  1. Adaptive Interfaces Nathan Sakunkoo

  2. Today’s Readings Ephemeral Adaptation ‘09 - Interaction Mixed-Initiative UI ’99 - Agent Recommender Systems ‘97 – Design Space

  3. Ephemeral Adaptation • Spatial Form • Examples: XP Start Menu • Lacks spatial consistency • Not so effective except in certain conditions • Graphical Form • Examples: color highlighting • Temporal Form: this paper

  4. Ephemeral Adaptation: Main Points • Good performance when prediction algorithm accuracy is high. • Not so poor performance when accuracy is low. • Pilot study with Abrupt Onset- Discouraging • Gradual onset: • Methods: 2 experiments, 48 users • Study 1 Findings: Ephemeral is faster than static menu, Ephemeral is preferred to control (esp. for high accuracy) • Study 2 Findings: Ephemeral faster than Highlight, but not preferred to Highlight – WHY?

  5. Ephemeral Adaptation: Discussions Overall Results Methods Applications

  6. Overall Average Rating – 3.96 Clarity: The structure of the paper, however, was very clear, the methodology was very transparent, and this made their findings very accessible. – Eyal Recency: CHI 2009! Wow, its good to see a 2009 paper after reading papers from the 40s and 70s. - Akshay

  7. Performance Gain Result shaving a 100ms off of a menu selection task doesn't feel that compelling – Jesse wasn't clear that the performance gains were substantive enough – Mike not sure how much speed savings is considered good enough – Sharon

  8. Preference Result • Subjective • try to please researcher • prefer fancier interface in the short-term • could be valuable to delve deeper into the specifics of what made each more satisfying • is 7 vs. 3 that significantly different from 5 vs. 4? - Patty

  9. Methods

  10. Applications In which kinds of interfaces/tasks would Ephemeral Adaptation be applicable and in which kind would it not? • Webpage – NY Times • MS Office – Menu • Everyone hates MS 2007. Does Microsoft employ similar techniques for their products? • How well do these experiments translate to real user satisfaction in software products? – Reid • Others

  11. Principles of Mixed-Initiative UI http://research.microsoft.com/en-us/um/people/horvitz/lookout_video_horvitz.wmv

  12. Summary • Mixed Initiative UI = Agent + Direct-manipulation • Interfaces that enable users and agents to collaborative effectively • 12 principles learned from LookOut • Developing significant value-added automation • Considering uncertainty about a user’s goals • … • Methods on managing uncertainties • Based on expected utilities

  13. Recommender Systems – ‘97 • Design Space • Domain Space • Social Implications • Incentives • privacy

  14. Design Space
