The prototype of a wearable shoe-based interface is presented, which provides the user with auditory cues of ground. Data supplied by sensors embedded in the shoes drive a set of physics-based synthesis models running on a laptop, whose audio output is sent to a pair of shoe-mounted loudspeakers. By informing the synthesis models with ecological properties of grounds, neutral floors can be
interactively augmented so as to react like they were made of a different
material.
