Current VR might not be as convincing as the Matrix, but this Google Tango app lets you peer into the real world as if you were Neo himself.
The Tango Martix Scanner from VR and AR developer Null Real uses the special cameras fitted to Tango-ready Android phones to turn the walls, floors and ceilings of the environment around you into the virtual data streams that Keanu Reeves sees towards the end of the legendary 1999 sci-fi flick. You can walk around the room and peer into the camera as if you were really in the Martix. Pretty cool, huh?
Null Real is working on some other interesting projects too, like position tracking for mobile-based VR with no external sensors.
