Virtual reality tactile feedback interaction system

Abstract

The invention relates to the virtual reality interaction technology, in particular to a virtual reality tactile feedback interaction system. The virtual reality tactile feedback interaction system comprises a head display module, a storage module, electric stimulus equipment, a time division multiplexing circuit and a flexible electrode array which are sequentially connected. The storage module receives corresponding tactile feedback parameters in virtual scene interaction events, and the corresponding tactile feedback parameters are converted into corresponding electric signals through a driving circuit of the storage module. The electric stimulus equipment controls all electric stimulus channels to output pulse parameters according to the received electric signals, optimal stimulus normal forms felt by all tactile senses are selected through the time division multiplexing circuit, and corresponding pulses are output to the flexible electrode array. The experience effect in a virtualreality scene can be enhanced, meanwhile, the structure and the material of the electrode array are relevantly improved, the modes of electric stimulus are enriched, the accuracy of electric stimulusis improved, and then the immersion of the virtual scene is improved.

Description

technical field [0001] The invention relates to a virtual reality interaction technology, in particular to a virtual reality tactile feedback interaction system based on a flexible electrode array and transcutaneous electrical nerve stimulation. Background technique [0002] With the development of science and technology, virtual reality (Virtual Reality) technology has been widely used, especially in games, film and television, education, teleoperation, medical treatment and other aspects of VR technology has broad prospects. Virtual reality technology is an advanced human-computer interaction technology that effectively simulates human behaviors such as seeing, hearing, and moving in the natural environment. Virtual reality technology constructs a virtual environment through computer graphics, and with the help of corresponding hardware means, such as data gloves, head-mounted displays or stereo glasses, provides sensory stimuli such as sight, hearing, touch, and smell, wh...

Problems solved by technology

[0003] At present, VR devices at home and abroad mainly have the following three deficiencies in the realization of force feedback interaction: First, the interactive feedback technology that integrates vision and hearing has been developed relatively maturely, but in vision, force touch, and even The interactive feedback technology of fusion processing of hearing, hearing and force-tactile senses needs to be improved urgently; then, the form of tactile feedback is mostly realized by means of sensor vibrating the body surface or pressure stimulation, which is not easy to effectively restrain the user during human-computer interaction, It greatly reduces the sense of immersion in the virtual scene; compared with other tactile feedback methods, the electric tactile sense has great advantages. The electric stimulation is simple, lightweight, convenient, high energy conversion efficiency, easy to concentrate and high resolution, so it is extremely Greatly enhances the immersion of the virtual scene; finally, the traditional force feedback interactive device for the whole body or upper body has a large module, inconvenient to wear and high cost, and is not suitable for popularization and application
