Legion

Legion is a system that enables real-time crowd control of existing user interfaces. Users simply enter a natural language description of the task they want performed and select a region of their desktop to control. Legion manages workers by introducing a crowd agent model that abstracts away the set of workers and makes the crowd function as a single, more reliable, worker.

Legion:Scribe

Legion:Scribe is a system that provides high-quality real-time captions on-demand to users' mobile devices by using the input of multiple non-expert workers. Scribe can generate captions that are cheaper and more readily available than professional stenographers, and more accurate than automatic speech recognition.

Chorus

Chorus provides a two-way conversational interface with the crowd, which can enable robust personal assistants that are powered by the crowd. Prior systems have allowed one-directional natural language interfaces for issuing requests to the crowd, but Chorus is the first work to allow robust dialogue with multiple workers, as if they were a single individual who is aware of the shared conversational history and context.
