ABSTRACT
Situation Awareness (SA) is the term that is used within Human Factors circles to describe the level of awareness that operators have of the situation that they are engaged in; it focuses on how operators develop and maintain a sufficient understanding of “what is going on” (Endsley, 1995b) in order to achieve success in task performance. A critical commodity in the safety critical domains, SA is now a key consideration in system design and evaluation (Endsley, Bolte, and Jones, 2003; Salmon et al., 2009). Accordingly, various theoretical models have been postulated in relation to individuals (e.g., Endsley, 1995b; Smith and Hancock, 1995), teams (e.g., Endsley and Robertson, 2000; Salas, Prince, Baker, and Shrestha, 1995), and systems (e.g., Artman and Garbis, 1998; Stanton et al., 2006). Further, various measurement approaches have been developed and applied in a range of domains (e.g., Endsley, 1995a; Hogg, Folleso, Strand-Volden, and Torralba, 1995; Stanton et al., 2006).
