Hi,

You mean with a standard Linux build?

We are using Sharp PN-K322BH for direct interaction.
We also use two 3M models (M2167PW and M2256PW) when application is set with 
indirect interaction. But in this case we implemented our own USB drivers (3M 
has their USB protocol documented) and we send Mouse and keyboard events to 
main screen.

With direct interaction we should use JavaFX Events...

With the latest code you should be getting notification of multitouch gestures 
as well as raw multitouch events. These events use JavaFX's built-in gesture 
recognizer for embedded platforms.

Out of curiosity, what touch screen are you using?

Thanks,
Daniel
