Someone has invented signing gloves - again. While I understand the thought process behind sharing news such as this - these gloves really aren't as useful as they would seem.
There are a lot of non-manual markers used in ASL that can't be relayed on the hands. (Facial expressions, queries, emotion, etc). It would take less time learning how to finger spell, at the very least to get your point across than it would to develop & market these things.
