Virtual Muscle Force: Communicating Kinesthetic Forces Through Pseudo-Haptic Feedback and Muscle ...
summary
System maps EMG from a MYO armband on biceps/triceps and scales it (calibrated 0–1 × ~110 N) to add a muscle-generated force to a pseudo‑haptic offset while running on an Oculus Rift. A user study with 21 participants (within‑subjects: no haptics, pseudo‑haptics, pseudo‑haptics+muscle) uses tasks like cranking a wheel and lifting a chest; muscle input increases perceived resistance, realism, enjoyment and control but adds effort, requires per‑user calibration, and can fatigue users over time.
