Night operations under various military circumstances are characterized by extreme cognitive challenges. Poor illumination condition is the pivotal factor presenting the targets in the form of faint stimulus. Therefore, visual workload increases many fold in identifying the targets. However, to date, there is a dearth of empirical evidence based on objective approaches. Studies conducted in dark simulation room exploring the combined effects of passive night vision system (PNVS), illumination conditions, and distances, simultaneously recording the eye movements. Changes in pupil diameter considered as key parameter in concluding the results. İt is observed that irrespective of independent experimental conditions, the values remain very high, ranging from 6 to 8 mm in diameter. A dark exposed pupil remains dilated for long duration, indicating increased mental workload and decreased visual conspicuity.

摘要

Night operations under various military circumstances are characterized by extreme cognitive challenges. Poor illumination condition is the pivotal factor presenting the targets in the form of faint stimulus. Therefore, visual workload increases many fold in identifying the targets. However, to date, there is a dearth of empirical evidence based on objective approaches. Studies conducted in dark simulation room exploring the combined effects of passive night vision system (PNVS), illumination conditions, and distances, simultaneously recording the eye movements. Changes in pupil diameter considered as key parameter in concluding the results. İt is observed that irrespective of independent experimental conditions, the values remain very high, ranging from 6 to 8 mm in diameter. A dark exposed pupil remains dilated for long duration, indicating increased mental workload and decreased visual conspicuity. Although, the use of PNVS facilitates the identification, but not with the precise details. Thus, cognitive load increases, which may impact the decision-making process.
