According to that blog post, the range limits on the sensors are thus:
Doing the math, if you're working with a 12ftx12ft space, mounting at 8ft and angling down at 45 degrees, each sensor's FOV will cover more than half the room but end before it reaches the opposite corner.
So, in theory, tracking should be solid in the middle of the room but you might see some wonkiess near the floor at the corners.
It's hard to give a definite answer based solely on theory though, so you might want to experiment with your sensors' placement using
DeskScene or
Guardian Boundary Editor before you mount them.
Both of those allow you to visualize the overlap between your sensor volumes and get a better idea of your room coverage, though it does involve re-running the oculus room setup every time you move them.
Essentially you want to make sure there's as much overlap as possible between the three sensors' FOV so they can cover eachother's blind spots and form an 'optimal tracking volume'.
To give a visual example, here's a screenshot from Guardian Boundary Editor. I've been running my 3-sensor setup in an 8ftx8ft space with an effective play area of 6ftx6ft for safety's sake:
Note the blue heatmap-looking background; that represents the sensors' cumulative FOV. More blue = more coverage, so I've positioned the play area to cover as much of the optimal space as possible without getting too close to a wall.
Going counterclockwise from the top left, the sensors are:
- 6ft high / USB3
- 6ft high / USB2
- 7ft high / USB3
They're all angled ~45 degrees down toward the center, and I have the opposing ones running on USB3 so there will always be one high-bandwidth sensor with a good view.
The side one I've left on USB2 due to lack of bandwidth, so it's mostly there as a corrective assist for when one of the other sensors can't see a controller. Tracking has been flawless so far.
Whew, accidental essay post. I hope that helps!
