Blooming: A Handheld Device Using Flywheel to Simulates Various Multi-Force Feedback

Enhancing the immersive experience in virtual reality (VR) through external force has always been a hot topic. The development and research of external devices have been published from time to time. Various interactive devices could increase the sensory experience at the tactile aspect in addition to sight and hearing. This research has proposed a device for VR, which could adjust its rotational speed through the individual flywheels on six axes of tilt to generate changes in inertia moment to create force feedback. The device mainly acts on the user's hand to simulate the feedback felt by the hand in the VR world: 1) the reaction force and friction of the handheld weapon hitting the object, 2) the fictitious magic effect, 3) simulating different environments to feel the force feedback brought by gravity and resistance to the hand, to achieve a more substantial experience immersion.
