DEVICE AND METHOD FOR PROVIDING COMMON PATTERN OF PLURALITY OF BRAIN SIGNAL

摘要

A brain computer interface (BCI) -based computing device that provides a common pattern of brain signals includes a memory in which the common pattern providing program is stored, and a processor executing a program stored in the memory. At this time, according to the execution of the program, the processor performs preprocessing on the brain signals of each user, extracts the characteristics of the preprocessed brain signals, stores them in a database, A plurality of brain signal feature patterns defined by a classifier parameter for classifying each operation imagemay be generated and a common brain signal common pattern that is common to each operation imagination for all users is extracted from the brain signal feature patterns do..
