Multi-user interactive 3D gaming experiences, no headset required.
I can still remember the first time I saw Star Wars: A New Hope; the genuine awe of seeing Princess Leiah send a holographic message to Obi-Wan Kenobi and wondering, “WOW! When will we be able to send messages like that!?”
Even more interesting was the scene in which Chewbacca and R2-D2 go head-to-head in a round of Dejarik, a.k.a. “Holochess.” Watching the massive Wookie smack the table in frustration as his virtual set pieces were devoured by other holographic monsters is something I’ll never forget.
Thanks to the efforts
