“These three levels translate into three different kinds of design. Visceral design refers primarily to that initial impact, to its appearance. Behavioral design is about look and feel—the total experience of using a product. And reflection is about ones thoughts afterwards, how it makes one feel, the image it portrays, the message it tells others about the owner's taste. ” - Don Norman on Emotional Design http: //www. jnd. org/dn. mss/emotional_desig. html

Designing Interview Questions • Ask open-ended questions: “How do you feel about” or “Why do you” not “Do you like” (“yes”) • Allow participants time/space to talk (wait if necessary) • Ask follow ups to probe deeper: “You said you would never buy [x]. Why? ” • Take notes (even better: video/audio)

Cellphone Exerise • Construct a set of questions that get at a person’s Visceral, Behavioral, and Reflective impressions of their cellphone. • Trade one member (who has a cellphone) with another team • Use your questions to interview that other team’s member about their cellphone • Take notes and discuss

Your Homework • Team (as a group) comes up with a list of prompts/questions to get at Visceral, Behavioral, and Reflective qualities of a person’s water bottle • Each team member locates two people to interview using those questions • Takes notes than shares with the team
