Abstract
Paper prototypes have been gradually in use when designing interactions between users and artificial materials such as an application of personal digital assistant,a web service and SNS. This research examined the utility value of paper prototypes, which had been considered as simple user evaluation methods such as the thinking-aloud method or Wizard of Oz, as an extensive method of generating user's experience. We conducted lots of seminars and workshops for Japanese representative companies offering web services to acquire HCD process methods from October 2009 to February 2011. At the same time,we interviewed producers and people in UX?regularly. Based on these findings,we would like to propose the storyboarding method in which UX flows - a combination of user's activities and interactions - are represented through acting out and paper prototypes to be effective.
