Reproduction of High-frequency Vibration Experience by a Sensory Equivalent Conversion Method for the Standard Haptic SDK of Meta Quest 3

TL;DR

This paper introduces a method to reproduce high-frequency vibrations in VR using a sensory equivalent conversion, enhancing realism in haptic feedback on devices like Meta Quest 3.

Contribution

It presents the ISM method for converting high-frequency vibrations into perceivable low-frequency signals, validated through experiments and a practical VR demonstration.

Findings

ISM effectively reproduces high-frequency vibrations in VR.

Users perceive more realistic tactile sensations with ISM.

The method is successfully implemented on Meta Quest 3.

Abstract

In recent years, there has been a growing demand for realistic haptic experiences in VR. This study employs the Intensity Segment Modulation (ISM) method to convert high-frequency vibrations into low-frequency amplitude-modulated waves on VR devices. We verified the generation of high-immersion vibration stimuli synchronized with audio. Additionally, we compared the perception of ISM-converted vibrations between VR devices and other devices to evaluate the effectiveness of ISM in VR environments. A demonstration on the Meta Quest 3 was also developed, allowing users to experience the tactile sensation of handheld fireworks.
