We are investigating what makes good user interfaces for operators in Urban Search and Rescue. We have collected data in the NIST Standard Test Arenas during competitions and during other experiments. We have our own robot and we are prototyping a number of different interfaces to use in experiments. We have used critical incident analysis to investigate situational awareness provided by different user interfaces. Under Department of Homeland Security Funding, we are working with FEMA teams to define standard methods for evaluating the human factors of robot platforms
