  1. Change Detection in 3D Parametric Systems:Human-Centered Interfaces for Change Visualization DiliaraNasirova HalilErhan Andy Huang SIAT / SFU – 5 Minutes Madness – April, 2010

  2. What? • examine the influence of change blindness in change detection while working with 3D parametric design models Detecting Change Visualizations in 3d Parametric Systems

  3. Why? • Computational-technology over the human • Challenges to detect changes • Complex Models • Change Blindness • A blink • Eye saccade • Shift • Occlusion… Detecting Change Visualizations in 3d Parametric Systems

  4. So what? • Improve change visualization features • Improve HCI design • Prevent poor design outcomes http://i229.photobucket.com/albums/ee174/ASP1001/river_tharwa_bridge2.jpg Detecting Change Visualizations in 3d Parametric Systems

  5. Experiment Design • study comparing three interfaces: • on model visualization, • on periphery visualization • combined views. Detecting Change Visualizations in 3d Parametric Systems

  6. Experiment Design Detecting Change Visualizations in 3d Parametric Systems

  7. Experiment Design Detecting Change Visualizations in 3d Parametric Systems

  8. Results • no significant difference between visualizations located on model and on periphery. • combined visualization makes it significantly easier and faster for detecting changes. • change blindness makes change detection highly challenging, slow and confusing.
