Abstract

This paper presents a novel approach to simulating liquid interactions for haptic bilateral teleoperation without complex fluid dynamics simulations. We propose a model combining a simplified drag equation with a "position tail" mechanism to approximate force feedback for viscous and turbulent liquids. The model was evaluated through theoretical analysis, manual testing, and a user study. Results of the latter demonstrate the ability to convincingly simulate different liquid types, with participants correctly identifying viscous and turbulent liquid types. The study also revealed that visual feedback delays up to 125 ms did not significantly impact user experience. While promising, the system remains sensitive to noisy input data. This research contributes to the development of efficient and believable haptic simulations for teleoperation, paving the way for future developments.
