The purpose of this study was to contribute to an analytical framework for creating
and validating simulations. This was achieved by investigating viewer response
to changes of a single-image variable (field-of-view). Eight images of two different
test sites, with fields-of-view that ranged from 40 to 120 degrees, were judged by 47
people. Image representativeness was analyzed by evaluating viewer response of
the images to the actual scene. Statistical analysis revealed that simulations with
fields-of-view > 40 and ≤ 90 degrees may best represent the test sites, regardless of
the scenes viewshed. Preference ratings for the same images were analyzed and
compared with response to representativeness. The results of the study reveal no
relationship between image preference and the perceived accuracy of the images to
represent the test sites. Implications of the findings suggest further research is
needed on methods of estimating the validity of visual simulations.
