  • ADVANCED techniques to support THE DESIGN OF WEBSITES INFORMATION ARCHITECTURE BASED ON MODELS OF HUMAN-INFORMATION INTERACTION
    Christos Katsanos (ckatsanos@ece.upatras.gr)
    HCI Group, University of Patras, Greece
  • Purpose & Motivation
    Increase objectivity & efficiency for the design & evaluation of websites information organization
    Aspects addressed
    Structural design
    Links’ Labeling
    Both aspects addressed greatly affect User Experience
    Existing approaches are often neglected:
    Time & Cost constraints
    Increased complexity of data analysis
    Large & Rapidly-changing web sites
    Hard to go from user-research to the design itself
  • Proposed approach at a glance
    Two tool-based methods:
    Automated Card Sorting Tool (AutoCardSorter)
    InfoScent Evaluator Tool (ISEtool)
    Based on
    Information Foraging Theory
    Semantic Similarity Algorithms (e.g. Latent Semantic Analysis)
    Mathematical/Statistical techniques (e.g. cluster analysis, eigenvalue analysis)

  • 2 Validation Eye-Tracking Studies
  • Advantages of proposed tool-based approach
    Cost-effective (time & resources)
    Explore alternative solutions early
    Simple to learn and apply
    Easy to apply for large sites (>100)
    Can be easily incorporated in popular web development IDEs
    Valuable for sites that have totally unfamiliar domain to the practitioner
    Possibility for wider adoption
    Complementary to user-based methods
