How does the system cope with moving observers, or the fact that the
position of the observer is not known at any one time? How about
multiple observers. Using a three dimensional projection onto a two
dimensional screen means that the image is only correct from one
particular angle (and maybe only one particular point?). It will be
interesting to see how you can guarantee that your transmissive
display will match the contrast, brightness and colour balance of the
of the surrounding environment, and also how you intend to overcome
the optical distortion introduced by the video camera in the first
place.

Would it not be easier to simply hide the object from view, or
camoflauge it using traditional techniques?

Cheers,

Robin
