1 2D & 3D Information Visualization: The Next Big Revolution Brad Eden, Ph.D. Associate University Librarian for Technical Services & Scholarly Communication University of California, Santa Barbara

2 What is Information Visualization? The use of computer-supported, interactive, visual representations of abstract data to amplify cognition. From Readings in Information Visualization: Using Vision to Think. Edited by S. Card, J. Mackinlay, and B. Shneiderman. San Francisco: Morgan Kaufmann, p. 6

3 Other definitions from the literature… The process of analyzing and transforming nonspatial data into an effective visual form A highly efficient way for the mind to directly perceive data and discover knowledge and insight from it The visual appearance of data objects and their relationships The transformation of abstract data to a visual representation, which is rapidly understood by the user

4 Why is it important? Human beings are tremendously influenced by sensory perceptions… The way that we learn, grow, understand, and adapt is based on our ability to view, perceive, and conceptualize thoughts and ideas… The power to visualize and graphically represent results, ideas, solutions, and problems in multiple dimensions, as well as to manipulate data and virtually collaborate with others, is the next big revolution in technology.

5 Tell me and Ill forget… Show me and I may remember… Involve me and Ill understand. Ancient Chinese proverb

6 Who is doing it right now? Your users everyday –Students Virtual collaborative gaming Collaborative spaces on the Internet On their Gameboys and home entertainment systems –Faculty In the sciences (David Rumsey Map Collection at In medicine (Visible Human Project at ) In history ( )

7 Areas of study already established in visualization… Data visualization Geographic visualization Scientific visualization Software visualization

8 Dimensional types of information visualization Temporal One-dimensional (1D) Two-dimensional (2D) Three-dimensional (3D) Multi-dimensional (MultiD) Tree Network Workspace See Olive: On-line Library of Information Visualization Environments at

9 3D information visualization presentation techniques Benediktine space Cityscapes Cluster maps Concept mapping Fish-eye views Graphs Landscapes Networks Perspective walls Rooms Spheres Topic maps Trees

10 Programming languages for 3D Virtual Reality Modeling Language (VRML)/eXtensible 3D (X3D) Scalable Vector Graphics (SVG) Many other ones, by gamers and techies

11 An Atlas of Cyberspaces Provides examples of graphic representations of cyberspaces like the Internet, the World Wide Web, and other digital environments. Divided into topics such as historical, geographical, MUDS and virtual worlds, weather maps, conceptual, surfmaps, website maps, artistic, cables and satellites, topology, census, etc.

CLIR, February 2005, p pdf Bernard Frischer. From CVR to CVRO: The Past, Present, and Future of Cultural Virtual Reality. 20to%20CVRO.pdf

20 From CVR to CVRO: If the ten-year rule of thumb holds true, personal computer enthusiasts by the millions a decade from now will be interacting directly with virtual worlds through their desktop reality engines. Howard Rheingold (1991)

21 Also from CVR to CVRO: All men by nature desire to know. An indication of this is the delight we take in our senses; for even apart from their usefulness they are loved for themselves; and above all others the sense of sight. For not only with a view to action, but even when we are not going to do anything, we prefer seeing (one might say) to everything else. The reason is that this, most of all the senses, makes us know and brings to light many differences between things. Aristotle, Metaphysics 980a (ca. 330 B.C.)
