What is Infoviz?

• visual representations of the semantics, or
  meaning, of information.
• information visualization typically deals with
  nonnumeric, nonspatial, and high-dimensional
  data.

3
1. Usability

• More empirical studies
• New study methodologies
• Mostly limited to the particular systems at hand

4
2. Understanding elementaryperceptualcognitive
tasks

• End users cant see how their raw data is turned
  into colorful pictures
• Need to evaluate newer systems for higher level
  cognitive advantages

2. Understanding elementaryperceptualcognitive
tasks

• Measure
• Spatial ability
• Eye movement

4. Education and training

• Sharing principals of infoviz among researchers
• Raise awareness of the importance of Infoviz.
• Good applications?

8
5. Intrinsic Quality Measures

• Need more effective measures and benchmarks

6. Scalability

• Infoviz hasnt used massively parallel computing
  techniques.
• Data streams (real time data?)
• Urgency
• arrival pattern

7. Aesthetics

• What makes the viz pretty?
• Linked to usability
