Differences in perceptions between virtual reality (VR) and reality prevent immersion in VR. To improve immersion in VR, many methods have adopted haptic feedback in VR using pseudo-haptics. However, these methods have little evaluated the effect of force feedback on pseudo-haptics that reflect the user’s state. This paper proposes and evaluates the pseudo-haptics system that manipulates the control/display (C/D) ratio between reality and VR using muscle activity measured. We conducted a user study under three conditions: the C/D ratio is constant, large, or small, depending on the muscle activity. Our results indicated that pseudo-haptics were effective for small C/D ratio settings during low myoelectric intensity.
