## Abstract

A first determination unit determines whether a movement of an eyelid or an eyebrow of a wearer has occurred, based on an electric signal measured by a measurement electrode with a common electrode as a ground potential. A second determination unit determines that a movement of a face of the wearer has occurred when a distortion detection unit detects distortion of the spectacle frame. An output unit outputs a command due to operation of the spectacle frame by the wearer when the first determination unit determines that the movement of the eyelid or the eyebrow of the wearer has occurred and at the same time the second determination unit determines that the movement of the face of the wearer has occurred.

## Claims

### Claim at position 1

1-4. (canceled)

### Claim 5

An information input device comprising:
a spectacle frame;
a measurement electrode provided in the spectacle frame and configured to measure an electric signal caused by a movement of an eyelid or an eyebrow of a wearer of the spectacle frame;
a distortion detection circuit in the spectacle frame and configured to detect distortion of the spectacle frame;
a first determination circuit configured to determine whether the movement of the eyelid or the eyebrow of the wearer has occurred, based on the electric signal measured by the measurement electrode;
a second determination circuit configured to determine that a movement of a face of the wearer has occurred when the distortion detection circuit detects the distortion of the spectacle frame; and
an output circuit configured to output a command due to operation of the spectacle frame by the wearer when the first determination circuit determines that the movement of the eyelid or the eyebrow of the wearer has occurred concurrently with the second determination circuit determining that the movement of the face of the wearer has occurred.

### Claim 6 (depends on 5)
