1. Applications and Implications
Seth Hettich

2. Applications of info visualization
Statistical and categorical data
Digital libraries
Personal Services
Complex Documents
Histories
Classifications
Networks

3. 2D vs. 3D The “real” world is 3D People are used to 2D UI
Monitors are 2D
3D tech is improving
3d tech has been “improving” for 10 years
Compromise?

4. Uses for 3D Immersive virtual environment Semi-immersive environment
Desktop 3D for 3D worlds
Desktop 3D for atrifical worlds
Desktop 3D for novel info spaces
Are any better then 2D?

5. Overview+detail vs. Focus+context
two windows, one for overview, one for data
Focus+context
show detail at focus point
show overview all around it
Which is better?

6. Reengineering the desktop
Many visualizations attempt it
3D world
Zooming UI (pad++)
hierarchical visualizations
Are any better then overlapping windows?

7. Future trends (1999) Entering the mainstream
Moving towards applications
Integrated packages
Networks
Education
How good was the prediction?

8. Unsolved problems New metaphors / New visualizations Formal analysis
Visualization of the Internet
Collaborative visualizations
Science of spatial cognition
theory of knowledge crystallization
