The Sandbox is a flexible and expressive thinking environment that supports both ad-hoc and more formal analytical tasks. It is the evidence marshalling and sensemaking component for the analytical software environment called nSpace. This paper presents innovative Sandbox human information interaction capabilities and the rationale underlying them including(More)
TRIST (“The Rapid Information Scanning Tool”) is the information retrieval and triage component for the analytical environment called nSpace. TRIST uses Human Information Interaction (HII) techniques to interact with massive data in order to quickly uncover the relevant, novel and unexpected. TRIST provides query planning, rapid scanning over thousands of(More)
GeoTime and nSpace are new analysis tools that provide innovative visual analytic capabilities. This paper uses an epidemiology analysis scenario to illustrate and discuss these new investigative methods and techniques. In addition, this case study is an exploration and demonstration of the analytical synergy achieved by combining GeoTime’s geo-temporal(More)
The nSpace and GeoTime visual analytic tools enable investigation and understanding of complex, ambiguous situations. nSpace is a system of systems supporting the whole analytic workflow. GeoTime provides insight into events and behaviors in time and space. Junior analysts used the analytic capabilities that these tools support to investigate the 2006(More)
