Abstract
Previously, it had been found that texture-coding was ineffective at reducing search time (Perlman & Swan, 1993). In the experiment reported here, 16 subjects searched for blank-, color-, texture-, and density-coded targets of varying complexity in a naturalistic task. The data showed that all non-blank methods were significantly and about equally more effective at reducing search time than blank-coding (no coding). The difference of outcome with previous results is explained by task simplification and by the control of possibly confounding factors. The difference suggests that coding techniques using texture, and possibly other methods, should be evaluated in context. The similar performance of color-, texture-, and density-coding is explained by the use of equal-saturation and equal-brightness colors. Recommendations for the design of effective coding methods and for future research are discussed.

Previously, it had been found that texture-coding was ineffective at reducing
search time (Perlman & Swan, 1993). In the experiment reported here, 16 subjects
searched for blank-, color-, texture-, and density-coded targets of varying
complexity in a naturalistic task. The data showed that all non-blank methods
were significantly and about equally more effective at reducing search time than
blank-coding (no coding). The difference of outcome with previous results is
explained by task simplification and by the control of possibly confounding
factors. The difference suggests that coding techniques using texture, and
possibly other methods, should be evaluated in context. The similar performance
of color-, texture-, and density-coding is explained by the use of
equal-saturation and equal-brightness colors. Recommendations for the design of
effective coding methods and for future research are discussed.
