To properly translate ASL, you need to pick up a significant amount of grammar from the face (called non-manual markers) as well as body position, 3d capture of spatial relationships between signs as they are made, and other features which would be inaccessible to these sensors.<p>And then there&#x27;s the fact that ASL isn&#x27;t serialized English (it&#x27;s actually unrelated to English at all, and has its roots in the French Sign Language).  There&#x27;s no one-to-one mapping between ASL signs and English words, just as there&#x27;s no one-to-one mapping between Chinese and French, or any two languages.  And ASL has grammar features not seen in any spoken language, to complicate things further.<p>These sensors could perhaps be used to translate other sign languages, but I&#x27;m really skeptical.
