Umati is a crowdsourcing vending machine. Instead of inserting money into the machine to pay for snacks, users complete crowdsourcing tasks on an integrated touchscreen. Umati allows us to target specific communities who don't traditionally participate in crowd work with tasks suited to their skills and knowledge. We also target these communities with rewards that suit them and in locations where they have cognitive surplus. We deployed Umati at UC Berkeley and found we were able to cheaply crowdsource the grading of computer science exams, a task that cannot be accomplished on Amazon's Mechanical Turk.
