A Computer Simulation of Visual Recognition Performance

As part of an ongoing program to develop computer models of human performance (MOPADS, Model of Operator Performance in Air Defense Systems), a computer model of visual recognition performance was developed. The model predicts the probability of an observer detecting and recognizing a target as a function of several independent variables. The values of these variables can be defined by the user (e.g., number of observers, observer's time on task) or be provided from an ongoing simulation of an air defense scenario (e.g., distance to target, target speed).
