Aims
The primary aim of the workshop is to raise the awareness of several interconnected fields of research related to the design and use of visual interfaces to digital libraries, especially in information visualization, human-computer interaction, and cognitive psychology. This workshop also aims to stimulate participants to reflect on the state of the art in their own fields by identifying challenging issues concerning visual interfaces and thereby fostering a multidisciplinary research agenda for future research and development. 

Objectives

• To provide a stimulating forum for researchers in information visualization and digital libraries to share their views, experiences, and plans.
• To raise the awareness of the state of the art in related fields of research.
• To identify a research agenda concerning the role of visual interfaces in digital library research.
• To exploit potentially useful theories, methodologies, and technologies.
• To establish long-term interdisciplinary collaboration between researchers from different fields.

• Web based Visual Interfaces
• Mobile Access to Information
• Collaborative Document Spaces
• Usability and Formal Methods - see also JCDL-WS on Usability for Digital Libraries 
• Real World Needs, Products & Applications

JCDL Workshop Prelude on July 17th
A workshop prelude that aims to facilitate the cross-fertilization of topics presented at four JCDL WSs will take place on July 17th, 5:30-7:30pm in the Hawthorne Room.
It features short overviews of the WS topics as well as talks, presentations, and demos of four workshops:

• Document Search Interface Design
• Usability of Digital Libraries: Dumas & Plenacoste will give a talk on "Libraries: comparisons between real and virtual"
• Visual Interfaces to Digital Libraries (slides): Mike Christel, CMU will present new results from the DLI-2 funded project "Auto-Summarization and Visualization across Multiple Video Documents and Libraries" 
• Digital Gazetteers (slides): Integration into Distributed Digital Library Services: Introduction to digital gazetteer components of digital libraries and an example of an application.

Keynote speaker: Tim Bray, Antarcti.ca Systems
Title: Design Criteria for Visual Interfaces to Anything
Abstract: We assume that Visual Interfaces are a necessity for the Digital Library.  In fact, the Antarcti.ca project goes further in the belief that visual interfaces are appropriate for almost any dataset too big to display on a single screen.  But there are dangers: first, there are really bad reasons to engage in visualization.  Second, where visualization is appropriate, it's possible to build a really bad interface.  In this presentation we lay out a set of criteria, first for where visualization is appropriate and second, what are the criteria for excellence in doing it. We draw on the work of Edward Tufte and other pioneering thinkers in the general area.
Bio: Tim Bray has 20 years of experience in software, almost all of it related to textual applications and search.  In 1987 he managed the New Oxford English Dictionary Project at the University of Waterloo; in 1989 co-founded Open Text Corporation; in 1994 built one of the first commercially successful Internet Search Engines; in 1996-99, as an invited expert at the W3C, co-invented XML; and in 1999 founded Antarcti.ca Systems.
Antarcti.ca's highly scalable Visual Net software powers in PubMed, Map.Net, and VCDeal map.
