My talk on UI Design at Adobe Flash Platform Summit 2011 in Bangalore. With great power comes great responsibility. This dialog from Spiderman holds true in the context of what developers can do to UI/FE today with the power of RIA technologies like Flex/Air. The User Interface or the Front End realm has been ever evolving. With each step that technology takes towards sexier and delightful experiences, the challenges to create simplistic good user interface experiences seem to be growing exponentially. This session will start by covering the basics of good and bad design experiences and cover how important it is to understand good design principles in the context of RIA technologies like Flex/Air.
