This document outlines an agenda for a workshop on mobile prototyping essentials. The morning session will discuss what makes mobile UX different from web design and include exercises on identifying mobile needs, ideating concepts, and creating prototypes. The afternoon session focuses on mobile prototyping and includes exercises on storyboarding, translating graphical interfaces to natural user interfaces, and creating in-screen prototypes. Key principles discussed for mobile design include designing experiences that are uniquely mobile, sympathetic to user context, and allow the interface to "speak its power" through intuitive interaction.
