Effect on target detection of isolating the target bearing area on a waterfall display with a neutral filter /

DiVita and Hanna (1987) have shown that target detection on a waterfall display suffers, and performance is improved if the pixels of the target bearing are displayed in red without, however, adding any additional target information.

Description
Summary:	DiVita and Hanna (1987) have shown that target detection on a waterfall display suffers, and performance is improved if the pixels of the target bearing are displayed in red without, however, adding any additional target information. The reason appears to be that the operator has difficulty in keeping the relevant bearing isolated. We tested the effect on target detection of isolating a target bearing with a neutral density filter on the face of the CRT, which dimmed the surround slightly but kept a narrow area about three pixels wide around the target bearing at full luminance. Although this improved the performance of 9 out of 12 subjects, the difference was not statistically significant.
