Dynamic Visualizations - Table Lenses - Hyperbolic Trees


Description:

"Information Visualization: The use of computer-supported, interactive, visual representations of abstract data to amplify cognition." (Card et al, 1999, p. 7) "Information visualization combines aspects of scientific visualization, human-computer interfaces, data mining, imaging, and graphics."(Gershon et al, 1998, p.10) With the advent of powerful computers and 3D modeling software, designers now have the tools to create complex visualizations that can be scaled and rotated to display the relationships and comparisons between data.

Other dynamic visualization formats:
Table lenses, hyperbolic trees and webs, multidimensional visualizations, orthogonal visualizations, fly-overs, fisheye lenses, distortion lenses

Strengths:

  • Allows user to zoom in for detail and zoom out for patterns
  • Helps the user filter and find information in huge databases
  • Draws on spatial and retinal cognitive ability

Uses:

  • Exploration
  • Scenario casting
  • Navigation of vast databases
  • Data mining and filtering
  • Interactive diagrams
  • Large-scale data monitoring
  • Scientific visualization

Weaknesses:

  • Deskilling
  • "Garbage in - garbage out"
  • Potential to "get lost" in the data
