body: <p>I'm using bluetooth surface published in <a href="http://code.msdn.microsoft.com/Surface-Bluetooth-Connect-dbe7e0e8" rel="nofollow">http://code.msdn.microsoft.com/Surface-Bluetooth-Connect-dbe7e0e8</a> I add the kinect in this wpf application. But i need multitouch function to zoom in and zoom out the scatterviewitem picture. So can anyone give me idea about how can i achieve multitouch in this application.
  And i also try using kinect gesture to zoomin the scatterview, but it still have a problem how to select the scatterviewitem in scatterview and zoom it.</p>
