Sign Language gloves are an interesting idea, but they don't work. Sign language relies heavily on facial expressions and body language beyond the hands.For clarity, could you give an example of a sign that changes to mean a different word or phrase depending on facial expression?

People often aren't keen on solutions that are either still nascent or that they haven't given a chance yet. My mom wasn't keen on navigating with a GPS until she had one in her car and it changed her life. Not being keen is not on its own a great reason to dismiss a technology. The reason matters.
IMO a more meaningful statement might be to say that the obvious alternative is simply a small keyboard, which already exists.
