Visage: An AllinOne Tool

1
Visage An All-in-One Tool

• A Paper by Roth, Lucas, Senn, et al.
• Presented by Josh Steele

2
Lots of Good Things Out There..

• Table Lens
• Focuses attention on subsets while still seeing
  the context
• IVEE
• Rapidly creates multiple DQ sliders
• SAGE
• Rapid Design of visualizations that integrate
  multiple attributes

3
I want all that and more.

• Select info from multiple apps, visualizations
  and tools and combine them
• Enable rapid generation of visualizations (on the
  fly!)
• Filter, control level of detail, navigate, create
  new info whenever needed
• Share and communicate information

4
Introducing Visage

• Information Centric paradigm (more on this next
  slide)
• Dynamic Visualization Generation
• Interactive Info manipulation
• Partitioning, filtering, combining, detail level
  (drill down/roll up)
• Assembling, laying out and interactively
  presenting info to others

5
Centering in on Information

• Application-Centric
• The File is the object need applications to
  retrieve and display
• Users cant touch data
• Document-Centric
• Document is the object, and can be directly
  manipulated
• May serve as containers for other objects
• Can visualize relationships between documents
• Users can get their hands on the documents
• Information centric
• The data element is the object
• Drag and drop at any level of granularity
• OO approach introduced in Smalltalk et al
• Used in Visage

Demo Presentation

• Please see in-class TV
• An abbreviated version is available at
  http//www.cs.cmu.edu/sage/animations/Visage3.dcr

Main Components

• Elements
• The atomically-manipulable graphical objects
• Bars in bar chart, text label, point in a chart
• 1 to many relationship one database element may
  be represented in many ways
• Frames
• Hold the elements (are actually elements
  themselves)
• Provide grouping and reference for elements
• Serve as anchor points for scripts (which guide
  most of Visages behavior)
• Scripts allow new values to be calculated

8
Show it off!

• Presentation tools built in
• Allows interactivity in the slides themselves!
  Each slide is a fully functional Visage frame

9
Visage! Whats it good for?

• Representing data in several views (not just in
  your typical charts(pie, bar, etc))
• Dynamic Queries on that data
• Quick presentation generation (with interactivity
  during the presentation)
• Selecting only certain information

10
HCI Metrics

• User Performance - ??
• Error Recovery - ??
• User Satisfaction - ??
• Learning Time -
• Retention -

11
How does it compare?

• Number of variables?
• Number of data points?
• Pixel use?
• When would you not use this?
