Hand motion sensing device for virtual reality and glove assembly thereof capable of enhancing the real interactive behaviors such as touch, swing, and instant feedback in the virtual reality interactive experience to achieve the authenticity of real hands blended into the space

This invention discloses a hand motion sensing device for virtual reality, comprising a glove assembly and a motion response module. The glove assembly is a multilayer kit that can be assembled and disassembled and comprises a non-slip covering member, a sleeving member, and a protective member. The sleeving member and the protective member comprise a hand back part and five half-finger sleeve parts extended outward from the hand back part to form a five-claw finger sleeve structure. The action response module comprises a finger sensing unit, a control unit, a wireless transceiving unit, and a power supply unit disposed between layers of the multilayer kit for tracking the hand movements of a user in a virtual reality environment. The finger sensing unit comprises a plurality of inertial sensors, which are configured according to the hand back, the connection position from the hand back to each finger, and the position of each finger joint of the user, and generate a motion message according to the hand movem
