Pure idea nerve muscle electrical stimulation control and nerve function evaluation system

Abstract

The invention discloses a pure idea nerve muscle electrical stimulation control and nerve function evaluation system which comprises a signal collecting module, a signal processing module and an instruction control module. The signal collecting module is used for collecting input electroencephalogram signals and other physiological signals in real time; the signal processing module is used for reading the electroencephalogram signals, carrying out feature extracting through a cospace model algorithm, and carrying out mode recognition on feature data through a support vector machine to obtain a decision value; according to the decision value and the decision value threshold vale range, an idea imagination mode is judged and transmitted to the instruction control module; the instruction control module is used for converting the idea imagination mode into a trigger nerve muscle electrical stimulator switch so that nerve muscle electrical stimulation can be carried out on the limb part of a user. The system has the advantages of high stability and adaptation, and lays the foundation for the large-scale application stage of an idea control system, and it is hopeful to obtain considerable social benefits and economic benefits.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a purely mental neuromuscular electrical stimulation control and nerve function evaluation system. Background technique [0002] Brain-computer interface (BCI) is a communication control system that does not depend on the normal output channels of peripheral nerves and muscles in the brain. In the current research results, it mainly collects and analyzes human EEG signals in different states, and then uses certain engineering techniques to establish a direct communication and control channel between the human brain and computers or other electronic devices, thereby To realize a brand-new information exchange and control technology can directly express wishes or manipulate external devices by controlling brain electricity without language or body movements. Among the existing brain-computer interfaces, motor imagery is a paradigm based on pure ideas. [0003] When not d...

Problems solved by technology

[0007] Some operations and activities in real life are complex, and completing a specific action task requires more steps and different operating procedures

For example, assisting in grasping a water cup to drink water requires the two basic functions of moving and grasping without considering the speed of movement and grasping degree. Therefore, the imagination of simple body movements is not enough to match the user to complete a specific task in daily life. action in task
