The Effect of Instantaneous Field of View on Search Rate for Single Targets Over a Wide Field

Abstract

The effect of the instantaneous field-of-view in searching a complex, wide-angle field viewed at fixed resolution was examined by simulation. The results show a decelerated improvement with instantaneous field-of-view over the range 6.9 deg to 55 deg for a 55 deg search field. This improvement was attributable to increased slewing rate of the search window. Keywords: Observer's visual perception; Visual field; Visual search tasks.
