Behavior Design Patterns: Engineering Human Behavior Models

This paper describes new research that attempts to address cost and development time bottlenecks in the implementation of high-fi delity human behavior representations. The proposed solution, behavior design patterns (BDPs), is an extension of design patterns in traditional software engineering. A crucial challenge for BDPs, and the fundamental limitation of existing design patterns, is capturing the unique computational properties of human behavior models (HBMs), which require parallel, goal-oriented execution to achieve autonomy, fl exibility and adaptation in task performance. We demonstrate example patterns extracted from an existing HBM, TacAir-Soar, and describe how they can be applied in other HBMs. Although the results are preliminary, one advantage to the proposed approach is the development of solution catalogs, which can be used to improve development today, even while more powerful development tools are being designed and constructed.
