Background: A performer in Las Vegas would like to add more real time interactivity to his live show. He wants to have the audience ask him questions, and while answering them, select appropriate video footage to show to the audience. The interface has to be easy enough to use so that he’s not distracted from his real job — performing. Typing into the app during a performance would not be acceptable. He needs a gesture-based interface.

Personas: Personas inform user interface design by designing for specific user needs rather than designing for vague generalities. Personas help create solid design decisions because they can help the user experience designer step outside of his or her own goals and desires and create more empathy for real users of the application.

In this particular instance, the primary persona isn’t a real persona but the others are.

The interface for the primary persona is an iPad application that talks to a server.
