Designing an Information Visualization Tool for Sensemaking

Abstract

The study presents the AVALANCHE visualization test-bed for sensemaking in illstructured problem domains. AVALANCHE allows the users to develop and frame hypotheses, analyze the hypotheses in the experimental domain, and provide cases for simulation experiments. The visualization and sensemaking support module in AVALANCHE provides human-computer interface and visualization supports. Validation experiments using groups aided with visualization and support tools and groups with no aiding was performed on two open-ended sensemaking cases provided by a military subject matter expert. Statistical analyses revealed mean performance differences in plan accuracy, plan time, and number of cue prompts between aided and unaided groups across task scenarios. In general, the aided group had the highest mean plan outcome accuracy, low planning time, and the least number of prompts. The intention is to extend the study to collaborative sensemaking tasks to address the effects of negotiation on team planning time, cue prompting frequencies, and different types of cue prompting modalities.

INVISQUE as a Tool for Intelligence Analysis: The Construction of Explanatory Narratives

“…Similarly, the Entity Workspace provides an evidence panel for analysis to place relevant documents and generate hypotheses (Billman & Bier, 2007), whilst Dynapad offers a workspace for spatially organising personal document collections (Bauer, Fastrez, & Hollan, 2005). Finally, the S3 system embeds cognition into a visual interface for developing and analysing hypotheses (Ntuen, Park, & Gwang-Myung, 2010).…”

A Comparative Study of Three Sorting Techniques in Performing Cognitive Tasks on a Tabular Representation

“…Several frameworks have been suggested to explain why visual representation could enhance performance (Jun, Landry, & Salvendy, 2011;Ntuen, Park, & Gwang-Myung, 2010). However, studies comparing graphs and tables reported mixed results: Some reported that graphs are better than tables, but the others reported opposite results.…”

A cognitive prosthesis for complex decision-making

“…Joint cognitive systems are widely used in the support of performing complex tasks including air traffic control (e.g. Harris 2013;Hollnagel 2007), emergency and crisis management (e.g., Furniss and Blanford, 2006;Ntuen et al, 2006), warehouse management (Accorsi, Manzini, and Maranesi, 2013), and policy making (Ntuen, Park, and Gwang-Myung, 2010;Parsons and Sedig, 2014). Our results also suggest that joint cognitive systems may be insufficient for human users to develop a good internal representation of a complex situation.…”
