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). WWW: http: //ella. slis. indiana. edu/~katy/Info. Vis

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

LVis: 3 -D Data Visualization “head” into a search result - “get inside a head”

LVis: Usability Studies n n n 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 i. Palace and i. Garden 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 University’s 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 3 D web-based collaboration mechanism for all IU faculty, staff and students on any of the eight IU campuses, located throughout the state of Indiana. http: //iuni. slis. indiana. edu/
