summary

An ungrounded device actively shifts a 500 g internal mass via a motorized 3-DOF gantry (four motors, PID control, Bluetooth microcontroller, slip ring) to emulate fluid center-of-gravity changes computed in Unity with NVIDIA Flex and tracked with HTC Vive tracking. A user study (24 participants, 7 actions, 2 simulated viscosities) shows SWISH outperforms a fixed-weight replica and approaches a real-water bucket (especially at higher viscosity). Limitations: noise, tethering, bulky size, occasional rotational tracking error and latency; future work targets quieter motors, smaller form factors, multisensory cues.
