Electrical stimulator system used for generating artificial tactile sense and artificial-tactile-sense generating method

Abstract

The invention relates to an electrical stimulator system used for generating an artificial tactile sense and an artificial-tactile-sense generating method. The system includes a microcontroller, a constant-current output adjustment circuit, a switching circuit and an electrode plate which are sequentially connected. The microcontroller is connected with the switching circuit, and is also connectedwith a host computer through a communication interface circuit. The method comprises: receiving two-dimensional distribution information of tactile-sense intensity and tactile-sense type informationfrom the host computer by a microcontroller circuit, adjusting current output intensity of the constant-current output adjustment circuit, and realizing different stimulation modes through changing states of all switches in the stimulation signal switching circuit in a time sharing manner according to the tactile-sense type information. The system and the method are based on a high-voltage photoelectric-switch array scheme, realize multi-mode electrical stimulation through changing switch state combination, can generate realistic vibration and compression experience on a skin, and have good position discerning capability.

Description

technical field [0001] The present invention relates to the field of virtual reality. Specifically, it is a tactile virtual reality system and a virtual tactile generation method for helping to enhance the sense of presence. Background technique [0002] Vision, touch, and hearing are the most important sensory components of living things. Although studies have shown that 80% of the information that humans and animals perceive the external world comes from vision, but when it comes to fine and dexterous operations, touch is still the most reliable way of perception. [0003] Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. Immerse yourself in that environment. The current virtual reality technology mainly uses the principle of binocular vision to create a three-dimensional virtual environment through VR glasses, VR helmets, etc., with a surround sound system. ...

AI Technical Summary

Problems solved by technology

This type of method is only suitable for experiments for the study of electrotactile mechanisms, but cannot generate complex tactile patterns on a two-dimensionally distributed plane, so it cannot be applied to generate real-time changing real-time tactile experiences in virtual reality environments.
