the hand held still while the elbow swings, the triangle is being corrected in SW to appear still while the person moves.
