The Future Soldier Technology (FST) Division conducts basic and early applied research in human behavior and performance and in the interaction of humans and systems. FST is headquartered at Aberdeen Proving Ground (APG), Md. Interpreting and predicting people and their behaviors requires a focus on individual and team-level multi-aspect measurement and signal processing technologies, including real-world and/or ubiquitous sensing technologies. Next-generation human capability enhancement is examined by focusing on future technologies that will rapidly enhance human capabilities, including physical and neural augmentation, neuroscience-driven approaches to augmentation and training, and understanding the interactions between training and augmentation. Research on novel interactions between Soldiers and advanced technology focuses on creating innovative approaches to multi-modal, brain-based and bi-directional interfaces and to human/technology decision making. Soldiers within dynamic heterogeneous, multi-agent teams are examined, with a focus on fundamental integration issues, in complex environments where teams of humans must work together with autonomous virtual and physical agents to achieve mission objectives. Research in mutually adaptive systems, multi-agent control and coordination, and social issues with human and non-human entities across time scales provides the foundational understanding necessary to support innovations that enhance human-system integration and performance.
