Description

technical field

[0001] The invention relates to the technical field of cognitive neuroscience, in particular to a brain-electrically controlled manipulator writing device and a control method. Background technique

[0002] As we all know, for patients with paralysis, amyotrophic lateral sclerosis, stroke, etc., communicating with the external environment has always been a problem. However, with the continuous development of computer technology, clinical rehabilitation technology, psychological technology and sensor technology, brain-computer interface technology is no longer just a fantasy, but a realistic technology.

[0003] Most of the existing brain-computer interface systems for communication use the communication on the computer display screen. Therefore, it cannot meet the actual needs of patients with paralysis, amyotrophic lateral sclerosis, and stroke who want to write actual text. At the same time, most EEG acquisition systems have disadvantages such as bulky and...
