Can't use Touch with a single camera

Hi,

Is it possible to use Touch with a single camera? When I try to use them (btw, what app or game would you recommend to test them with?) with SteamVR and apps that support Touch (Big screen, for example) the controllers lose tracking and fly away each half a second or so.

So you have touch controller already? You will need at least 2 sensors because you will lose tracking if you use just one.

Yes, not a consumer version, though. I know that it would be much less convenient to use Toch with a single camera even if it works but I have only one at the moment.

I missed that it absolutely requires having 2 cameras. Have you seen that written in some docs or was it communicated by someone from Oculus?

With just one camera on your desk, it's easy to move your hand outside of the tracking area - the camera sensors weren't really designed to track objects that can be moved an arm's length away from the center from nearby. You will probably have a better experience if you move your sensor camera further away (and recalibrate the sensor), so you are in a larger part of its viewing cone.

Touch comes with a second camera.  That's the whole point, so you'll have the required number of cameras to use touch.

If you are facing the sensor then it will track the touch controllers. But as soon as you turn 180 degrees you are no longer facing the camera and will lose tracking due to the controllers been masked. You need 2 sensors so that the controllers can be constantly tracked. There is even talk of 3 sensors been the best setup.

It's supposed to be a minimum of 2 cameras.  The one that came with your rift, and there's one that comes with touch.  A 3rd camera will be available later on.

Take a look at what is packed in with the Touch controllers, it comes with an additional camera.
