This paper is a theoretical dissertation on the role of the matter and its representations through dynamics in the organization of the multisensory space. We assume that the mechanical matter, which originally produces the multisensory-handled events, is an invariant identified from the spatio-temporal correlation between visual, auditory and tactilo-proprio-kinesthetic perceptions. We illustrate this assumption by several examples using virtual objects modeled by means of physically-based formalism, able to produce dynamically plausible and consistent multisensory events. We then examine frontiers between ambiguous notions as: geometry vs. dynamics in visual believability, optical matter vs. mechanical matter in contour identification, interaction vs. morphology or topology vs. force in complex manipulations. We conclude that, a challenge to enhance the presence of virtual objects is to be able to instill in their models a just sufficient clue of evoked materiality using minimal physically-based representations.
