Not looking at how the eyes are recorded, I will start on how the eyes see something that can be recorded.

If you have a square grid, and the grid is able to light up.

First you need to measure how far the eye can see, up, down, left, right, and get the grid to match these extremes the eye can see with the size of the grid.
So when the eye looks as far up as it can it sees the top of the grid, as low as it can it sees the bottom of the grid, and as far side to side as it can it sees the farthest left and right of the grid.

Second, the eye sees the grid light up. And here the eye position is matched to a grid.
So the grid lights up, and the eye position that sees the grid light up is recoded, and this is the position of the eye that sees that part of the grid.
So the grid equals a eye position.
This is done for both eyes since some eyes are lazy or deformed etc, this is custom measured per person.

Third, the 3D stereoscopic pair displayed to the person is based on the grid.
The left eye picture is made to be on this part of the grid, and the right eye picture is made to be on this part of the grid, then the eyes should see a stereoscopic picture.

Fourth, the grid lines up to what the eyes see - therefore, the eyes line up to the grid and the grid to 3D. It's synchronicity; (the line goes one way, 3d to grid to eyes), (then it can go the other way, eyes to grid to 3D).

Fifth, the eyes stop moving to focus, and then when the eyes focus the eyes see.
So there is motion then no motion. And when there is no motion what happens is something is visible in 3D.

Also, if you look at your neck motion as you do these eye motions;
- look forward into the distance
- look at a foot in front of you
- look to your side at a distance
- look to your side at a close distance.

Your neck relates the distance your eyes are looking.

1.) your eyes move then stop to see.
2.) your neck relates the distance your looking.

Since we made a grid to show how the eyes can see the grid, and measured the eyes position and matched this to the grid.
Then the neck is used to measure the distance you look, so a grid needs to match the neck to a distance grid.

If there is a grid that can be lit up and lets you see into the distance or close to you as it lights up.
Sort of like seeing the floor tiles light up.
Then they light up and your neck position is matched to the lit grid tile.

Now the neck position matches a grid tile and the eyes match a lit grid. So when the eyes move to a part of the grid the neck moves to a part of the grid, and then the stereoscopic picture can be shown to the eyes of the person.

Sixth, in the kingpin technology, the weight resets the button after the button is depressed.
This resetting of the button can be when the stereoscopic picture is shown to the eyes.
- The eyes move the buttons are pressed in and match a part of the grid for the neck and eyes.
- The eyes stop, the buttons are reset and the eyes see a stereoscopic picture.

Seventh, the way to measure neck motion is to use the difference the dynamic chin motion from the static position on the neck.
So something static is on the neck and the chin shows the difference as it moves around. This difference is visible on the lit grid, as the chin moves, the eyes are looking at a certain spot on the grid.

To measure the eyes you need 4 sensors at the four spots the grid is looked at, to the sides of the eye and the top and bottom of the eye.
Then the grid is lit up and sensor 1 measures the eye is at position x,y, and sensor 2 shows the eye is at position x,y, etc for all four sensors.

The neck sensor shows neck tracking and the four sensors around both eyes shows eye tracking, but they are both used for eye tracking here.
The neck shows the distance being looked at, and the eyes sensors shows the part of the grid the eyes are looking at.
