H1TA-based tracking of pilot actions in the cockpit

Abstract

This work presents a computational goal-oriented task model based on Hierarchical Task Analysis (HTA) able to support accurate tracking of pilot actions and current goals in a controlled environment. Formal semantics are proposed to capture the expressiveness of pen and paper HTA using a computational approach based on open petri nets. Finally, a case study involving professional airline pilots is conducted to demonstrate the resulting tracking system with realistic data.
