Human Computation

Tasks like image recognition are trivial for humans, but continue to challenge even the most sophisticated computer programs. This talk discusses 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 to perform the tasks that computers cannot yet perform. 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.
