PROBLEM TO BE SOLVED: To provide a brain-wave frequency detection device capable of highly accurately acquiring an output of BCI (Brain Computer Interface) using SSVEP (Steady-State Visual Evoked Potential) without any need of learning.SOLUTION: The brain-wave frequency detection device includes: a brain wave measurement part that measures a brain wave emitted from a primary visual cortex; a cycle data segmentation part that segments, for each of a plurality of prescribed cycles, cycle data from the brain wave, with each time of the prescribed cycle defined as a start time; an arithmetic average calculation part that adds the cycle data for each prescribed cycle; and an additive-method frequency detection part that detects, in the prescribed cycle, a frequency corresponding to a cycle where a difference between positive/negative peak intensities of data obtained by adding the cycle data for each prescribed cycle is maximized. |
