Real-Time Vision for Human-Computer Interaction 

200Ts Vision of Vision One of my formative childhood experiences was in 1968 stepping into the Uptown Theater on Connecticut Avenue in Washington, DC, one of the few movie theaters nationwide that projected in large-screen cinerama. I was there at the urging of a friend, who said I simply must see the remarkable film whose run had started the previous week. ‘You won’t understand it, ‘ he said, ‘but that doesn’t matter. ‘ All I knew was that the film was about science fiction and had great special efl Pects. So I sat in the front row of the balcony, munched my popcorn, sat back, and experienced what was widely touted as ‘the ultimate trip:’ 2001: A Space Odyssey. My friend was right: I didn’t understand it. . . but in some senses that didn’t matter. (Even today, after seeing the film 40 times, I continue to discover its many subtle secrets. ) I just had the sense that I had experienced a creation of the highest aesthetic order: unique, fresh, awe inspiring. Here was a film so distinctive that the first half hour had no words whatsoever; the last half hour had no words either; and nearly all the words in between were banal and irrelevant to the plot – quips about security through Voiceprint identification, how to make a phonecall from a space station, government pension plans, and so on.
