Customized 3D sound for innovative interaction design

This paper considers the impact of binaural 3D audio on several kinds of applications, classified according to their degree of body immersion and their own coordinate system deviation from a physical condition. A model for sound spatialization, which includes additional features with respect to existing systems, is introduced. A significant reduction of computational costs is allowed by model parametrization according to anthropometric information of the user and audio processing through low-order filters, thus resulting affordable for several kinds of devices. According to the following examination, this approach to 3D sound rendering can grant a transversal enrichment to the CHI research purposes, in reference to content creation and adaptation, resourceful delivery and augmented media presentation. In several contexts where personalized spatial sound reproduction is a central requirement, the quality of the immersive experience could only benefit from this sort of adaptable and modular system.
