Abstract

Many operators within the battlefield find themselves unable to process all the data presented to them in the limited time available. Data fusion provides a means of reducing their workload, but can also reduce system transparency. Thus, either too much or too little fusion can lead to reduced operator situation awareness. A framework is proposed that incorporates a role for more sophisticated psychological theory when attempting to understand the consequences of data fusion technologies on SA. Four key questions are identified: How should the level of certainty in fused information be presented? How much does it cost the operator to “drill-down”? To what extent does data fusion inhibit representation change? Does data fusion ameliorate or exacerbate the consequences of interruption?
