Not a game
Using Open Cv and a small database of devices(a cell phone, a car, a TV, a computer etc) to make a 3d real time blueprint overlay to start.

I need someone who is familiar with open cv, I can write the object Res and orientation change but need help with the 3d object database.

By creating a blueprint and having a device broadcast its location and orientation via bluetooth the same result could be achieved, by overlaying the blieprint in realtime by getting its local position offset and angle. Eventually this tech could allow On Board diagnostic programs to highlight broken areas or you could teach with it.
