ABSTRACT
This paper describes the strengths oftwo types of visual aids: VADS (Visualization of Agent Decision Space) and ADT (Agent Decision Table). The V ADS is a newly developed visual aid that intuitively represents complicated target attributes in a graphical form, whereas the ADT shows such things in a traditional tabular form. The strengths of each visual aid have been obtained through the analysis of realtime situational awareness queries. Graphical icons expressing multiple attributes
are useful in achieving overall situation awareness in most cases. However, there are cases where presentation by a simple text is better in recognition than that by a graphical notation. We discuss the recognition of the ethnic affiliation of crowds as an example at the end.
