According to an embodiment of the present invention, provided is an apparatus for generating a spatial-frequency feature map which includes a memory in which a program for generating a spatial-frequency feature map is stored, and a processor for running the program stored in the memory. The processor receives a user′s motion imaginary brain signal measured by a brain signal measuring unit according to the execution of the program, sets a frequency band optimized for each user from the received brain signal, filters the brain signal through the optimal frequency band set, extracts a 2D feature map from the filtered brain signal, and generates an input map by voxeling the extracted 2D feature map into 3D.
