To provide an artificial intelligence based method for providing brain information, which makes it possible to collect signals related with the brain of a user in a state of activity so as to determine and feed back a state of the brain.SOLUTION: A method includes: a first step in which a brain signal obtaining unit of a brain signal measuring unit 10 irradiates a user's brain with a near-infrared ray and detects light transmitted through the cerebral cortex; a second step in which a brain signal processing unit of the brain signal measuring unit determines a level of oxygenation of hemoglobin in the cerebral blood flow on the basis of the detected light; a third step in which a brain signal analyzing unit extracts activated at least one brain activation area from a plurality of areas of the brain on the basis of the determined level of oxygenation of hemoglobin; and a fourth step in which a diagnosing unit 50 determines a state of the brain on the basis of the at least one brain activation area extracted successively for a predetermined period of time; where a signal collecting operation of the brain signal obtaining unit in the step 1 is performed in a state where the user is moving.SELECTED DRAWING: Figure 1
