Scandinavian researchers are working on technology that could one day allow dogs to "speak." The Nordic Society for Invention and Discovery's “No More Woof” technology uses a headset with sensors to pick up the electric signals in the dog's brainwaves, which are then analyzed and deciphered as feelings and expressed as short sentences via a microphone, like, "I'm hungry, but I don't like this!" or "I'm curious, who is that?" Still to be determined is how the sensors will be attached into the dog's brain, and there are ethical and social issues as well, with a lot more work to be done on the system. Looking further into the future, the scientists would also like to be able to develop technology to let the communication go the other way, with a reverse headset that will let dogs understand what their humans are saying.
