How to verify if head tracking is working correctly

FAQ » How to verify if head tracking is working correctly

You can verify if tracking is working correctly.
Take look at "Cam Y" value when tracking is on.
For example, I get Cam Y = ~880.0
Then switch mode to "Static Cam" and enter this value.

For example it shows me, that it is "66cm" from screen.
I measure this distance in reality from my eye to screen border.
I get ~60 cm.
