Hmm, if I see this correctly than this doesn't generate any (or at
least not enough) entropy and thus can only be used for authentication
and not for encryption, right? The same would probably be true for
voice recognition.

The finger-gesture thing (like libstroke) on the other hand could be
used for at least enough keying material to authenticate to the SIM.
(E.g. it is possible to replace the PIN with a gesture. Which would be
a neat feature in itself.)
