This paper describes the strengths of two types of visual aids: VADS (Visualization of Agent Decision Space) and ADT (Agent Decision Table). The VADS 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 real-time 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.
