In this paper, a novel method combining MYO Armband and Leap Motion is proposed to apply in Virtual Reality display tasks. With the proposed method, we address the Leap Motion's problem of lost detection and improve the Leap Motion's robustness. By integrating MYO and Leap Motion, we can obtain the user's palm's position with MYO, while Leap Motion fails to detect the user's hands. A rigorous analysis is also given in this paper. The validity of the proposed method is verified by simulations with OpenSim.
