Modeling and integration of situational awareness and soldier target search

Abstract

Representation of search and target acquisition (STA) in military models and simulations arguably abstracts the most critical aspects of combat. This research focuses on the search aspect of STA for the unaided human eye. It is intuitive that an individual's environmental characteristics and interpretation of the environment in the context of all comprehended information, commonly summarized as their situational awareness (SA), influences attention and search. Current simulation models use a primitive sweeping search method that devotes an unbiased amount of time to every area in an entity's field of regard and neglects to effects of SA. The goal of this research is to provide empirical results and recommend modeling approaches that improve the respresentation of unaided search in military models and simulations. The major contributions towards this goal include novel empricial results from two incermental eye-tracking experiments, analysis and modeling of the eye-tracking data to illustrate the effect of the environment and SA on search, and a recommended model for unaided search for high-fidelity combat simulation models. The results of this work support soldier search models driven by metrics that summarize the threat based on envirnomental characteristics and contextual information.
