POLYUS: Johannes Wernicke (AT) – Interface Culture, Kunstuniversität Linz


Polyus is an omnidirectional speaker which allows multiple listeners to perceive different sounds from the same source simultaneously. Using Polyus, sounds can be positioned into specific areas of a room, which will be only perceived by the listener in relation to how he/she is located in the area where a sound was assigned to. The system consists of three core components: The Acouspade, a directional speaker, able to focus sound into a narrow beam, a reflector redirecting the sound while spinning at a high velocity and a LIDAR (light detection and ranging) sensor tracking the visitor’s position. It allows the creation of nonlinear, spatial compositions through which the audience can move, as opposed to perceiving them on a timeline. The system should also test our ability to orient ourselves using our hearing.
