Eppur la Torre non si muove di un millimetro.

E l'aereo non rallenta, non si rompe né deforma, e non varia la sua traiettoria finché non è tutto bello dentro.

FlatWorld uses Hollywood set construction techniques along with large rear projection screens, to provide a cost effective, scalable, configurable training and simulation environment. Real objects, like door frames and free standing window frames, are placed in front of rear projection screens that are driven by projectors to give the illusion of brick or plaster walls. When the user opens the door or window, the computer simulation causes virtual helicopters or adversaries to appear in the opening. This “mixed reality” environment is augmented with 3D sound and makes for quite an impressive demonstration.

“Can we use this technology for physics-based simulations?” the Director asked. “Sure we can!” blurted the Computer Scientist, without realizing the ramifications of those three words, as usual! Without hesitating to continue digging the hole in which he had stepped, he added, “We could add to this and make something available nowhere else.” His fate was sealed; exactly how does one use mixed reality for scientific visualization? How does one add real objects to virtual space without seeming contrived? Windows and doors are hardly applicable to scientific data. Besides, as soon as one puts real objects in front of a stereoscopic projection, the light is blocked, defeating the 3D illusion.

Professor John Henry Pepper, it would seem, provided the answer over a century ago. By placing the virtual objects “in front of” real objects (not possible with traditional screen projection), an Augmented Virtuality experience is made possible. By adding a traditional rear projection screen behind the real object, one creates a “Reality Sandwich” where virtual objects can be both in front and behind real objects and people.


(What’s All This Reality Sandwich Stuff, Anyhow?)
