Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0028] On this basis, the present invention also proposes a pure idea control system based on compound limb imagination movements and continuous movement sequence imagination. Coordinated movement imagination involving two or more limb parts in the motor area of ​​the cerebral cortex is defined as compound limb imagination movement, while sequential imagination of multiple simple or complex limb movements is called continuous movement sequence imagination movement. From the development in recent years, it can be seen that the brain-computer interface based on imaginative actions has gradually developed towards the more complex collaborative movement imagination of various limb parts. Compared with simple imaginary movements of limbs, imaginative movements of complex limbs and co...

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...
