2. 2 Adaptive User Interfaces  Earliest study by Greenberg & Witten, 1985

3. 3 Consistency in the User Interface  Grudin, 1989 – The Case Against UI Consistency  Internal Consistency  External Consistency  Correspondence

4. 4 Model-Based User Interfaces  Pioneered in the late 80s & early 90s by Foley & co, Myers & co, and others  Challenge: homogoneity of desktop eroded most of the benefits  New opportunity! Heterogenaity of ubicomp… also implies new challenges

5. 5 Design for Multiple Devices  Computing world increasingly diverse  Hard to design for variety of devices  Use automatically generated UIs  results in UIs poorly optimized for device  only used as last resort by end-users MOTIVATION

6. 6 Study of Cross-Device Designers  Interviewed 9 UI designers  UIs targeted at desktop and PDAs and/or mobile phones  usually, mobile UI was a subset of desktop UI  Tools and process  similar to web design in many respects  less sketching, more Visio  can quickly type out whole screens MOTIVATION

7. 7 Study of Cross-Device Designers  Consistency across devices is major burden  led to teams being organized by project, not device  Recurring patterns often observed  3 groups incorporated these into mobile phone UI style guides  Hard to deal with so many devices  must test UI with each device  less time for early-stage prototyping and evaluation MOTIVATION

8. 8 Design Patterns  Communicate design problems & solutions  how to create navigation bars for finding relevant content  how to create a shopping cart that supports check out  how to make e- commerce sites where people return & buy…

9. 9 Navigation Bar  Problem: Customers need a structured, organized way of finding the most important parts of your Web site  Example  Solution PATTERNS First-level navigation Second-level navigation
