AbstractThe Phase I technical objective is to develop a detailed description of our proposed decision-centered visualization (DCV) architecture to support the dismounted land warrior. DCV will collaborate with human users and reduce their workload, byautomatically presenting the information that is needed for the current task and decision. This will leave the maximally tasked dismounted soldier better informed and with more time to engage in mission rehearsal, planning, and execution. In particular,we propose to investigate emerging technologies in the console market to identify a platform that will support graphic and computational requirements of a user-configurable C4ISR interface. Our investigation will be informed by a parallel thrust thatseeks to apply and extend the DCV architecture to the unique information requirements that will arise from the development of the FCS.The Phase I efforts will be critical in defining the software requirements for successfully visualizing and interactingwith C4ISR products in the field. Our team will use the research conducted in Phase I to plan Phase II technology concepts. The completion of the proposed work plan will permit the start of Phase II with the optimal visualization and interactionconcepts, as well as selected component hardware and software technologies.In many applications, workers in the field must make time-critical, high-risk decisions, under conditions of high workload. The proposed work will contribute to a solution fordecision-centered visualization for dismounted personnel. This applies not only in military operations but in the civilian domain as well. Examples include disaster relief and forest fire response. Advances in understanding cognitive and human factorsaspects of situation awareness and information visualization, coupled with recent developments in hardware and software for gaming technology, present the opportunity to develop a new systems approach for providing the right information at the right timefor workers in the field. Moreover, we believe it will be possible to leverage COTS hardware and software to provide a cost-effective solution. In addition to disaster relief and forest fire response are other commercial applications: police and firedepartments, hospital medical staffs, and manufacturing and industry.
