HydroHaptics: High-Fidelity Force-Feedback on Soft Deformable Interfaces using Hydrostatic Transm...
summary
HydroHaptics uses hydrostatic transmission (water-filled hydraulic cells and tubing) driven by a brushless DC motor and lead screw to deliver bidirectional force feedback on soft interfaces, achieving a 10 N in 100 ms transition and rendering 1 N at 10 Hz. System senses displacement to 0.18 mm and pressure to 0.23 kPa, yields RMS force error 0.17 N, and classifies gestures at 89.1% (N=18); prototypes include a cushion, deformable joystick, backpack straps, and a sculpting mouse.
