If you enjoyed (or if you missed) Selma Zafar's hugley popular Mobile UI seminars at Wave Front in Vancouver, you'll be pleased to know what we've posted the slides from the session on Slideshare.
In her presentation, Selma covered the basics of user-centred design, interaction design principles, and usability testing as they pertain to mobile devices.
