LVis - Digital Library Visualizer (1999/2000)

• Investigators Katy Börner Andrew Dillon, SLIS
  Margaret Dolinsky, School of Fine Arts, IU
• LVis aims to support the navigation through
  complex information spaces. It provides a
  multi-modal, virtual reality interface that maps
  data stored in digital libraries onto an
  'information landscape'. This landscape can then
  be explored by human users in a natural manner
  that will support efficient search through
  related articles. The 2-D and 3-D prototype
  visualizes search results from the Dido Image
  Bank, Department of the History of Art, IU.
• The research was supported by a High Performance
  Network Applications grant of Indiana University
  (1999-2000).

Lvis - Motivation

• Present search results not as
• rank-ordered lists of matching documents
• but as
• clusters of semantically similar documents

4
LVis Data Analysis

• Latent Semantic Analysis
• Hierarchical Clustering
• Selection of Best Partition

LVis Usability Studies

• Comparison of text-based and 2-D desktop
  interface and 3-D immersive CAVE interface.
• Error rates and completion times for a range of
  different tasks.
• Learning curves (2-D visualization Wand).
• Navigation in 3-D.
• A comparison of free sorting results for images
  by human subjects and by Latent Semantic Analysis.

Collaborative Information Spaces (2001-present)

• Investigator Katy Börner, SLIS, IU
• Collaborators Sy-Miaw Lin, Yu-Chen Lin, Ying
  Feng, Min Xiao
• iPalace and iGarden are twin worlds used to
  design and evaluate a shared resource of online
  documents for faculty and students at the School
  of Library and Information Science at Indiana
  University. It will be seeded with about 8,000
  links to online documents (text, images, video,
  software demonstrations, etc.). The links will be
  collected from personal favorites or bookmark
  lists. About 300 people will have access to this
  space although we expect less than 20 to be
  logged on at any point in time.
• The research was supported by a High Performance
  Network Applications grant of Indiana University
  (2000-2001) and an Academic Equipment Grant by
  SUN Microsystems.

Collaborative Information Spaces
Memory Palaces Provide intuitive, efficient, and
collaborative document access for a scholarly
community.
Mirror Gardens Visualize user interaction data
to evaluate the effectiveness and usability, to
optimize design properties, or to examine
the evolving user community of a world.

Indiana Universitys Collaborative Information
Universe (2001-present)

• This project is a collaboration between the
  School of Library and Information Science and
  UITS Advanced Visualization Laboratory.
• The project's goal is to provide a 3D web-based
  collaboration mechanism for all IU faculty, staff
  and students on any of the eight IU campuses,
  located throughout the state of Indiana.
