I'd been kindly invited by Rodrigo Rocha to teach some thoughts about Usability + Mobile to his students. The intention of this presentation is to provide an overview, some tools and references, so the students can apply them right away and look for more. The intention is NOT to explain everything - this would be a task for several weeks. I hope it is useful for you too. (at Federal University of Bahia, Salvador - Brasil, 30/01/2012)

9. Utility = whether it provides the features you need
Usability = how easy & pleasant these features are to use
Useful = Utility + Usability
