Writers may not have seen the hologram coming, but they certainly saw where it could go well before science did. I don't know about you, but I remember the little hologram trinket craze of the late 70s and early 80s. At the time, that seemed to be all we were going to get from holographic technology. Things like
However, in 1983, we were introduced to
Of course, we also had Quantum Leap in the late 80s with its holographic sidekick played by Dean Stockwell. And there was the lesser known (because of not being very successful) show Automan in 1983
But all of that is beside the point, because I want to get to something real. This:
And it was purely fictional in the sense that no one had thought of it before. At least, not like this. Spielberg did something interesting, though. He wanted a movie that looked and felt real, so, instead of just making a bunch of stuff up, in 1999, he invited... well, he invited some experts to help him devise a plausible future reality. The holographic interface he used in the movie was one of the ideas they came up with, and it has since become a reality. Well, maybe not quite to the extent that it's used in the movie, but it's on its way.
In fact, when Microsoft was developing this technology for the Xbox 360, they hired engineers to "create Minority Report inspired user interfaces." I don't know how you can get a more direct link from fiction to reality than that. It's really one of those "Hey, that's cool! Let's make one of those for real!" kind of things.
