Brain-to-brain communication used to send greetings between people. A human test subject in India has emailed the messages hola and ciao to three other people in France. Doesnt sound too impressive? Well, in this case the words were composed and interpreted using only the brain ... along with some high-tech help. At a lab in India, the sender started by translating the letters of the words into a type of binary code, and then entering that code into a computer. The latter was achieved using a brain-computer interface in which an EEG cap measured the electrical activity in their brain. It did so as they performed an exercise in which they had to select the 1s and 0s that made up the binary-coded letters – in their proper sequence – using a video game-like computer screen interface that responded to changes in their EEG readings as they thought of moving either their hands or their feet (but didnt actually move them).
