In order to interact with PDa using gesture recognition, you have to
install the xstroke program on the device (this should be part of
openembedded, and therefor of familiar and openzaurus).

For more information about xstroke see http://www.xstroke.org

You can define your own alphabet and therefore map different
gestures to keys. The keys are then recognized by using Pd's key object.

For the serial input you can use the comport external. The rest should be
the same as on "normal" computers, that is you need a useful device
that delivers the data. I am not really a specialist in those, though,
but I would like to build a "key-jacket" for PDa, something similar
to the "dataegg" http://www.e2solutions.com/dataegg/index.html
for the left hand.
