• Commercial behavioral tests of mockups, prototypes, and products (“playtests”)
• • Typical N=2-10, targeted recruiting via friends & family, online services (mechanical Turk, Sermo). Screening and representation via pretest survey. 60-min videoconference, intro-use-discuss. Often blinded (two prototypes per session).
  • Data: spoken language, observed body language, decisions and behaviors during prototype (simulated purchase, voluntary use continuation), visible facial and body emotions
  • Results: Feature/Benefit relationships, SWOT analysis, frequency graphs of use/behaviors/themes, discussion
