Hello. This app seems like a great move towards more accessible VR gaming, but as you know, it's biggest limitation seems to be the tracking of the hands/controllers.
I think adding support for playstation move controllers may possibly make it actually viable for gaming and not just testing. Head movement can still be handled by the camera, while controllers can be handled by the more-specialized and accurate moves.
It would be more accessible than a headset as all you'd need are move controllers.
