Games to Improve the Internet
I read an article about Luis von Ahn, a Computer Science professor at Carnegie Mellon University who just won a MacArthur Fellowship.
Dr. von Ahn is credited with inventing a new field in computer science known as "human computation," which uses novel techniques, including games, to harness computational abilities of humans to solve large-scale problems computers cannot yet solve.
His games include the ESP Game licensed by Google, and his new game is Phetch. The outcomes of these games are used to produce phrases to label images and to describe them for visually impaired Internet surfers.
