Enlarging Error Detection Threshold of IMU-based Hand Tracking in VR with Haptic Feedback

This dataset contains raw and processed data from four psychophysical experiments on finger‑tracking error perception in VR. It includes: • Exp 1–2: MOCAP‑based trials with synthetic 3‑D perturbations (no haptics vs. true/false cutaneous feedback) • Exp 3–4: Wearable IMU‑based trials with realistic sensor noise and drift (no haptics vs. true/false feedback) Each .txt file records trial‑by‑trial responses, timing, applied error magnitudes, 3‑D vectors, fingertip positions, and HMD poses. A README.md explains column definitions, units (all in cm), and the half‑scale + rotation preprocessing steps.
