making interactive app quickly with minimal code

simulate interactive behaviour with human operators

  • make interactive app without much code
    • front end interface
    • remote wizard controls user interface
    • makes sense with is faster/cheaper/easier than making the real thing
  • get feedback from users people
    • hi-fi users think its more real
    • low-fi: more license to suggest changes

1 making wizard protoypes

  • find scenarios to protoypes
  • create UI skeleton
  • develop hooks for wizard input
  • decide where and how the wizard will provide input
    • remember not to fake stuff that it not feasible in real life
  • rehearse wizard rile with colleague

2 running wizard protoypes

  • practivce with friend

  • recruit users

  • two roles:

    • facilitator ⇒ pprovides tasks and takes notes
    • wizard ⇒ operaties interface
  • user feedback

    • think aloud
    • retrospective
    • heuristic evaluation
  • debrief users

3 used throughout development

user can do less and less and the prototyp comes closer to realisation

4 advatages

  • fast
  • variable
  • more real than papar prototypes
  • finds bugs and pronlems with design
  • places user at center
  • can envision challenging to built application
  • ability to look foward and “use” tech that isn’t created yet

5 Disadvatages

  • simulations may misrepresent otherwire imperfect tech
  • mya simulate techs that not not exist (and mnay never)
  • require training and can be inconsistent
  • playing the wizard can be exhausting
  • some features are difficult to simulate
  • may not be appropriate
