“…Toet [35] demonstrated that the energy contrast and structural dissimilarity between targets and distractors affect the perceptual and conceptual search performance respectively. Hence, VC can be adopted to measure salient targets [16,27,36,37]. VC is defined as background images that confuse and distract observers.…”

Navigated inspection seeks to improve hazard identification (HI) accuracy. With a tight inspection schedule, HI also requires efficiency. However, lacking quantification of HI efficiency, navigated inspection strategies cannot be comprehensively assessed. This work aims to determine inspection efficiency in navigated safety inspection, controlling for HI accuracy. Based on a cognitive method of the random search model (RSM), an experiment was conducted to observe the HI efficiency in navigation, for a variety of visual clutter (VC) scenarios, while using eye-tracking devices to record the search process and analyze the search performance. The results show that the RSM is an appropriate instrument, and VC serves as a hazard classifier for navigation inspection in improving inspection efficiency. This suggests a new and effective solution for addressing the low accuracy and efficiency of manual inspection through navigated inspection involving VC and the RSM. It also provides insights into the inspectors' safety inspection ability.

“…Additionally, depending on the anomaly, experts employ a 138 mixture of focal and diffusive, or ambient, gaze strategies [44][45][46]; however, they are 139 more accurate at determining anomalies than novices and intermediates. 140 Beyond gaze strategies based on fixations and saccades, other forms of eye 141 movements that have been used to measure aspects of cognition during visual search 142 include their speed and direction [5], microsaccades [47], pupil diameter oscillation [48], 143 and measures related to pupil diameter itself [49]. Generally, most of these measures 144 concentrating on estimation of cognitive load have produced metrics sensitive to the 145 presence or absence of cognitive load.…”

Expert behavior is characterized by rapid information processing abilities, dependent on more structured schemata in long-term memory designated for their domain-specific tasks. From this understanding, expertise can effectively reduce cognitive load on a domain-specific task. However, certain tasks could still evoke different gradations of load even for an expert, e.g., when having to detect subtle anomalies in dental radiographs. Our aim was to measure pupil diameter response to anomalies of varying levels of difficulty in expert and student dentists' visual examination of panoramic radiographs. We found that students' pupil diameter dilated significantly from baseline compared to experts, but anomaly difficulty had no effect on pupillary response. In contrast, experts' pupil diameter responded to varying levels of anomaly difficulty, where more difficult anomalies evoked greater pupil dilation from baseline. Experts thus showed proportional pupillary response indicative of increasing cognitive load with increasingly difficult anomalies, whereas students showed pupillary response indicative of higher cognitive load for all anomalies when compared to experts.
