Mental Models, Visual Reasoning and Interaction in Information Visualization: A Top-down Perspective
Found in: IEEE Transactions on Visualization and Computer Graphics
By Zhicheng Liu, John Stasko
Issue Date:November 2010
pp. 999-1008
Although previous research has suggested that examining the interplay between internal and external representations can benefit our understanding of the role of information visualization (InfoVis) in human cognitive activities, there has been little work d...
 
SellTrend: Inter-Attribute Visual Analysis of Temporal Transaction Data
Found in: IEEE Transactions on Visualization and Computer Graphics
By Zhicheng Liu, John Stasko, Timothy Sullivan
Issue Date:November 2009

We present a case study of our experience designing SellTrend, a visualization system for analyzing airline travel purchase requests. The relevant transaction data can be characterized as multi-variate temporal and categorical event sequences, and the chie...
 
Distributed Cognition as a Theoretical Framework for Information Visualization
Found in: IEEE Transactions on Visualization and Computer Graphics
By Zhicheng Liu, Nancy Nersessian, John Stasko
Issue Date:November 2008
pp. 1173-1180
Even though information visualization (InfoVis) research has matured in recent years, it is generally acknowledged that the field still lacks supporting, encompassing theories. In this paper, we argue that the distributed cognition framework can be used to...
