The projection done in the CyberTable relies on the knowledge of where the viewers head is. If the CyberTable knows the location and orientation of the user's head, it can use this information to draw the projected world in such away that the objects appear to be 3D to the user.
Julian Beever's pavement drawings are a good example of this concept.
Since the artist knows where the viewer's head is, he is able to create his image in such a way that the world "pops out" of the sidewalk as if it were 3D. Viewing the image from a different angle shows the distortion in the image.
