ABSTRACT The proliferation of interactive technologies expands the palette of the architect, prompting a re-examination of notions of materiality in architecture. This article explores how the introduction of computational processes that accelerate, amplify or animate conventional mechanisms of time and space might alter the relationship between human perception and matter. We present a spatial paradigm for the materiality of interaction in architectural space and demonstrate it in a recent installation work, Trivet Fields , which employs a heterogeneous model of interactivity to articulate spatial materiality.
