Inspection filtering & eye tracking

The aim is to provide practical insights into two key areas:

• Improving the detection rates (hit rates) of illicit items.
• The objective determination of shift lengths for imaging posts to prevent cognitive fatigue.
• Understanding the factors that influence activity in order to identify the most effective visual strategies.

Under the auspices of our research laboratory CRIHS (Centre for Human-System Research and Innovation), we have implemented a methodology structured in three phases:

1. Inductive Phase : Literature review, definition of data collection hypotheses and ensuring that stakeholders are in agreement with the experimental protocols.

2. Deductive Phase : In vivo data collection using portable eye-tracking devices from 25 participants divided between conventional and multiplexed workstations (Cabin and Hold).

3. Cross-tabulation : Correlation between oculometric metrics and actual operational performance to validate a model of optimal performance.

The study provided objective performance indicators and decision-making tools:

• Modelling optimal performance based on the operators’ moments of attention and inattention.
• Comparison: expert vs novice to refine initial and continuing training processes.
• Ergonomic recommendations on the development of work interfaces and the management of shift lengths to reduce monotony.

Unique expertise combining neuroscience and business

Human Design Group has brought together a high-calibre multidisciplinary team:

• Dual expertise : Proficiency in neuroscientific tools (Human Data Science) and in-depth knowledge of airport security roles gained whilst working at the DGAC.
• Trusted third party: Ability to assess performance indicators objectively and impartially on behalf of ADP.
• Tangible assets : Use of state-of-the-art sensors (portable and remote eye-tracking) suited to complex environments.
