GPU-Accelerated Subsystem-Based ADMM for Large-Scale Interactive Simulation

Harim Ji, Hyun‐Su Kim, Jeong Min Lee, Somang Lee et autres

In this paper, we implement the GPU-accelerated subsystem-based Alternating Direction Method of Multipliers (SubADMM) for interactive simulation. The challenging objective for interactive simulations is to deliver realistic results under tight performance, even for large-scale scenarios. We aim to achieve this by exploiting …

Symmetry-Based Modeling and Hybrid Orientation-Force Control of Wearable Cutaneous Haptic Device

Somang Lee, Hyun‐Su Kim, Dongjun Lee

We propose novel symmetry-based modeling and hybrid orientation-force control frameworks for cutaneous haptic device (CHD) to generate precise three degree-of-freedom (DoF) contact force on the fingertip robustly against user variability. The CHD hardware is designed in a form of an underactuated cable-driven …

Wearable Haptic Device for Stiffness Rendering of Virtual Objects in Augmented Reality

Yongseok Lee, Somang Lee, Dongjun Lee

We propose a novel wearable haptic device that can provide kinesthetic haptic feedback for stiffness rendering of virtual objects in augmented reality (AR). Rendering stiffness of objects using haptic feedback is crucial for realistic finger-based object manipulation, yet challenging particularly in AR …
