An Audio-Haptic Interface Concept Based on Depth Information

By D. Devallez, D. Rocchesso and F. Fontana


We present an interaction tool based on rendering distance cues for ordering sound sources in depth. The user interface consists of a linear position tactile sensor made by conductive material. The touch position is mapped onto the listening position on a rectangular virtual membrane, modeled by a bidimensional Digital Waveguide Mesh and providing distance cues. Spatialization of sound sources in depth allows a hierarchical display of multiple audio streams, as in auditory menus. Besides, the similar geometries of the haptic interface and the virtual auditory environment allow a direct mapping between the touch position and the listening position, providing an intuitive and continuous interaction tool for auditory navigation
