  Large screen multi touch interactive application design
  
  I am supposed to design an application for a large multitouch screen. By large, i mean newscaster large (around 55 inches and above). The application is an interactive map.  
  My questions is: which technology to develop the application in. My first idea was to make it in Adobe Flex, but then there is HTML5 too... 
  There must be some awesome Java library for touch interactions too, but then on Windows platform there must be C# library too?  
  Could someone please point me in the right direction.   
  The backend is probably going to be in Java EE. 
  Is there a specialized touch maps sdk?
  
  A:
  
  Why reinvent the wheel?
  Ventuz hands down best touch software I have used and I use it daily. It's specifically for large multi-touch presentations. 
  If you are looking to build it yourself, you will have a long long way to go. Ventuz is extremely flexible and will let you do anything you'll need to do with touch for the most part.
  (And they are based in Germany, like you)
  Here are some demos they showed last year at NAB
