Research Question

How to make existing CAD visualizations help with change detection and control?

Proposed solutions

Changes visualization mode on Symbolic Diagram:1. Dynamic Query: what is effected?2. Visualization Guage: how it is effected?

InfoViz principles:o Filteringo Importance-Driven Visualizationo Focus/Emphasis

Demo

Evaluation of solution

Participants - CAD research group. "controlled experiment" - with and

without proposed method. Measure
