Abstract:
The research objectives were to compare the visual detection abilities of observers equipped with low- and moderate-powered optical systems, and to compare the detection capabilities of observers using different techniques or strategies for searching extensive visual displays. Visual experiments were conducted in a scaled reduction of an aircraft detection situation, comparing observer results using optical aids and unaided vision a general conclusion was that sharp eyes are the best visual detection aids. Several search patterns experiments compared unstructured and structured visual search for simulated aircraft targets. Fundamental characteristics of vision--visual acuity and field of view--appear to be the major sources of variance in acquiring visual targets.
