Abstract
Disclosed is an apparatus for memory enhancement based on electroencephalogram according to one embodiment of the present invention. According to the present invention, it is possible to identify forgotten items during retrieval in a re-learning process based on a user's brain signals measured in an initial learning process by means of a brain signal measurement unit capable of measuring brain signals, and provide the user with repetitive learning depending on the user's electrophysiological characteristics, resulting in a more effective enhancement of memory.
Claims9
An apparatus for memory enhancement based on electroencephalogram, the apparatus comprising:
- a brain signal measurement unit that measures a user's brain signal;
- a preprocessing unit that extracts theta waves from the brain signal through power spectrum analysis;
- a memory ability determination unit that determines a user's memory ability based on the theta waves extracted by the preprocessing unit;
- a communication unit that transmits first encoding information to a user terminal and receives first retrieval information corresponding to the first encoding information from the user terminal;
- and
- a learning method providing unit that provides a learning method tailored to the user's memory ability based on a determination result by the memory ability determination units,
- wherein the brain signal measurement unit measures a first brain signal if the communication unit receives the first retrieval information corresponding to the first encoding information from the user terminal,
- wherein the memory ability determination unit determines a memory ability based on a first theta waves extraction result extracted by the preprocessing unit from a measurement result of the first brain signal,
- wherein the communication unit receives third retrieval information corresponding to the first encoding information from the user terminal within a predetermined reference time if a memory ability determined by the memory ability determination unit is a short-term memory ability,
- wherein the brain signal measurement unit measures a fourth brain signal if the communication unit receives the third retrieval information corresponding to the first encoding information from the user terminal within the predetermined reference time,
- wherein the memory ability determination unit determines a memory ability as a long-term memory ability based on a fourth theta wave extraction result extracted by the preprocessing unit from a measurement result of the fourth brain signal,
- wherein the learning method providing unit provides a learning method tailored to the long-term memory ability, and
- wherein encoding information includes information for memorization, and retrieval information includes an answer to the information for memorization.
