As part of an experimental setup, audiovisual recordings of ground surface textures were carried out in Vienna’s St. Marx district. The aim was to translate inscribed and divergent patterns of use into an installation that makes them perceptible through concrete listening and tactile seeing. The area was explored using the method of a soundwalk along predetermined routes. Material was gathered with a mobile object specifically designed for the needs of the experiment. This interface—its form derived from a wheeled suitcase, or “trolley”—serves as a mobile tripod adapted to the demands of an urban–industrial environment.
The findings from these walks were presented as an installation, in which the recorded materials are displayed in a comparative format. The interface was equipped with a portable screen and a mobile loudspeaker system, enabling the audiovisual projection of the collected materials and their reception while walking. A topographical representation documents the gathered subjective impressions, conveying insights into the qualities of the ground surfaces within the study area.
