Situational Awareness through Augmented Reality: 3D-SA Model to Relate Requirements, Design and Evaluation

This paper presents a proposal of a model for identification, selection and classification of Situational Awareness (SA) requirements together with the design of AR-based solutions. In this way, a three dimensional model that considers three main elements: SA phase, SA characteristics and interaction modality is introduced. This 3D-SA model facilitates the analysis, first, and the design later, of systems where the concept of SA is essential. The presented 3D-SA model tries to facilitate the use and application of AR-based solutions for SA for different kinds of stakeholders (developers, maintainers, etc.) as well as to cover a deficiency in the gap between SA requirements and SA design solutions. A particular use of the 3D-SA model in the military field is presented.
