Accelerating the Physical Experience of Immersive and Penetrating Music Using Vibration-Motor Array in a Wearable Belt Set

Abstract

In this research, we aim to create a heightened and physical musical experience by combining electronic sound and time-lagged multiple vibrations that surround the user's neck, chest, and back. The purpose of the research is to elevate an immersive and extended experiences of music as though the sound source had a physical presence. We developed a wearable interface of a vibration-motor array with separately controlled multiple vibration motors to simulate both strong bass sounds and movement of the physical presence of the sound source. The control of intensity and the time differences among the motors produce not only the illusion of spatial presence but also the physical penetration of the ongoing sound. The results of the evaluations showed the effects of 1) the combination of vibration and sound in the musical experience and 2) time differences of the starting timings between the front and back vibrations when creating the illusion of physical penetration as though the sound had a physical presence.
