For the past three years, GROUP (Group for Research On Usage and Pragmatics) has been developing the VesselWorld system. In VesselWorld, three participants collaborate on remote workstations to remove barrels of toxic waste from a harbor. Each participant is the captain of a ship, and their joint goal is to remove all of the barrels from the harbor without spilling any toxic waste. Each ship has a geographically limited view of the harbor and some unique capabilities. To safely remove a barrel of waste from the harbor requires varying degrees of coordination between the participants.
