The Japanese Eroge game devs were already using this thing to add 6DoF room-scale tracking to the OculusDK2 back in the days, and they also added hand tracking(so you can grab the girl's boobs) via LeapMotion.
They did a free demo session in a public VR conference, where you could play Custom Maid3D in 6DoF-VR.(and this was even before HTC Vive was announced)
so never underestimate the Hentai Nips...
and yes, that was my first VR experience @_@
