A computing device based on a brain computer interface (BCI) for providing a common pattern of brain signals includes a memory storing a program to provide the common pattern and a processor to execute the program stored in the memory. The processor preprocesses brain signals of users, extracts features of the preprocessed brain signals to store the features in a database, generates a plurality of brain wave feature patterns defined by the features of the brain signals and classifier parameters for classifying motion imaginations based on the features, and extracts a brain wave common pattern existing in common for each motion imagination for the entire users from the brain wave feature patterns by executing the program.
