Portable Projectors
"Chances are you can’t remember the last time you hauled a projector out of the attic to look at slides or movies. But, says Ramesh Raskar, you may soon carry one with you everywhere you go. Raskar, a research scientist at Cambridge, MA’s Mitsubishi Electric Research Laboratories, sees tiny projectors as the solution to one of the fundamental problems with our ever shrinking cell phones, PDAs, digital cameras, and other portable devices. The gizmos carry more and more of our data, but they are running out of room to display it to us. Build a tiny projector into each of those devices, though, and the world becomes your display."
"Raskar’s team has developed hardware and software that can project digital images onto whatever surface is handy—the wall, say, or a desktop—and make them look good even if the impromptu screen isn’t nice and smooth. And “once you buy into this notion that people would like to have this kind of an attachment,” he asks, “what will they do beyond just looking at those images?” Raskar envisions projectors as the heart of a whole new way of interacting with the world, and he shared his vision with Technology Review senior editor Rebecca Zacks." -- From "Portable Projectors", by Rebecca Zacks, Technology Review, Dec 2004
