I think something that helps deaf people to "hear" what people are saying could definitely work. I'm not super sure on this, but from what I've researched there are glasses that caption what other people are saying. I was thinking something like that could work, or another idea I had was that the gloves detect what is being said, and turns that into a series of pulses or some sort of sensory input onto the fingertips, kind of like reading braille. The problem with that idea though is that the user would have to know braille, so it might not work super well.
