AI Technical Summary

Technical Problem

Existing EEG-responsive training systems for dogs or small animals generally suffer from insufficient spatiotemporal alignment accuracy in practical applications, leading to electrode position drift, changes in contact impedance, and asynchronous subsystem clocks. This results in inconsistencies in the spatial coordinates or timestamps of the sampled data, which in turn causes errors in feature extraction and trigger determination based on this data, reducing training effectiveness and increasing unnecessary stimulation burden.

Method used

High-precision EEG data acquisition is achieved using a flexible dry electrode array and a low-power wireless transmission module. Electrode position correction and global time synchronization are performed using a time-space alignment module. The characteristics of theta wave power spectral density, α-θ ratio, instantaneous phase synchronization, and attention index are calculated using a feature extraction and recognition module. Stimulus parameters are set using a judgment and parameter adaptation module. Behavioral reinforcement based on the principle of operant conditioning is achieved through a human-computer interaction module, supporting manual intervention and multimodal reinforcement.

Benefits of technology

It improves the spatiotemporal alignment accuracy of the training system, reduces false triggers, ensures that stimuli are accurately delivered when the dog experiences the desired physiological event, enhances the consistency and reliability of the "stimulus-dog response" sequence during training, and improves training effectiveness and safety.

Abstract

The invention discloses an electroencephalogram response type nerve stimulation training system for dogs and a control method, and relates to the technical field of brain-computer interface application. A time-space alignment module; a feature extraction and identification module; a judgment and parameter self-adaption module; a nerve stimulation module; and a man-machine interaction module. Repeatable and low-time-delay alignment potential data are generated through real-time tracking and global clock alignment of the position of the dog head electrode in combination with high-quality electroencephalogram collection and pane-level feature extraction. Based on the judgment of the data, the real neural activity of the dog can be accurately corresponding in time and space, it is guaranteed that when the expected physiological event of the dog occurs, the award stimulation generated by the nerve stimulation module is accurate and in place, and the consistency and reliability of the stimulation-dog reaction time sequence in training are improved. The operating conditioned reflex principle is applied, and stimulation of the nerve stimulation module can be triggered by the remote controller when the dog has expected behaviors.
