Abstract
Human users dealing with multiple objectives in a complex environment (e.g., military planners or emergency response operators) are subject to a high level of cognitive workload. When this load becomes an overload, it can severely impair the quality of the plans created. To address these issues, intelligent assistant systems have been rigorously studied in both the artificial intelligence (AI) and the intelligent systems research communities. This chapter discusses proactive assistant systems, which predict future user activities that can be facilitated by the assistant. We focus on problems in which a user is solving a complex problem with uncertainty, and thus on plan-recognition algorithms suitable for the target problem domain. Specifically, we discuss a generative model of plan recognition that represents user activities as an integrated planning and execution problem. We describe a proactive assistant agent architecture and its applications in practical problems including emergency response and military peacekeeping operations.
