As of this week, you can buy your own little piece of “Minority Report” and “Iron Man”: controlling your computer by making hand motions in the air.
So when will we really get those technologies? Probably on the 11th of “Don’t hold your breath.” We know about the flying cars (thank you, “Blade Runner”), holograms (thank you, “Star Trek”) and robot butlers (thank you, “Jetsons”). By now, we all know what the future will be like movies and TV shows have described it in detail.
