This page provides generic and qualitative information about SaIRA.
What is SaIRA?
I am currently working on the Safe and Interactive Reconfiguration Architecture (SaIRA), a Decision Support System (DSS) for aircraft/spacecraft pilots designed to improve human decision-making performance and accuracy in safety-critical scenarios.
What does it do?
SaIRA helps pilots to make complex, fault management decisions in critical situations, under time-pressure. The system is designed to parallel human cognitive strategies and generate decision support information that allows for reduced decision time and increased accuracy.
How does it do it?
The system uses artificial intelligence algorithms based on the Constraint Programming and Evidential Reasoning paradigms to process sensor signals coming from the aircraft/spacecraft avionics. The information is then used generate structured, “human-friendly” decision support information that allows for rapid and effective decision-making. The strategies to generate the decision support information are based on Naturalistic Decision Making principles.

Is it effective?
SaIRA has been extensively validated through a human-computer interaction campaign of experiments. 13 civil pilots participated to the experiments. Check my publications page for detailed information. The experiments reveal that SaIRA improves pilots' decision accuracy, decision performance, situation awareness and, more generally, their cognitive readiness whilst reducing cognitive workload and frustration under heavy time pressure.
I developed bespoke eye-tracking software to assess the effectiveness of the system. The software is named SaIRA Eye-Tracking System (SETS) - see the images below.
