This paper proposes a novel concept of “stereohaptic vibration,” which employs distributed vibration to localize vibration sources outside the body. Inspired by amplitude panning, a stereophonic sound display technique, we developed a method to localize a virtual vibration source (VVS) by polarizing the perceived intensity of multiple vibration stimuli to a specific orientation. Considering the perceptual characteristics of high-frequency vibration, the perceived intensity of the VVS was allocated to multiple vibrators according to the distance and direction of the target. The velocity discrimination performance was confirmed by utilizing four stimuli around the arm and one vibration stimulus to the palm to localize the movement of a VVS throughout the arm. Discrimination experiments of the trajectory of outgoing objects with a single arm and dual arms revealed that our approach could localize in three dimensions, even outside the body. The proposed technology for localizing external virtual vibration sources is expected to enhance the virtual reality experience.

本文提出了一种新的“立体触觉振动”概念，它利用分布式振动来定位体外的振动源。受 Amplitude Panning（一种立体声声音显示技术）的启发，我们开发了一种通过将多个振动刺激的感知强度极化到特定方向来定位虚拟振动源 （VVS） 的方法。考虑到高频振动的感知特性，根据目标的距离和方向，将 VVS 的感知强度分配给多个可控震源。通过利用手臂周围的四个刺激和手掌的一个振动刺激来定位 VVS 在整个手臂上的运动，从而确认了速度鉴别性能。对单臂和双臂的传出物体轨迹的鉴别实验表明，我们的方法可以在三维空间中定位，甚至在体外。拟议的用于定位外部虚拟振动源的技术有望增强虚拟现实体验。
