Decisions and Choices

• Machine takes over your decision making!

• At the very least filters.

• What information do you use to make decisions?

WWWWWW

Interactive Segment

• Split into groups of 3-5 people.• Spend a few minutes discussing:What aspects of me help answer the question

“What should I do next?”

• As weird and unexpected as you like!• I will ask you for your outcomes after.

Results

What aspects of me help answer the question “What should I do next?”

Hugh and I thought...

• Knowledge• Interests• Preferences• Goals – e.g. I want a 2.1• Needs• Tactics – e.g. better at exams than coursework• Means – e.g. bank balance• Ability – opposite of disability

What should I do next?

• Educational system influenced by StumbleUpon?

• Rate on more than Like or Dislike – Can/can’t afford it.– Do/don’t have time.– Does/doesn’t meet my goals.

• Integrated Procrastination™

Summary

• Adaptivity involves personalising experiences for a particular user.

• This involves making decisions on the user’s behalf.

• What aspects of the user are used in decision making?

Discussion

• Questions!

• Any more personal aspects that affect decisions?

• Do you like the idea of a StumbleUpon-style activity planner?
