Its inevitable that rich internet application will be developed for all the multi touch devices with various form factors. In this presentation I will demonstrate an approach to use the physical size of the finger tip as the center point for design. From the perspective of the finger tip all devices are the same, basically it has a screen and the finger doesn't change size regardless of the pixels per inch of the screen. I will be showcasing Flex 4 code that makes development for RIA's across the various form factors possible.
Clipping is a handy way to collect important slides you want to go back to later.
