    Usability & User-Centred Design Usability & User-Centred Design Presentation Transcript

    • Usability & User-Centred Design
      • Paper & UI Prototyping Practical (pm)Cramond/Swanston Room
      Usability & faceted search
      • Faceted Search Technology Hacking (pm)StudyPod
    • User-Centred Design & faceted Search User Interface
      Boon Low
      The University of Edinburgh
      17th May 2011
    • Outline
      User experience, usability, user-centred design
      Faceted search user interface
      Highlights from the JISC UX2 Project: Usability and Contemporary User Experience in Digital Libraries
    • Digital Library - Examples
      World Digital Library
      12/2/09
      Usability and Contemporary User Experience in Digital Libraries
    • Web Environment
      “Digital library is a resource representing the intellectual substance and services of a traditional library in digital form”
      Putting in the human contexts, broader roles
      A place for solving complex problem
      A place for social interactions
      A ‘sharium’, active workspace
    • Contemporary User Experience
      Web 2.0 - new ways providing user interface/experience
      User-centric, social networking, e.g. folksonomy
      New technologies, UI interactions: AJAX and rich application UI
      Virtual (2D/3D) environment
      User experience – a broad term
      Sum of all user interactions
      Goes beyond giving users what they say they want
      Objective (e.g. functional, usability) and subjective aspects (e.g. psychology)
      How a user feels about a system including overall perceptions
      Usability and Contemporary User Experience in Digital Libraries
      17/05/11
    • Implications
      What are the usability challenges?
      What are the usefulness challenges?
      UX2 Project attempts to answer some of these questions w.r.t. digital libraries
      A range of user research and usability studies,
      UI prototypes development
      23/02/11
    • Implications
      • Measuring and evaluating user experience
      • Usability, Usefulness, Appeal (Usability Week 2009)
      • Usable, Useful and Desirable (Jon Kolko 2010)
      • User experience goals:
      Enjoyable, satisfying, engaging, pleasurable, exciting, helpful, motivating, emotionally fulfilling, aesthetically pleasing..
      Boring, frustrating, annoying, cutesy..
      Source: Designing User Interfaces for Interactive Information Retrieval Systems, European Conference on Digital Libraries (2009)
    • User-Centred Design (UCD)
      A design process in which “the real users and their goals, not just technology, is the driving force of product development” (Rogers, Sharp, Preece)
      Characteristics:
      User research conducted early, throughout the product cycle
      Empirical measurement
      Iterative design
      User research and empirical measurement: personas, usability testing, prototype testing, contextual inquiry, survey, interviews, focus groups
    • User-Centred Design
      Similarities between UCD and agile software development methods, e.g. Scrum:
      “User Stories”
    • User-Centred Design
      Integrating UCD and agile software development to produce better quality product
      Lynn Miller and Desiree Sy approach
      Adapting Usability Investigation for Agile User-Centred Design, http://www.upassoc.org/upa_publications/jus/2007may/agile-ucd.html
    • User-Centred Design
      The key concepts of the Miller-Sy method:
      Chunking of UCD tasks (research, design, usability testing), base them around an agile implementation
      Progressive: low-fi to hi-fi usability testing and contextual inquiry.
      The Miller-Sy approach is resource intensive in terms of planning and management
      Two tracks -> two teams
    • User-Centred Design
      Fully integrated agile UCD approach:
      http://boonious.typepad.com/ux2/2011/03/agile-user-interface-development.html
    • Prototyping
      A key user-centred design activity
      So that users can evaluate and provide feedbacks on design before it gets implemented
      Various types of prototypes, not all are working software: low-fi (paper, UI wireframes), hi-fi (Ui, working software)
    • Prototyping
      UX2 is piloting Balsamiq, a UI prototyping tool for the JISC community, one-year pilot
      Try it online:
      https://www.wiki.ed.ac.uk/display/UX2/JISC+Balsamiq+Pilot
      Easy to use, collaborative – wiki use context
      Practical session this afternoon
    • Faceted Search
      A better technique for refining, narrowing (expanding) search compared to traditional methods
      Integrating searching and browsing seamlessly
      also faceted browsing, faceted navigation, guided navigation
    • Faceted Search
      Typical interaction
      • Perform a keyword search
      • Review a list of categories on a custom map (left of UI)
      • Use the categories (facets) on to refine and obtain results
      Essential component: Facets
      Each facet is advanced search shortcut
      Enable users to quickly formulate useful queries
      Support learning and exploration
    • Digital Library - Examples
      breadcrumb trail
      Europeana
      facets
    • Digital Library - Examples
      WDL

      Usability and Contemporary User Experience in Digital Libraries
    • Facet Analysis & Design
      Facet design and analysis is a key requirement of faceted search provision
      Determine what facets are appropriate
      Facet terms can be mapped from metadata, e.g. library book catalogue
    • Metadata mapping
      CERN MARC -> Solr Fields
      display fields
      facet fields
      sort fields
      text fields (search)
      Others
      library_facet
      technical format (mimetype facet)
      fulltext (inside document)
      search-all ‘text’ inc. all above text fields + fulltext
      23/02/11
    • Facet Analysis & Design
      Some sites require research efforts to derive terms (metadata not readily available)
      Standard user/content research methods: interviews, taxonomies and controlled vocabularies, content analysis, card sorting
      Types of facet:
      Hierarchy: continent & country, subject headings
      List: authors
      Binary: female|male; colour|black & white
      Range: date (last 10 years), price ($1-$10), rating (1 to 5)
    • Faceted Search Technology
      Two key components
      Custom application
      F/OSS:
      - VuFind, Blacklight
      Commercial:
      - AquaBrowser, Summon, Endeca
      User Interface: faceted search + other services
      Search infrastructure
      (Server)
      Apache Solr
      Repositories,
      Content
      Source: Stanford University, Digital Library Systems (OR10)
    • Introducing Blacklight
      Blacklight is a discovery interface for library catalogue, digital repository front-end, single-search interface
      Front-end for Apache Solr (similar to VuFind)
      UVA + Solr = UVA radiation = Blacklight!
    • Blacklight Features

      Date range limits
    • Apache Solr
      A Java-based search engine/server from Apache
      Service-oriented web application
      Built upon Apache Lucene
      A full-text search library in Java, written by Doug Cutting
      Versions also in C++, C#, Ruby, Python etc.
      • Deploy on any Java (J2EE) web container: Tomcat, Jetty, etc.
    • Why Solr?
      • Both Solr and Lucene are open source
      • Active development communities
      • F/OSS community: ~1300 emails/month (dev: 800/month)
      • Commercial support: Sematext, Lucid Imagination
      Simple and easy for developer to understand and install
      Fast and scalable: distributed search, index replication
