ALTAR/TABLE: A PLATFORM FOR PLAUSIBLE AUDITORY AUGMENTATION
Abstract | With auditory augmentation, we seek to project digital information into the physical world by modulating irrelevant aspects of everyday auditory feedback, while at the same time preserving relevant ones. In order to stay plausible, we employ the metaphor of the physical object itself being modulated by the data. By mapping information to physical parameters rather than to arbitrary sound parameters, even untrained users can draw on prior knowledge. Here we present AltAR/table, a hard- and software platform for plausible auditory augmentation of flat surfaces. It renders accurate simulations of rectangular plates by using a detailed modal synthesis model. The structure-borne sound is recorded, fed through a physical sound model, and played back though the same object in real time. The implementation solves the basic problems of equalization, active feedback control, spatialization, hand tracking, and low-latency signal processing. AltAR/table provides the technical foundations of object-centered auditory augmentations, for embedding sonifications into everyday objects such as tables, walls, or floors. |
