Google TechTalks July 26, 2006 Tasks like image recognition are trivial for humans, but continue to challenge even the most sophisticated computer programs. This talk introduces a paradigm for utilizing human processing power to solve problems that computers cannot yet solve. Traditional approaches to solving such problems focus on improving software. I advocate a novel approach: constructively channel human brainpower using computer games. For example, the ESP Game, described in this talk, is an enjoyable online game — many people play over 40 hours a week — and when people play, they help label images on the Web with descriptive keywords. These keywords can be used to significantly improve the accuracy of image search. People play the game not because they want to help, but because they enjoy it. I describe other examples of “games with a purpose”: Peekaboom, which helps determine the location of objects in images, and Verbosity, which collects common-sense knowledge. I also explain a general approach for constructing games with a purpose. Here’s some links to the games mentioned, and others that work on the same principles: ESP Peekaboom Google Image Labeler Phetch (multiplayer game) Verbosity (Apparently the server doesn’t work) A few more links: O’Reilly’s short write up on this lecture All in all, a fascinating talk on a trend that I believe is going to be one of the most important any of us will face. As the symbiosis between humans and computers becomes deeper, and at a larger scale, we’re going to see problems that were formerly construed as “hard AI” suddenly broken, not because computers themselves have become intelligent, but because humans and computers have gotten better at working together. We’re only at the early stages of harnessing collective intelligence, and we’re going to see more and more breakthroughs as creative computer […]
