HydroRing: Supporting Mixed Reality Haptics Using Liquid Flow
summary
A finger-worn latex tube routes water from hot and cold reservoirs through peristaltic pumps and a terminal solenoid valve to render pressure, vibration and temperature directly to the fingertip. The prototype produces 0.1–2.6 N, 1–50 Hz vibration and about 2–50 °C, with latency ~1–2 s for pressure/vibration and ~5 s for temperature. Two user studies (n=12 each) show reliable discrimination across 3–5 levels and only a 3.7% drop in perception when worn. mixed-reality haptics passive and active modes
