Abstract:

This report describes an experiment to compare the perceived size of collimated and uncollimated aircraft targets presented on typical flight simulator background imagery. It has recently been suggested that magnifying the size of imagery might improve the spatial detail of simulated targets. Such a magnification would also render uncollimated targets perceptually more similar in size to collimated targets. It has been questioned, however, whether a magnification using a viewing distance of 44 inches should be applied to a visual display system whose viewing distance is only 28 inches. The present experiment was performed to answer this question.
