Uncertainty Visualization Study Group Notes – 12/4/2012
Zuk and Carpendale, 2006, “Theoretical analysis of uncertainty visualizations”
- Evaluation of 8 visualizations according to 3 perceptual/cognitive frameworks (Bertin, Tufte, Ware)
- Bertin:
- Two planar visual variables: x-axis, y-axis
- Six variables embedded on the plane created by the above:
- size
- value
- grain
- color
- orientation
- shape
- Tufte:
- Graphical excellence
- Greatest number of ideas in the shortest amount of time
- 6 principles of graphical integrity
- Avoid deception/misrepresentation
- Data-ink maximization
- Small multiples
- Ware: cognition/perception
- preattentive processing
- gestalt laws
- words with images–text is often superior for abstract ideas, logic, etc.
- thinking with visualization
- Methodology: Heuristic evaluation
- Bertin, Tufte, and Ware representing all perceptual/cognitive typologies
- 8 visualizations representing all visualization
