Morse code is one of the more remarkable languages that humans have ever created. Designed in 1836, shortly after the telegraph was invented, it had a huge influence on early electronic communication as well as aviation and warfare.
Today Morse has largely been replaced by bits and bytes when it comes to sending messages over great distances. But it’s still popular among amateur radio operators and people with motion disabilities. And now it’s also being used to prove that people can learn while not actively paying attention.
Researchers at the Georgia Institute of Technology have built a system that can teach people morse code while they’re concentrating on something else entirely. To do it, they modified a set of Google Glass (remember that?), which has a built-in speaker and bone-conduction transducer that simulates the experience of being tapped on the side of the head.
