 The solution aimed at by Phetch is to label the images external to the web page rather than depending upon the web page author to create proper alt text for each image.Rather than paying people to do the mundane task of labeling images, Phetch aims to create a fun game that produces such descriptions as a side effect of having fun.Phetch was created by Luis von Ahn and Shiry Ginosar of Carnegie Mellon University following the pattern set by the earlier ESP game.
