Fingernail-Based Tangential Force Simulation for Enhanced Dexterous Manipulation in Virtual Reality

Abstract: This study introduces a novel haptic device for enhancing dexterous manipulation in virtual reality. By stimulating mechanoreceptors on both sides of the fingernail, our lightweight system simulates tangential force sensations. We employ mechanical stimulation for more natural tactile feedback. A preliminary "balancing grasp challenge" experiment shows that users make more frequent micro-adjustments with our device, indicating improved precision. This research aims to advance haptic feedback in VR, potentially leading to more immersive and realistic virtual interactions.
