HCI and Digital Libraries
critical technological fields in the emerging Information Society
identification of synergies towards a common, international R&D agenda
how can they be designed, implemented and evaluated
- what functional & non-functional quality attributes need to be addressed
- how can diversity be accounted for
- what software components are needed
- what architectural models need to be followed
Characteristics of DLs
Distributed (across the Internet)
Large volumes of data
new range of computer-mediated human activities
HCI challenges in the context of DLs
Diverse user groups
information overload, etc.
Variety in the context of use
- Technological proliferation
- terminals (portables, network attachable equipment)
- novel input/output devises (e.g., wearables)
- new interaction platforms (e.g., Java)
- desktop versus nomadic use
- user tasks in the DL domain
- physical and social environment
Meeting the challenges
Designing for the broadest possible end-user population
studying the dimensions of diversity
- users with different abilities, requirements and preferences
- context of use
- terminals, novel platforms and network-attachable devices
- context and intend
- alternative styles for instantiating user tasks
- conveying context through assigning interaction objects to dialogue states
- Shifting the focus of implementation
- specification-based framework versus programming
- tools for developing interactive software

Common themes (from the ECDL 98 Proceedings)
- User interface adaptation
- User interface agents
- User modelling components
- Metaphors, including visualisations
- Virtual reality
- Information retrieval
Design processes & techniques
- Human-centred design (ISO 13407) fosters
- usability focus
- iterative evaluation-feedback loops
- techniques to attain the above
- Is "usability" (as approached today) enough ?
- What about quality (functional & non-functional attributes) ?
- Do existing UCD techniques cope with design pluralism ?
- Do existing UCD techniques offer process-oriented support ?
- e.g. unfolding, capturing and maintaining design rationale
- Tool requirements
- support for collaboration
- sharing knowledge and experiences, etc.
- What is the role of software architectures ?
- Does evaluation ever lead to innovative designs, or does it simply help identify design defects ?
- How can one evaluate some of the non-functional quality attributes which are critical to DLs ?
Bridging across the two communities
Exchange of experience and establishment of common ground
Developing a common vocabulary
Focusing on a common research agenda
- EC 5th Framework Programme
- ERCIM WGs
- Joint session of the ERCIM Delos Workshop and ERCIM WG UI4ALL (Stockholm, 21 October 1998)
- White Paper - "HCI in DLs: An International R&D Agenda"
