Description

technical field [0001] The present invention relates to the field of application research of brain-computer interface, in particular, to a device and method based on brain-computer interface technology. Background technique [0002] Brain-Computer Interface (BCI) is to establish a direct information exchange and control channel between the human brain and computers or other electronic devices that does not depend on conventional brain output channels (peripheral nerves and muscle tissue). A new human-computer interaction system. As a new information exchange technology, brain-computer interface can provide people with a new way to communicate with the outside world. [0003] For patients with language barriers, especially those with severe paralysis, it is difficult to express their emotions to the outside world through language or body language. In China, speech disabilities rank first among the five major disabilities including visual disabilities, physical disabilities,...
