Google have introduced a new feature into Hangouts for the hearing impaired, where the Mountain View-based search giant have added in a Sign Language Interpreter app for Google+ Hangouts. This web component allows users to invite an interpreter in who stays in the background while they verbalize hand gestures.

Google didn't stop there, either, as they've also started helping reduce dependancies on the mouse for those who don't want to, or can't use one during chat. There are now keyboard shortcuts which can start or stop chats, disable the camera and other basic tasks that you'd otherwise need a mouse action.
