Questions are almost entirely made with the face (by raising the eyebrows) as one example, which is ASL specific.
I think technology might someday be able to understand ASL and other signed languages (every region/area has their own signed language, generally). But it will be long after computers can easily understand spoken/written languages, which they can only sort of do now and even then very rudimentary currently.
Languages are very complex, and signed languages are no different, but add extra complexity, because you have to also handle facial expressions and hand/arm AND body movements (the whole body moves in ASL to delineate different contexts as another example.)
I for instance just carry around an iPad with a text app (like Sorenson's Buzzcards) which make communicating with hearing people way easier, and save paper.
