| contents | Haptic feedback enhances immersion in virtual environments by allowing users to physically interact with simulated objects. Supporting accurate force responses in multiphysics systems is challenging because physically based simulation of fluid, rigid, and deformable materials is computationally demanding, especially when interaction must occur in real time. We present a unified framework for real-time, bidirectional haptic interaction with rigid bodies, deformable objects, and Lagrangian fluids in virtual reality (VR). Our approach integrates Smoothed Particle Hydrodynamics (SPH) with two-way force coupling and feedback smoothing to maintain stability and produce physically meaningful tactile responses. This enables users to manipulate objects immersed in fluid and feel reaction forces consistent with fluid-structure behavior. We demonstrate the capabilities of our framework through interactive VR scenarios involving fluid stirring, soft tissue manipulation, and rigid-body interaction. The proposed system advances haptic-enabled multiphysics simulation by unifying fluid, soft-body, and rigid-body dynamics into a single platform suitable for immersive educational applications. |
