一 Thinking aloud
—— Form and Feedback Co-evolve from informal to formal
场景->TRY->高保真
Story Board: setting + sequence + satisfaction->Paper Prototyping:Get creative with materials->Digital Mock-ups
二 Faking it!
——Implementation not matters, AI included.
Wizard of Oz : Something like Turing Tes t: facilicator(interactive) & wizard(manipulate)
Video Prototyping: Focus on message more than production values
三 Creating and Comparing Alternatives
—— Parallel >> Serial : separating ego from artifact(avoid functional fixation) and comparisons aids learning(~3x)
Sharing: alternatives as a vocabulary
