Visual search for people wearing protective clothing in a forestial environment – Differences between gaze and behavior

Sixteen observers searched forest images containing 22 models. Reflective vests reduced misses more than reflective hatbands; eye-tracking showed searchers often looked from a vest to the face before recognising a person.

Why it matters: It reinforces that visibility aids are part of field safety, but also that detection and recognition are separate. A technician can fixate on high-visibility clothing yet still need confirmation through shape, face, movement or context.

Limitations and transferability: Static images, 16 observers and protective-clothing conditions—not live ground searches for a concealed casualty or clue. Applicable as supporting evidence for visual-search practice and team visibility, not for calculating POD.

Training influence: Include subjects with high- and low-contrast clothing in woodland exercises. Ask searchers to state what they saw, what made them classify it as human, and when a second viewpoint/confirmation is appropriate.

SAR training sections: Visual search; clue awareness; field safety; ground-search tactics; searcher spacing and coverage.
