Abstract

A virtual reality haptic feedback interaction system, comprising a head display module, a storage module, an electrical stimulation device, a time-division multiplexing circuit, and a flexible electrode array connected in sequence. The storage module receives haptic feedback parameters corresponding to virtual scene interaction events, and converts the corresponding haptic feedback parameters into corresponding electrical signals through its drive circuit; the electrical stimulation device controls the output pulse parameters of each electrical stimulation channel according to the received electrical signals. The time-division multiplexing circuit selects the optimal stimulation paradigm for each haptic experience, and outputs the corresponding pulse to the flexible electrode array.
