Toolkit for Tactical Visualizations that Represent Uncertainty Dynamically
Abstract
Decisions are usually made under uncertainty, so displaying uncertainty information is very important to decision-making. In the past, uncertainty information associated with tactical symbols was ignored. Recent research explored uncertainty display techniques and investigated the capabilities of the human perceptual system. However, most previous studies focused on static display, and limited techniques. In this report, we investigated dynamic display of uncertainty information of tactical symbols. A comparison study was carried out for three display methods: rectangular bar, color saturation, and blurred image. This report reviews uncertainty display methods, describes the design and development of the software toolkit, and discusses the experimental procedure and results. A new method for dynamic display of uncertainty, an automatic feature based morphing, was also developed and included in the report.
