Further investigating i just read:
https://www.kernel.org/doc/Documentation/input/multi-touch-protocol.txt
Which is a good read about the status of multitouch in the Kernel, moreover
it explains the type of objects to be reported which are divided non
identifiable and identifiable objects.

Edward,
I strongly agree with your analysis. Any generalized touch (marker, finger,
pen) has a general elliptic shape defined by a rectangle, when a device
does not support that info, touches are just degenerate squares 0 by 0 and
zero area. But richer devices might provide blob rect and blob angl

Hi, Ariel.

Hi,
Research is strong on natural user interfaces, and now market is stronger
than ever and growing. I was working on the TUIO QPA and found a couple of
bugs, which I already pushed patches [1] [2] which I hope make it to 5.6.x.
OTOH, to further enhance touch interfaces I want to bring the discus
