Abstract
A device disclosure includes a unit that measures an eye potential; and a unit that sets a threshold coefficient based on a frequency characteristic value of eye potential differential values and sets an upper threshold and a lower threshold based on a number obtained by multiplying a standard deviation of the eye potential differential values by the threshold coefficient, and detects a change in the eye potential differential values as the eyeblink waveform wherein the change occurs in the time-series data on the eye potential differential values either when the eye potential differential value becomes larger than the upper threshold and, after that, changes from the upper threshold to the lower threshold within a predetermined time or when the eye potential differential value becomes smaller than the lower threshold and, after that, changes from the lower threshold to the upper threshold within the predetermined time.
