Current work does much better than that. Continuous recognition has been 
around since 1996, and some Chinese research groups have extended the 
vocabulary to more than 1,000 signs. However, even this work still basically 
views signs as a string of gestures, without inflection or other grammatical 
processes, so there still remains much work to be done.

Facial expression tracking and recognition (which is my current research area) 
is also a thorny issue.

Let me know if you would like me to dig up some references.
