Abstract: An information processing method is executed by a computer having a control unit, wherein the control unit executes: acquiring a plurality of biological signals; detecting for each predetermined time unit a peak part of the respective biological signals; attaching identical identification information to one or a plurality of peak parts forming an identical peak when attaching peak identification information to each of the biological signals; and extracting a combination of corresponding peaks from at least two biological signals on the basis of the identification information of each time unit of the at least two biological signals.

Abstract: An optical element has a transmission spectrum characterized in that a local maximum falls within a wavelength region longer than 315 nm but shorter than or equal to 400 nm, a local minimum falls within a wavelength region longer than or equal to 380 nm but shorter than or equal to 500 nm, and the wavelength at the local maximum is shorter than the wavelength at the local minimum.

Abstract: A technique to detect an eye potential of a wearer of an eyewear by using an electrode abutting on the glabella of the wearer has been known, but it is desirable to surely cause the electrode to abut on the glabella so as to prevent deterioration in the detection accuracy of detecting a biosignal indicating an eye potential, myogenic potential, brain wave or the like. In view of this, an eyewear including: a frame; a first electrode that abuts on a glabella of a wearer of the eyewear; and an electrode holding unit that holds the first electrode such that a distance between the frame and the first electrode is changeable is included.
