The operation of Unmanned Aerial Vehicles (UAVs) in the National Airspace System (NAS) is a growing area of research for NASA, but the need for substantial amounts of research on the UAV-in-NAS concept is overwhelming. Furthermore, the quantity and nature of research questions on UAV-in-NAS operations are somewhat unpredictable as this research progresses, thereby requiring NASA to have flexible research tools and adaptable methodologies. To address these issues, we propose to develop the UAV-TEST toolset (User-Augmented Visualizations for Targeted Evaluation of Systems and Technologies). UAV-TEST will be a user-centered methodology that helps streamline the research process for UAV-in-NAS research at NASA and enhances the process of generating and connecting new measures, research questions, and visualizations. This concept will be instantiated within a flexible, low-cost toolset that seamlessly integrates with current research tools at NASA. The ultimate goal of the UAV-TEST product is to enable researchers to obtain clear and rapid assessments of key human factors issues in simulated flight environments. In Phase I, we will design this concept and develop a proof of concept demonstration. In Phase II, we will develop a functional prototype that can be used alongside actual NASA studies, particularly within the UAV-in-NAS research areas.
