Abstract
Digital  music  performance  require  high  degree  of interaction using natural, intuitive input controllers that provide fast feedback on user¡¯s action. One of the primary considerations of  professional  artists  is  a  powerful  and  creative  tool  that minimizes the number of steps required for the speed-demanding processes. Most  of  the musical performance  applications, which are  designed  for  mobile  devices,  use  touch-screen  or accelerometer as interaction modalities. In this work, we present a  novel  interface  for musical  performance  that  is  based  on  the magnetic  field  sensor  embedded  in  recent  mobile  devices.  The proposed  method,  at  this  point,  promises  a  new independent ground for  inputting momentary data during music composition and manipulation process. Giving the opportunity to freely, fully and  quickly  utilize  the  surrounding  3D  space,  it possesses the potential  to  bring  a  wide-spectrum  of  unique  options  for production and performance process of music.
