Lets Gamestorm some out of the box ideas..
we can have 8 Switches connected = 16 controllers = 16 point field calibration.
We could use a setup to actually create a augmented space of sorts in a room...
Using mult Switch Consoles setup at different verts points in a room forming a invisible circle cage.
Using the controllers to scan the area from static positions as well.
also note, using max amount of hardware because.. ya know.. why not
have one unit docked, call it PRIME
Now we have a virtual space to play in an hexadecagon of sorts that can read your movements hands free.
That at least sets up a room.. im assuming that the ir readers pick up at least 12 feet away. (two full male adult lengths apart)
we could even elevate the angles of the controllers to capture a more realized 3d image of the player and surrounding.
EDIT::ONE SWITCH CONSOLE CAN SUPPORT UP TO 8 JOYCONS. so I am guessing its either or. for each system you use, takes up some slots. but you can connect 8 switches in a lan party.. offering 16 controller configs. Is that the max limit? or is it 32 or 64?
