Document Type and Number:
WIPO Patent Application WO/2021/159230
Kind Code:
A1
Abstract:
Provided are a brain-computer interface system and method based on sensory transmission. The system comprises: a brain information terminal decoding unit for deciphering neural information, which has been transmitted via sensory organs, of a target object in a non-intrusive manner so as to obtain psychological and physiological data; a psychological emotion modeling unit for recognizing, on the basis of the collected psychological and physiological data, an emotional cognitive state of the target object by utilizing machine learning; and a physical output signal stimulation unit for generating, on the basis of the emotional cognitive state, human-computer interaction information having a sensory stimulation effect so as to prompt the target object to generate an expected emotional cognitive state. The present invention provides a non-invasive brain-computer interface technique for performing decoding and recognition on the basis of a sensory signal flow, such that craniotomy is not needed, there is also no need to be limited by electroencephalogram signals, and the prediction, prevention and intervention of cognitive brain diseases in a timely manner are facilitated.
