You can tell a lot about a human by how it wags it's tail. Yes, you read that right, and it wasn't a typo. Neurowear's brain controlled tail has made it so tails aren't just for the dogs anymore. The tail uses a neural application to read your "mood" and then tags it to your location. From there, you can share your "mood" socially and then search for places that other people found relaxing, scary, shocking or romantic. While it's just a concept video for now, Japanese company Neurowear wants to make this a reality.
