Use PicoGUI with Touchscreen

Hello,

Within my current project I use a intelligent camera from Matrix- 
Vision which have a PowerPC and uses PicoGUI for the graphics.
I can use a normal mouse and a VGA screen without problems. Everything  
wokrs fine.
Does someone know if it is possible to use a USB Touchscreen with  
PicoGUI on such a device (PowerPC).

Thanks a lot for your help.
