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.

Claims

1. An eyewear comprising:

an optical module whose optical characteristics change;

an input section configured to receive an instruction from a user;

a sensor section configured to detect a use condition of the optical module;

a storage section configured to store at least a condition of changing the optical characteristics of the optical module; and

a control section configured to change the optical characteristics of the optical module by an electric control in accordance with a setting mode,

wherein the setting mode includes at least

a first mode in which the control section performs the electric control on the optical module on a basis of the condition stored in the storage section and a detection value of the sensor section, and

a second mode in which the control section performs the electric control on the optical module on a basis of the instruction received by the input section, and

wherein the condition stored in the storage section is updated on a basis of a detection value of the sensor section that is obtained at a time when the input section receives an instruction in the second mode.

2. The eyewear according to claim 1, wherein in the first mode, the control section performs the electric control on the optical module 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 input section receives the instruction in the second mode.

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

4. The eyewear according to claim 3, wherein the sensor section 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 control section changes a refractive index of the optical module, and/or a transmittance of the optical module with respect to visible light.

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

7. The eyewear according to claim 1, wherein the condition stored in the storage section is updated on a basis of the detection value in accordance with a result of comparison between the detection value of the sensor section that is obtained at the time when the input section receives the instruction in the second mode and the condition stored in the storage section.

8. The eyewear according to claim 7, wherein the condition stored in the storage section 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 section receives the instruction in the second mode is shifted from the condition stored in the storage section by a prescribed value or more.

9. The eyewear according to claim 1, wherein the condition stored in the storage section 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 section at the time when the input section receives the instruction in the second mode.

10. The eyewear according to claim 9, wherein the condition stored in the storage section 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 section receives the instruction in the second mode falls within a same range by a prescribed number of times.
