Abstract: This report addresses the fitness of using icon-based systems to support decision making within a domain where the quality and reliability of the information are dynamically changing. Specifically, the study examined the use of iconic and noniconic display forms to communicate information fidelity levels to decision makers for the purpose of supporting land navigation judgments. The results indicated that graphic and animated icons, as well as traditional digital display formats, produced accurate navigation judgments when information fidelity was high. In contrast, graphic and animated icon formats produced highest performance when information fidelity was moderate and/or low. These results are evaluated in the context of creating useful iconic display principles that may be applied to complex and uncertain decision environments where the fidelity of the information used to make decisions is in flux.
