Traditional displays and touch surfaces don’t adjust what you see when you walk around them, so aren’t capable of creating true virtual 3D objects such as those shown in the video.
Occulus Rift blocks your view of the room you’re in, so if you were to try walking around a virtual object you’re likely to end up hurting yourself. You also can’t interact directly with and alter the 3D graphics (as shown in the video with the wand and miniatures).
