Our research extended existing cognitive task and work analysis techniques in order to apply them to the Chemical, Biological, Radiological, Nuclear and Explosive (CBRNE) incident response and Wilderness Search and Rescue (WiSAR) domains. The Goal-Directed Task Analysis and modified Cognitive Work Analysis methods were extended to accommodate these large systems in which humans are considered system components, rather than system users. The analyses elicited knowledge capturing unobservable cognitive processes, decisions, and judgments representing expert system performance that must be considered when developing a new system incorporating robots.

We developed the Cognitive Information Flow Analysis (CIFA) to combine the results from multiple analyses in order to understand how information will be used, communicated and transformed in a new system. Traditionally, robotic systems and HRI have been designed and developed with very little input from actual users. While researchers have begun to incorporate an analysis of users into the robot system development process, our effort is the first to apply analyses to the CBRNE domain, before beginning the robotic system design. The GDTA, modified CWA and CIFA results are directly impacting the design and development of our system of human-robot interfaces.

The goal of our efforts are to identify necessary information to guide the design and development of robotic and HRI technologies. Our work in this area can be decomposed into three primary areas.
