Delegation in LoA3 Space

We propose a framework and testbed for structured examination of possible delegation approaches, using a three-dimensional model of delegation characteristics: authority, abstraction, and aggregation. The testbed uses Playbook(R), a sophisticated tool for commanding automation in multiple regions of this delegation space. The ability to exert experimental control over various possible delegation approaches to obtain direct evidence of the costs and benefits of an approach will be a vast improvement over ad-hoc design techniques in use today. We propose a range of metrics to assess the effects of a given delegation approach on common human-automation system issues, such as over- and under-reliance, out-of-the-loop performance, loss of situation awareness and inappropriate workload. Our Phase 1 model has been enriched through the addition of a domain mapping from context characteristics to the LoA3 space.
