Out-of-body Localization of Virtual Vibration Sources Using a Limited Numbers of Transducers on the Torso

TL;DR

This paper introduces a jacket-based stereohaptic system that localizes virtual vibration sources around the torso using limited transducers, enhancing immersive experiences in virtual environments.

Contribution

It presents a novel torso-worn device capable of out-of-body localization of virtual vibrations with fewer transducers than traditional methods.

Findings

Successful localization of virtual sounds around the torso

Enhanced immersive experience with limited transducers

Demonstration of virtual footsteps and roars in a realistic setting

Abstract

Stereohaptic vibration is an innovative vibrotactile technology that extends the conventional tactile localization to the surrounding space, representing a virtual vibration source in the external environment. Previously, we have developed displays on the forearms and soles. Today, we present a demonstration of a new jacket-type device, which enables localization at any position around the body by arranging multiple vibrators along the torso centered on the midline. In our demonstration, you can experience the footsteps and roars of a inosaur walking around you, and it provides an experience that is as if you are in a fantasy movie.
