Rachel Hinman has published a mammoth (and comprehensive) presentation about the elements of mobile user experience.

“Recent innovations are causing an inflection point in the mobile UX landscape, providing the opportunity to invent new and more human ways for people to interact with information. But where do designers who are steeped in the static desktop-computing paradigm begin? The purpose of this talk is to help UX designers and other UX professionals answer that very question. I’ll share the three most important mobile design principles to consider when creating a mobile user experience, some mobile design exercises, and mobile prototyping tips.”
