2. Welcome! To the First International Workshop “Visual Interfaces to Digital Libraries – Its Past, Present, and Future” at the First ACM+IEEE Joint Conference on Digital Libraries JCDL WS Visual Interfaces to Digital Libraries

3. Why visual interfaces now? Today’s digital libraries are • Content rich, multimedia, multilingual collections. • Distributed and accessed world wide 24/7. • Huge & growing. Visual interfaces to DLs draw on progress in the new field of Information Visualization. Major strategy: Shift user’s mental load from slow reading to faster perceptual processes such as visual pattern recognition. JCDL WS Visual Interfaces to Digital Libraries

4. Information Visualization “… is a process of transforming data and information that are not inherently spatial, into a visual form allowing the user to observe and understand the information.” (Source: Gershon and Eick, First Symposium on Information Visualization) “… the use of computer-supported, interactive, visual representations of abstract data to amplify cognition.” (Source: Card et al., Readings in Information Visualization) JCDL WS Visual Interfaces to Digital Libraries

5. Facts about Information Visualization • Rooted in geography, scientific visualization. • Not even 10 years old. • Growing fast. • Far reaching (IR, WWW, DL, HCI). • Interdisciplinary nature: computer graphics, electronic engineering, information systems, geography, information science, … • Tremendous potential to improve/change information access, process, management. JCDL WS Visual Interfaces to Digital Libraries

6. Information Visualization is facilitated by • Decreasing cost of storage and computing power. • The explosion of information available digitally (on the WWW). • Fast graphics processors. • Larger hard disk sizes -> more information available quickly. • High resolution color monitors. • Alternative user interfaces Idesk, CAVE (2 hands, audio, 3D). • Rapidly expanding connectivity between systems. • Work is becoming more ‘knowledge-oriented’. • Increasing visual intelligence. • The mismatch between computer displays and the human perceptual system. • The mismatch between computer controls and human motor functions.

7. Well designed visualizations … • Reduce visual search time (e.g. by exploiting low level visual perception). • Provide a better understanding of a complex data set (e.g., by exploiting data landscape metaphors). • Reveal relations otherwise not being noticed (e.g., by exploiting the mind’s ability to see relationships in physical structures). • Enable to see a data set from several perspectives simultaneously. • Are effective sources of communication.

8. Pre-attentive processing Count the 4’s in the table. Lightness is pre-attentively processed. So are line orientation, curvature, length, width, size, collinearity, spatial grouping, added marks, numerosity, color hue, intensity, motion, stereoscopic depth convex/concave shape from shading, … JCDL WS Visual Interfaces to Digital Libraries

11. Why Visual Interfaces for DL’s? • To create intuitive user interfaces. • To provide rapid and efficient access to enormous amounts of multi-media knowledge and information. • To analyze document collections in new ways. • To leverage information (annotations, digital dog ears, footsteps) from previous users. • To facilitate information sharing & collaborations.

15. Invited Talk Visualizing On-line Activity Stephen G. Eick, Visual Insights http://www.visualinsights.com/ Dr. Eick has served as the founder and CTO of Visual Insights since its inception in 1997. He was hired as part of Bell Labs in 1991 with the charter of creating and managing the data visualization research group. His research has focused on creating novel, interactive visualization to extract information latent in large databases.
