Getting There The Ten Top Problems Left (By Jim
Foley)

• 1. Fill the gap between image-based and
  geometric modeling techniques.
• 2. Fill the gap between motion-capture animation
  and simulation/procedural animation.
• 3. Creative information visualization.
• 4. Automated creation of information and
  scientific visualizations.
• 5. Abstracting away from reality.
• 6. Display more pixels.
• 7. Display fewer pixels.
• 8. Unified graphics architectures.
• 9. User interfaces for 3D creativity.
• 10. Truly immersive virtual reality.

3. Creative information visualization

• Information visualization
  involves creating representations of
• nongeometric information
  by adding geometry to the
• information. As a simple
  example, the set of values depicted
• in a pie chart doesn't
  have an inherent geometry. The pie
• chart geometry is added to
  create the visualization. Similarly,
• the tree or graph of an
  organization chart has no inherent
• geometry, only a topology.
  The geometry positions of the
• nodes and routing of the
  arcs is added in order to display the
• chart in an aesthetically
  pleasing and informative way.
• Sometimes a partial
  geometry is explicit in the abstract
• data- for instance,
  population data is explicitly associated
• with a geographic region,
  so the issue isn't where but how to
• depict the population
  information.

Bill Hibbards Top Ten Viz ProblemsVisual
Quality ACM SIGGRAPH Vol.33 No.2 May 1999

• 1.Make the spatial and temporal resolution of
  visual displays indistinguishable from physical
  reality. Display and geometry resolution, and
  response times to user interaction, must all be
  brought to human perceptual limits.
• 2.Integrate virtual reality with physical
  reality. This means eliminating the need for
  special helmets, glasses, gloves and wands, and
  embedding displays as part of the physical
  environment.

• 3.Integrate visualization with networking, voice,
  artificial vision, computation and data storage.
• 4.Optimize physical resources used to perform
  visual interactions.

Bill Hibbards Top Ten Viz ProblemsInformation

• 5.Find effective ways to visualize numerical
  information of high dimension.
• 6.Find effective ways to visualize non-numerical
  information.

Bill Hibbards Top Ten Viz ProblemsInteractions

• 7.Find effective visual idioms for direct
  manipulation user interactions with
  visualizations.
• 8.Find effective visual idioms for collaborative
  interactions among multiple users.

9
Bill Hibbards Top Ten Viz ProblemsAbstractions

• 9.Define effective abstractions for the
  visualization and user interaction process.
• 10.Present abstractions to users in ways that
  reconcile expressiveness and ease-of-use.
