Abstract

Eyewear having: an optical module; an input unit; a sensing unit; a storage unit that stores at least conditions that change optical properties of the optical module; and a control unit that performs electric control of the optical module, in accordance with a set mode, by using electric control. The set modes include: a first mode in which the control unit electrically controls the optical module on the basis of a condition stored in the storage unit and a detection value for the sensing unit; and a second mode in which the control unit electrically controls the optical module on the basis of instructions received by the input unit. The conditions stored in the storage unit are updated on the basis of the detection value for the sensing unit when the input unit has received an instruction in the second mode.

First claim

What is claimed is:

1. An eyewear comprising:
an electric control lens whose optical characteristics change;
an input receiver configured to receive an instruction from a user;
a sensor configured to detect a use condition of the electric control lens;
a storage configured to store at least a condition of changing the optical characteristics of the electric control lens; and
a controller configured to change the optical characteristics of the electric control lens by an electric control in accordance with a setting mode,
wherein the setting mode includes at least:
a first mode in which the controller performs the electric control on the electric control lens on a basis of the condition stored in the storage and a detection value of the sensor, and
a second mode in which the controller performs the electric control on the electric control lens on a basis of the instruction received by the input receiver,
wherein the condition stored in the storage is updated on a basis of the detection value when the detection value of the sensor section that is obtained at the time when the input receiver receives the instruction in the second mode is shifted from the condition stored in the storage by a prescribed value or more.

2. The eyewear according to claim 1 , wherein in the first mode, the controller performs the electric control on the electric control lens on a basis of the condition updated on the basis of the detection value of the sensor section that is obtained at the time when the touch sensor receives the instruction in the second mode.

3. The eyewear according to claim 1 , wherein the sensor includes at least one of an inclination sensor and an illuminance sensor.

4. The eyewear according to claim 3 , wherein the sensor further includes a mechanical switch, a position detection sensor, an acceleration sensor, an angular velocity sensor, a gyro sensor, a proximity sensor, a contact sensor, a communication device, an imaging device, or a combination thereof.

5. The eyewear according to claim 1 , wherein the controller changes a refractive index of the electric control lens, and/or a transmittance of the electric control lens with respect to visible light.

6. The eyewear according to claim 1 , wherein the condition stored in the storage is updated on the basis of the detection value of the sensor that is obtained at the time when the touch sensor receives the instruction in the second mode.

7. The eyewear according to claim 1 , wherein the condition stored in the storage is updated on a basis of the detection value in accordance with a number of times of acquisition of the detection value of the sensor at the time when the input receiver receives the instruction in the second mode.

8. The eyewear according to claim 7 , wherein the condition stored in the storage is updated on a basis of the detection value when the detection value of the sensor that is obtained at the time when the input receiver receives the instruction in the second mode falls within a same range by a prescribed number of times.
