Abstract

A new model of the visual search process is developed which can improve the design of large symbol sets such as those used by nuclear power plant personnel, air traffic controllers, and battlefield troops. An experiment was conducted to determine whether the new, componential model or an already existing, discriminability model better explains visual search behavior. The results were consistent with the componential model. We show how to use the componential model to help automate selection of the optimal symbol set (i.e., the symbol set that minimizes the average time to find a target).
