Visual Performance and Marksmanship Under Conditions of Glare and a Sub-Pixel Rendering Method for Generating Vernier Acuity Targets

Abstract

Glare occurs when bright light scatters within the eye and reduces visibility of a target. This has been a known issue in military marksmanship for over a century. While many glare countermeasures related to marksmanship have been patented over the years, quantitative assessment of the impact of glare on marksmanship is conspicuously absent. To remedy this gap in the literature, novel instrumentation was created for psychophysical assessment of the impact of glare on marksmanship performance. Limitations in the experimental design lead to an early termination of human subjects data collection, but scientific findings as well as descriptions of tools developed for this research effort provide guidance for further empirical study. Additionally, a description of and source code for a sub-pixel rendering method of producing Vernier acuity targets is included.
