Comparison of SA Measurement Techniques in a Human-Robot Team Task

Increasingly intelligent and capable robots may lead to human-robot interaction characterized by close collaboration with robots as team members rather than remotely manipulated tools. In this mode of operation, it is important that robot team members contribute to, rather than limit, the situation awareness (SA) of soldiers. An exploratory study was conducted in which the effects of individual differences and mission factors on three measures of SA were compared. The Situational Awareness Rating Technique (SART) was the best metric for capturing elements of SA that were useful in mission performance, although the results suggest that other measures should not be disregarded. Practical implications for the use of SA metrics in human-robot teams are discussed
