The present invention includes a memory in which a brain signal-based control program is stored and a processor for executing a program stored in the memory. At this time, the processor determines the intention of a user corresponding to brain signal data based on a brain signal classifier and brain signal data received in real time according to the execution of the program. And the brain signal classifier is a classifier ensemble that includes a plurality of classifiers generated based on the brain signal data previously collected from the user, and determines which one of a plurality of motions is the intention of the user by passing the brain signal data received in real time as an input. Accordingly, the present invention can provide a brain-computer interface device suitable for a device supporting a plurality of commands.
