Integrating physically based sound
models in a multimodal rendering
architecture
By Federico Avanzini and Paolo Crosato
..........................................................................
This paper presents a multimodal rendering architecture that integrates physically based
sound models with haptic and visual rendering. The proposed sound modeling approach is
compared to other existing techniques. An example of implementation of the architecture is
presented, that realizes bimodal (auditory and haptic) rendering of contact stiffness. It is
shown that the proposed rendering scheme allows tight synchronization of the two
modalities, as well as a high degree of interactivity and responsiveness of the sound models
to gestures and actions of a user. Finally, an experiment on the relative contributions of
haptic and auditory information to bimodal judgments of contact stiffness is presented.
Experimental results support the effectiveness of auditory feedback in modulating haptic
perception of stiffness. Copyright © 2006 John Wiley & Sons, Ltd.
