It looks a bit like the memory eraser used in Men in Black, but the Sign Language Interpreter is nothing to fear. It's a concept by designer Mac Funamizu, and the locket-sized device would, in a perfect world, be able to read hand gestures and then speak the signed words out loud. In case you needed to do the reverse — convert your speech into hand signals — there's already a real world gadget for that.
The Sign Language Interpreter consists of a camera to pick up gestures, and a clever speaker that has its volume controlled by how far you open it up out of the bottom of the unit. Check out the gallery below for more of the Sign Language Interpreter.
