  1. CSC 8570 -- USI Class Meeting 7 October 25, 2005

  2. One Minute Assessment • What are the two most important concepts that you have learned so far? • What are you most confused about?

  3. Quick Review Abstraction to implementation • Cognitive dimensions • Descriptions of ways of thinking • GUEPs • Design principles • General • Specific • Task analysis

  4. Quick Review (2) • How big, really, is A4 paper?

  5. Mental Models • As theories • As problem spaces • As homomorphisms of the physical world • Derived from language, perception, or imagination • As representations of representational artifacts (yoked state space) • As computationally equivalent to external representations (internalization)

  6. Experiment 1 For your assigned button on Windows Explorer, determine • Its syntax • Its semantics • Which cognitive dimensions and which GUEPs its behavior exemplifies.

  7. Back Forward Search Folders Views Go Name Size Type Date modified X (right of Folders) ↓ (next to dialog box) View File Experiment 1 (Buttons)

  8. Experiment 2 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. Article Presentations • Choose one of the three topic areas • Find an interesting recent (last 4 years) paper in the area • Prepare a 20 minute presentation of the paper • The background • The experiment • The results • The critique

  10. Article Presentations (2) • Subject areas: • Intelligent user interfaces (IUI) • Tiny user interfaces • Examples: PDA, cell phone, camera, IPod • Catch phrase: opportunistic annexing • Participatory design • Users involved at all stages of system development

  11. Research Project • Progress reports (PR 1 due next time) • Report drafts (Sections 1&2 due 11/29) • Final written report (Due 12/13) • Oral report (Given 12/13) • Poster presentation (Due 12/20)

  12. Next Time • Submit presentation area and article for approval

  13. Research Team Meetings
