One of the weaknesses of the different translation apps and services is that they are for spoken languages. Sign languages are a major language that they can’t translate. That may be changing in the future after two undergraduate students at the University of Washington invented SignAloud gloves, which are designed to translate American Sign Language into speech or text. Of course, American Sign Language is not universal, and it will probably take a while to work out the many different forms of ASL alone. But like with all new technology, the first versions always evolve into better and better tools. Hopefully this will continue beyond the experimental phase.
