Abstract

The present application relates to the field of industrial virtual reality, and in particular to a virtual reality factory system with force haptics enhancement, which comprises a high-performance computer, a VR headset, a spatial locator, a force feedback controller and a virtual-real interaction unit. The virtual-real interaction unit comprises a VR factory scene, a visual module and a haptic module. Based on spatial positioning, an engineer operates various virtual object models in the VR factory scene through 3D vision provided by the VR headset and haptics provided by the force feedback controller, obtains various force haptics feedback such as friction and gravity, perceives the physical properties of the objects, and performs actions such as touching, moving and grabbing. The present application can provide multi-dimensional perception of "sight, touch and hearing", support immersive operation of the engineer on the VR factory scene, and can be used for future factory applications such as skill training, fault diagnosis and operation in complex and dangerous environments.
