  1. Making Usability Engineering a Little EasierTools for electronic card sorting and collecting usability test data Todd Zazelenchuk, Ph.D., UITS, Indiana University Nate Johnson, UITS, Indiana University

  2. Collecting and analyzing usability data • Measuring usability • Quantitative: Effectiveness, Efficiency, Satisfaction • Qualitative: Think aloud protocol, direct observation • Reasons for building the tool • Collating, analyzing, and summarizing paper notes • Speeding up the data analysis process • Recording quantitative measures consistently • Desired a cross-platform tool for our lab

  3. Ulab data collection tool • Excel spreadsheet with VB macros • Allows researcher to: • Record time per task • Record observations on task performance and behavior • Record users satisfaction scores • View summary charts of key usability criteria • View summary of qualitative data on a per task basis

  4. DEMO…

  5. Card Sorting for WWW content organization • Card sorting • Used to identify users’ preferred arrangement and naming of content for a website • Users group paper index cards into piles and name them • Researchers ‘eyeball’ results or perform cluster analysis • Reasons for building the tool • Reduce reproduction and management of cards and data • Allow remote participants to be involved • Improve on stability and accessibility of current tools • Improve on usability and analysis capability

  6. Grouper: Card Sorting Tool • Java Application • Requires the Java SDK 1.4 • Cross platform: • Windows, Mac OS X, Unix flavors • Simple XML file format for easy incorporation into other applications • Deployed via Java WebStart • Currently in an alpha state, beta coming soon
