Detection Rate and Sweep Width in Visual Search
Marc Mangel, Davis K. Cope · 1979
The relationship between sweep width and detection rates is re-evaluated. The result derived in OEG Report 56, W approximately 2(2 pi KH/V sub R) to the 1/2 power, is the leading term in the asymptotic expansion of the exact solution. This result is valid when a non-dimensional parameter, alpha equal to KH/V sub R, is large. When q is small, W approximately 2 Pi H.
