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.

Claims

1. An eyewear comprising:

a frame;

a first electrode positioned to abut 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, wherein

the electrode holding unit has;

a first member placed in the frame; and

a second member that is electrically connected with the first member, and moves relative to the first member, and

the first electrode is provided on a front surface of the second member and

wherein

the first member holds the second member such that if a certain degree of force is applied thereto, the distance between the frame and the first electrode changes stepwise; and

the distance between the frame and the first electrode is defined as a total length of a length between an end portion of the second member opposite to the front surface and the frame and a thickness of the second member.

2. The eyewear according to claim 1, wherein the first member includes a plurality of steps for locking the second member and a structure in which the lock is unlocked if a certain degree of force is applied.

3. The eyewear according to claim 1, further comprising:

a pair of nose pads connected to the frame; and

a pair of second electrodes placed on front surfaces of the pair of nose pads.

4. The eyewear according to claim 3, further comprising an eye potential detecting unit that is electrically connected to the first electrode and the pair of second electrodes, and detects an eye potential of the wearer.

5. An eyewear comprising:

a frame;

a first electrode positioned to abut 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, wherein

the electrode holding unit has;

a first member placed in the frame; and

a second member that is electrically connected with the first member, and moves relative to the first member, and

the first electrode is provided on a front surface of the second member and

wherein

the first member includes a screw structure and holds the second member by the screw structure, and

the distance between the frame and the first electrode is defined as a total length of a length between an end portion of the second member opposite to the front surface and the frame and a thickness of the second member.

6. The eyewear according to claim 5, further comprising:

a pair of nose pads connected to the frame; and

a pair of second electrodes placed on front surfaces of the pair of nose pads.

7. The eyewear according to claim 6, further comprising an eye potential detecting unit that is electrically connected to the first electrode and the pair of second electrodes, and detects an eye potential of the wearer.
