IAT 814 KNOWLEDGE VISUALIZATION & COMMUNICATION COURSE FINAL PROJECT Diliara Nasirova Changes detection and control in 3D Parametric Systems via Symbolic Diagram

Presentation Outline 1. Context 3D parametric modeling Symbolic Diagram (SD) 2. Problem Changes detection and control on geometry 3. Solution Changes propagation visualization on SD

Context - 3d parametric modeling

Symbolic Diagram  DAG that:  Shows dependencies features  visually expresses relationships

Symbolic Diagram

Problem  Change detection and control on geometry: Change magnitude is small. Zoom factor and model size. Occlusion. Multiple locations. hain of changes. Change blindness.

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 Filtering o Importance-Driven Visualization o Focus/Emphasis  Demo

Evaluation of solution  Participants - CAD research group.  "controlled experiment" - with and without proposed method.  Measure  Completion  Time  Satisfaction  # changes detected…
