Intelligent systems are becoming more and more of a reality but with the exception of very special purpose systems, completely autonomous systems are not yet the norm. In reality, we need to have humans who monitor the systems, intervening when necessary. As systems increase in intelligence, the goal for human-in-the-loop activities should not be to eliminate the human, but rather to create a human-system partnership with greater capabilities than the individual components. We currently view intelligent systems and the operators or supervisors of these systems as separate components and conduct evaluations in the same vein. For intelligent systems to become more useful and acceptable, we need to consider the system as a synergistic composition of software behaviors, possibly embedded in a physical component such as a robot, and the human interacting with this virtual or physical component. Our objective is to design this team interaction in such a way that the intelligence of the team is greater than the intelligence of any one of the parts.
