'Augment' Reality with Contact Lenses

Today, a handful of soldiers with advanced gear can see a few digital maps, through helmet-mounted monocles. Some pilots can get data about their world, on heads-up displays. But one day, troops could see an info-"augmented" reality all around them, with contact lenses that provide "first-person shooter-type video game" environments to those that wear them. At least, that's the idea behind the latest project from DARPA, the Pentagon's blue sky science and technology division. The agency's Information Processing Techniques Office announced recently that it's looking for information on "the creation of micro- and nano-scale display technologies for the purpose of creating displays that could be worn as transparent contact lenses." And not in some far-off future. But in "three to five years."
