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

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?

• 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.

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

Methods

Focused, sounded, and thorough Missing broader issues - Kelly
Controlled experiment Want to see Realistic settings - Eyal

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
