Successful User Interfaces for RADAR

We are designing, implementing, and testing the user interface for RADAR (Reflective Agents with Distributed Adaptive Reasoning), which is a large multi-agent system that uses learning to help office workers cope with email overload and to complete routine tasks more efficiently. RADAR provides a mixed-initiative user interface in which artificial intelligence helps users perform the tasks that arrive in email messages. A large-scale user test of RADAR demonstrated the effectiveness of its user interface and AI.
