Eye.Breathe.Music: creating music through minimal movement

Eye.Breathe.Music is a musical interface that can be controlled by movement of the pupils and breath pressure. The interface uses a pressure sensor to measure breath intensity; a camera to track eye movement and a display to provide the user with interactive feedback. This paper discusses the background research into the instrument, how this was used to design and construct the system, an evaluation of the resulted prototype, future development and possible applications.
