re signing avatars

recognition (à la the Haskins and Bell Labs research in the 1940s and
1950s).

For anyone who's interested, Philippe Dreuw at RWTH Aachen University,
Aachen, Germany, is working on gesture recognition and I have done some
collaborative work with him for translating in the direction of SLs
(American and Irish) to Engllish. The results from the ASL data so far have
been somewhat promising, although of course there is still a lot of progress
for it to be made usable in the mainstream. Machine translation is my area,
not recognition, so I'm not in a position to describe this much further but
you can find some more information in the paper "Hand in Hand: Automatic
Sign Language to English Translation" in the Proceedings of Theoretical and
Methodological Issues in Machine Translation (TMI-07).
