Whereas VR goggles immerse a user in a computer-generated environment, AR uses semi-transparent goggles, which overlay computer-generated graphics onto a user's view of the physical world.
Both the 3D data (MPO format) and the JPEG data are saved. 3D Photo can be used in Auto (after the first shot is complete, the second shot will automatically be taken once the camera is moved to match the target) and Manual (after the first shot is complete, the user takes the second shot after matching the semi-transparent layers).
