There were lots of new feature announcements at Adobe MAX this year but one of the most exciting was support for multi-touch in Flash Player 10.1. This along with the likes of accelerometer are paving the way for a massive push onto smartphones. You won't be able to buy a smartphone next year that doesn't come with a Flash Player... okay, maybe just one.
During the keynote Adobe CTO Kevin Lynch demonstrated multi-touch in AIR 2.0. What caught my eye was the app was using multi-touch gestures to control calendaring. Swipe to flick from month to month and pinch to zoom into weeks and days. The company behind the demo are Cynergy Ssystems who are doing some great work with UX in web applications. If you want more information about the project it's worth reading the blog posts from Dave Wolf and Andrew Trice.
