Visage An AllinOne Tool A Paper by Roth

Visage: An All-in-One Tool A Paper by Roth, Lucas, Senn, et al. Presented by Josh Steele

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

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

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

Centering in on Information • Application-Centric – The File is the object – need applications to retrieve and display – Users can’t “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/Visage 3. 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 Visage’s behavior) • Scripts allow new values to be calculated

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

Visage! What’s 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

HCI Metrics • • • User Performance - ***? ? Error Recovery - ? ? User Satisfaction - ? ? Learning Time - *** Retention - ****

How does it compare? • Number of variables? • Number of data points? • Pixel use? • When would you not use this?
