challenges in visualization
Challenges in Visualization
  • Novel Imaging Modalities
  • From Data Fusion to Visual Fusion
  • Visual Computing
  • Illustrative Visualization
  • Visualization Yes ! – Interaction No ?
  • Interaction Yes ! – BUT User centric !

Eduard Gröller

visualization yes interaction no
Visualization Yes ! – Interaction No ?
  • Problems
    • Interaction is very time-consuming
    • Interaction prevents comparisons
    • Interaction hampers reporting
  • Challenges
    • Provide standardized views
    • Algorithms highly parameterized – provide sensible default settings
    • Support automatic parameter tuning
    • Provide navigational aids
  • Examples
    • Automatic view point selection
    • Focus of attention
    • Automatic light placement (inconsistent lighting)
    • Automatic reporting
    • Dynamic poster - automatic storytelling

visualization yes interaction no1

Provide the user with the flexibility he/she can cope with

avoid the terror of unconstrained liberty

Visualization Yes ! – Interaction No ?

  • Visualization Yes ! – Interaction No ?
  • Interaction Yes ! – BUT User centric !

Eduard Gröller

interaction yes but user centric
Interaction Yes ! – BUT User Centric !
  • Problems
    • Medical doctors do not (want to) know transfer functions
    • Complex 3D interaction is complex
  • Challenges
    • Include user model (novice, experienced, expert)
    • Include motifs
    • Include user preferences
    • 2D+ navigation (instead of 3D navigation)
  • Examples
    • Semantic layers for illustrative volume rendering
    • Knowledge-based navigation

Eduard Gröller

semantic layers for illustrative volume rendering 1
Semantic Layers for Illustrative Volume Rendering (1)
  • Mapping volumetric attributes to visual styles
  • Use natural language of domain expert (rules)
  • Rules evaluated with fuzzy logic arithmetics

[Rautek et al. 2007]

knowledge based navigation 1

Long term goal: Interaction at

sub-pick

resolution

Knowledge-Based Navigation (1)
  • Interaction with 2D slices
  • Automatic generation of expressive 3D views

Visualization – I see it my way IIAction without Interaction
  • Abstract: Visualization provides computer-supported tools to enable users with insight into their data. Over the last 25 years visualization as a discipline has come a long way in terms of maturity and in providing a rich set of algorithms and systems for visual exploration, analysis, and presentation of data. Interaction is considered a key component in the analysis process. The talk will argue for a sparse and cautious usage of interaction in visualization. The importance of a user centric structuring of interaction functionality will be illustrated with several research examples from our group.
