7. Defining Key User Paths Paper prototyping Interactive wireframing Key user tasks Nonfunctional Functional User Scenarios Multiple scenarios Users and tasks Content layout (wireframes, storyboard)

8. Paper Prototyping Gathering usability data as early as possible Greater impact on user experience Cheaper to change early in development process Willingness to change However Difficult to convince the management Developer’s habit Example http://www.nngroup.com/reports/prototyping/video_still s.html

9. User Interaction Scenarios Stories about people and their activities Elements Setting –details that motivate/explain or starting state Actors – humans interacting Task goals – motivate actions Plans – mental activity directed at converting goal into a behavior Evaluation – mental activity directed at interpreting features of the situation Actions – observable behavior Events – external actions or reactions
