Mutual Awareness as a Basis for Defining and Assessing Team Situation Awareness in Cooperative Work
Our research program is finding out the underlying mechanism of Team Situation Awareness (TSA) and focushg on how to effectively incorporate between human teams and artifacts. In this paper, we argue that the earlier models of TSA, which have been discussed as an intersection of situation awareness (SA) owned by individual team members, are inadequate for study of sophisticated team reciprocal process. We suggest that the definition of TSA is necessary to integrate the notion of individual SA to cooperative team activity. We propose a new notion of TSA, which is reducible to mutual beliefs as well as individual SA in three levels. Then, we develop a feasible TSA inference approach and discuss human competence required to build TSA Through field study, we try to demonstrate how TSA is actively constructed via the inferring practices.
