Meta Quest 3 — Hand Tracking & Controller Experiments
First prototype — ghost hand with sphere joints, offset right hand.
handsGhost right hand with mesh model, head-relative offset, adjustable via thumbstick. Real hand show/hide toggle.
handsFull experiment: 10 blocks with random offsets (±15cm), 10 target-touch trials per block. Accuracy measurement window, CSV export, and in-VR plots with whiskers.
hands experimentMovement speed limit on both hands. Ghost freezes blue when too fast. Stereo sawtooth buzz audio cue. Joystick-adjustable limit.
hands audioSame speed constraint with relaxing warm sine chord audio — fundamental + octave + fifth. Gentle pitch rise as speed increases. Stereo panning per hand.
hands audioSame speed constraint applied to Quest controllers. Ghost controller shape freezes at last position. No hand tracking required.
controllers audioCalming hand-tracking game. Touch floating shapes to burst them into colorful confetti with pleasant chime sounds. Pentatonic scale audio, gentle pulsing shapes.
hands audio gameQuest 3 passthrough MR. Detects real-world planes and meshes via WebXR Scene API. Drop colorful boxes with triggers — they fall and land on real furniture and floors. Haptic feedback.
controllers Quest 3 MRQuest 3 body tracking (experimental). Renders full body mesh with skin capsules, skeleton joints, and bone connections for all 84 joints including fingers. Requires chrome://flags → WebXR Experiments.
body Quest 3 experimentalQuest 3 body tracking driving a VRM avatar via @pixiv/three-vrm. Humanoid bone retargeting from WebXR body joints. Mirror included. Replace the VRM URL with your own VRoid Hub avatar. Requires chrome://flags → WebXR Experiments.
body VRM Quest 3 experimentalImproved retargeting: non-uniform scale matching both height (Y) and arm span (X/Z) to the real person's T-pose. Finger articulation, sky, real floor, dynamic grounding.
body VRM Quest 3 experimentalController-only speed constraint for Quest 2. Warm sine chord audio with stereo panning. No hand tracking required.
controllers audio Quest 2Play a theremin with your hands. Right hand height controls pitch (110–880 Hz), left hand height controls volume. Web Audio API oscillator with reverb and vibrato. Mirror included.
hands audio music200 000 particles rain down on a mirror of your body 2 m ahead. Capsule collision against all major limb segments — body shape emerges from impact patterns. Step back and watch. Requires chrome://flags → WebXR Experiments.
body Quest 3 experimentalPinch to shoot! Destroy floating targets with hand-tracked projectiles. Stereo shoot sounds, impact thuds, and score chimes via Web Audio API.
