Re: your thoughts on future gaming
Holograms are actually a thing we've got now.... although crude compared to that of sci-fi.
Now and then I like to watch the Discovery channel and there was something about some fair in Japan (where else?) where some hot Japanese chick wore some gloves and was moving objects around on a table. Guess what? Holograms! The items were holograms, of sorts, and detectors and sensors in the gloves made it possible to "move" them around. For example she pushed one box around by poking it...
There was also a funky little room you could enter with lots and lots of cameras covering all angles of your body that took your picture all at once and then projecting a hologram of a miniature image of you, not unlike that in sci-fi.
