Google recently made a splash with its QuickDraw experiment, which challenged users to get a machine learning algorithm to guess what they were drawing as quickly as possible, and the company is putting the data it collected from that game to use with the new Google AutoDraw tool. The tool, which is currently set up as an independent website, will immediately process the images that users are drawing and supply them with a set of stock images that it believes the user was trying to draw.
In and of itself, Google AutoDraw is more of a gimmick than a useful tool. Users are usually more inclined to simply play and explore the blank canvas than to actually use the tool for anything practical. Nonetheless, the impressive accuracy that it offers (especially considering the noted lack of artistic expertise from at least one user) could easily translate to more pragmatic software.
