On Friday September 3rd 2010 at 13:00h and in room 55.410, Miha Ciglar, from the Institute of Sonic Arts Research in Ljubljana, Slovenia, will give a seminar on: "An ultrasound based instrument generating audible and tactile sound".

 Abstract: The presentation will give an overview of the Institute for Sonic Arts Research (IRZU) from Ljubljana, Slovenia and its projects. A particular focus will be put on one of the most recently developed interface prototypes - a “hands free” instrument, utilizing a non-contact tactile feedback method based on airborne ultrasound. The three main elements/components of the interface that will be discussed are: 1. Generation of audible sound by self-demodulation of an ultrasound signal during its propagation through air; 2.The condensation of the ultrasound energy in one spatial point generating a precise tactile reproduction of the audible sound (its temporal and harmonic texture); and 3. The feed-forward method enabling a real-time intervention of the musician, by shaping the tactile (ultra)sound directly with his hands.

In addition to the presentation, the interface functionality will also be practically demonstrated,
