Connecting virtual sound and physical space in audio-augmented environments
This paper describes strategies to create multimodal coherences between sound and space in Audio-Augmented Environments. Visitors to AAEs wear motion-tracked wireless headphones displaying a location-aware, adaptive audio presentation augmenting the physical space with virtual sound-scenes. The work underlying this paper was done by the author during the course of the LISTEN project at Fraunhofer IMK. In the first half, the concept of the `perceptual device' is introduced, which allows attaching audio content to a physical space. In the second part this is supported by practical examples from the publicly accessible AAE ``Macke Labor''. The ``Macke Labor'' was installed at the Kunstmuseum Bonn, opening in October 15th 2003. It was developed by the author with an interdisciplinary team of collaborators. The paper is rounded off with the description of the sonification technique used in the evaluation of the recorded tracking and event data of the ``Macke Labor''.
