Answer: special rings and bracelets
Most people don’t know sign language, which can make it difficult for deaf or hearing impaired people to communicate. A new invention, a set of rings and a bracelet are designed to bridge that gap. The configuration of the rings is detected by the bracelet, translated into spoken language and transmitted through an embedded speaker. The bracelet also has a display with voice-to-text capabilities so the wearer can see what the non-sign-language person is saying.
