  1. CSC 8570 -- USI Class Meeting 6 September 27, 2006

  2. Themes • Models, theories, frameworks Form a foundation for understanding • What users want (What do they want?) Which is interpreted by the • Design principle hierarchy • GUEPs • General design principles • Implementable design guidelines

  3. Themes (2) Users are directed in their approach to a system by • Mental models And • The cognitive dimensions of understanding (which describes ways of thinking).

  4. Themes (3) We have devised a path from abstraction to implementation • Cognitive dimensions • GUEPs • Design principles • Task analysis

  5. Example • What do you want from a mapping system? • Does this match with what the system provides? • Explore • Mapquest • Google Maps • Yahoo Maps • Mappy.com • AAA.com • Microsoft Streets and Trips

  6. Class Exercise • Create union list of bad interface components • Describe difficulties in terms of • Failures to match design principles • Failures to build on cognitive dimensions

  7. Class Exercise Match the 14 cognitive dimensions to the 9 GUEPs looking for overlapping and orthogonal ideas. For class, you will be assigned 3 cognitive dimensions to explore. In general, see Experiment 1

  8. Experiment 1 Match the 14 cognitive dimensions to the 9 GUEPs looking for overlapping and orthogonal ideas. Create a 14 by 9 array whose cell entries describe the relationship between the ith CD and the jth GUEP

  9. Exercise For your assigned button on Windows Explorer, determine • Its syntax • Its semantics • Which cognitive dimensions and which GUEPs its behavior exemplifies. Hand in your written report next time.

  10. Back Forward Search Folders Views Go Name Size Type Date modified X (right of Folders) ↓ (next to dialog box) View File Button Assignment

  11. Next Time • Continue work on research project, completing experimental material and IRB form • Read Carroll, MTF Chapter 10 • Discover some recent results on electronically mediated communication and be prepared to describe them. • Button Exercise (see above)

  12. Research Team Meetings
