Do Tablet PCs support multi-touch (with more than 1 or 2 fingers?)
I'm aware of only two commercially-available multi-touch
control surfaces:The Fingerworks products (they have a free, pretty comprehensive SDK
as well): www.fingerworks.comThe now-defunct MTC express: www.tactex.com.
A friend of mine, Bob Huott, has worked extensively with tactex. He is
basically abandoning it because of its limitations. It does do
multi-touch very well, but it has a low refresh rate, and you need
roughly 2cm between touches in order for them to be detected as
individual events rather than one. Also, it takes a decent amount of
pressure to actuate it, but it is pressure sensitive as well.
As for building a Lemur with Pd and a tablet, there is another
limitation in that most OS's only support one pointer, so even if the
screen could handle multi-touch, the OS probably could not. But it
would be cool...

exclusive property, it is the action of the thinking power called an
idea, which an individual may exclusively possess as long as he keeps
it to himself; but the moment it is divulged, it forces itself into the
possession of everyone, and the receiver cannot dispossess himself of
it."
