Mechanical feedback device and method and virtual reality interaction attachment control method

Abstract

Embodiments of the invention disclose a mechanical feedback device. The device comprises an induction sac and a control unit, wherein the induction sac is used for filling a fluid medium; the induction sac filled with the fluid medium generates tensile force to carry out force feedback after deformation; the control unit is connected with the induction sac through a first conduit; the control unitis used for detecting fluid pressure parameters of the fluid medium in the first conduit and feeding back the fluid pressure parameters to an external controller; and the control units is further used for filling and releasing the induction sab according to a control instruction sent by the external controller. According to the method and device, force feedback is carried out through a manner offilling the fluid medium by using the induction sac, so that the process design is simpler; and the induction sac is a flexible component, so that the third dimension brought to the VR users is stronger.

Description

technical field [0001] The invention relates to the field of virtual display technology, in particular to a mechanical feedback device and method, and a control method for a virtual reality interactive accessory. Background technique [0002] In VR technology, VR devices display virtual scenes for users through head-mounted displays, which can bring users a sense of visual immersion in virtual scenes. However, in VR-based applications, there are still many links that require users to interact with virtual objects in virtual scenes. In order to enhance the realism of users interacting with virtual objects in a virtual reality environment, VR technology also supports some virtual reality Interactive accessories, for example, VR control gloves, leotards that capture movement gestures, etc. [0003] Among these virtual reality interactive accessories, VR control gloves are usually based on mechanical feedback gloves, such as figure 1 As shown, the mechanical feedback mechanism...

Problems solved by technology

[0005] However, the above-mentioned VR control gloves require multiple electric steering gears, and the overall volume of the product is relatively large, and because the mechanical linkage is a hard structure, it is necessary to add more springs and other components to make the user's operation more realistic. cushioning, which makes the process complexity of the existing VR control gloves relatively high
