kingpin technology, for walking

There is some ideas on using walking with VR, so I just read somebody say to use ball bearings and I thought up some random way to use that idea and decided to start a thread about that.
A magnet can work through a thin piece of plastic on metal, so the magnet is on one side of the plastic and not touching the metal and the metal is on the other side sticking to the magnet but not touching the magnet.
My idea is to use a bunch of magnets clump a bunch of ball bearings together at the bottom of a tub/bucket. The bucket shape holds a bunch of very tiny ball bearings.
A shoe has magnets that attracts ball bearings too, so the tub has magnets and the shoes have magnets and ball bearings are inbetween the tub magnets and shoe magnets.
The ball bearings touch the magnets on the shoes but not the magnets on the tub, the magnets on the tub acts through metal material that serves to generalize the area the magnets clump too.
When the ball bearings go one way it means the tub is acting, when the ball bearing go the other way it means the shoes are acting.
When the person stands still the magnets in the tub hold onto the magnets on the shoes so the person can stand without falling.
Because the tub holds the magnets the tub is a static motion, or still. The shoes move the magnets dynamically or in contrast with how the magnets in the tub hold them, the shoes disturb the wy the tub holds the magnets.
As the shoes disturb the way the tub holds the magnets this is read by a sensor that differentiates the tub motion from the shoe motion.
If a camera on the treadmill looks at the ball bearings and finds the dynamic vs static motion, it can ID bent knees too, which would allow for crouching to be in the VR.
Then all you would need, not knee-d, is a tub with a metal wall separating the magnets in the tub from ball bearings.
A pair of shoes with magnets that attract the ball bearings in the tub.
A camera to separate the dynamic motion of the ball bearing from the static motion.
And a program to read the camera results and feed this into the VR program as a child of where the head is looking, so the head tracking would be the parent and the walking the child, so when the person walks forward they walk to where the face is pointing currently.
The shoes would be a regular shoe, any brand or type, but the bottom of the shoe is a strap on plate that is metal, and inside the plate is magnets. The entire plate is magnetic though because the magnets inside the plate magnetise the entire plate.
There would be no mechanical parts inside the tub just magnets and a metal wall.
What do you think? Did somebody already make this somewhere on kickstarter maybe?
edit,
I looked around and saw viiwok uses this design too, so it's already being made. I have included the viiwok name in the thread title because of this.
