Abstract
Cybersickness remains a major barrier to comfortable virtual reality (VR) use, particularly during rapid changes in motion. We present a jerk-triggered bone-conducted vibration (BCV) system that delivers brief BCV stimuli shortly after the peak of linear jerk, targeting the transition where linear acceleration begins to decrease. This timing is designed to induce an inverse coupling effect by introducing BCV as acceleration decays. We develop a low-cost hardware platform and a software pipeline that enables real-time triggering and seamless compatibility with existing SteamVR applications. To support practical deployment, we introduce a lightweight earhook mounting concept that clips directly onto a VR headset and maintains consistent contact with the mastoid without headbands, calibration, or user-specific fitting. We report engineering validation of system operation, including end-to-end triggering behavior and integration reliability, and outline a future controlled human-subject study to evaluate effectiveness for cybersickness mitigation.
