A team of Australian researchers is tapping into the nerves and bodies of volunteers to create a raw musical performance driven purely by emotions. In a world first, the data is fed into special software, which will create music that will be played by small robots. The research team comprises a neurophysiologist, a roboticist and an artist.
This sound is of electrical signals and these signals are taken to be signs of emotion.
I find this interesting. It is as if those feelings we feel privately are externalized to others as sound.
Elsewhere, Professor Vaughan Macefield, one of the researchers, has some interesting things to say about pain.
