## Abstract

An information processing device includes a controller configured to acquire a detected value of a sensor that detects presence or absence of a person within a predetermined range outside one or more openings that is formed in a wall surface of a first building, each of the one or more openings using light control glass, the wall surface facing outside, and control transmittance of the light control glass based on the detected value of the sensor. A building includes one or more opening that is formed in at least a wall surface that faces outside, the opening using light control glass; a sensor that detects presence or absence of a person within a predetermined range outside the one or more openings; and a control device that controls transmittance of the light control glass based on a detected value of the sensor.

## Claims

### Claim 1

An information processing device comprising a controller configured to:
acquire a detected value of a sensor that detects presence or absence of a person within a predetermined range outside one or more openings that is formed in a wall surface of a first building, each of the one or more openings using light control glass and the wall surface facing outside;
determine whether or not the presence of a person within the predetermined range outside is detected for at least a first opening among the one or more openings based on the detected value of the sensor;
determine whether or not a first condition is satisfied in a case where the presence of a person within the predetermined range outside is detected;
control transmittance of first light control glass used in the first opening such that the first light control glass is placed in a transparent state in a case where the first condition is satisfied; and
control the transmittance of the first light control glass such that the first light control glass is placed in a semi-transparent or opaque state in a case where the first condition is not satisfied; and wherein
the first condition is that outside of the first building is brighter than inside of the first building and
the controller
acquires brightness values detected by light sensors installed inside and outside of the first building and
determines that the outside of the first building is brighter than the inside of the first building in a case where brightness value of the outside of the first building is greater than brightness value of the inside of the first building by a predetermined value or more.

### Claim 2 (depends on 1)

The information processing device according to claim 1, wherein, in a case where presence of a person within the predetermined range outside the first opening is not detected, the controller is configured to control the transmittance of the first light control glass such that the first light control glass becomes transparent.

### Claim 3 (depends on 1)

The information processing device according to claim 1, wherein the first condition is that a person other than a person who is associated with the first building is not detected within the predetermined range outside the first opening.

### Claim 4 (depends on 1)

The information processing device according to claim 1, wherein the first condition is that a curtain that is hung at the first opening is closed.

### Claim 5 (depends on 1)

The information processing device according to claim 1, wherein
each of the one or more openings includes a plurality of sections and includes light control glass in each of the plurality of sections, and
in a case where presence of a person within the predetermined range outside is detected for the first opening, the controller is configured to specify, as the first light control glass, light control glass that is used in a section, among the plurality of sections included in the first opening, that is at a height of an eye level of the person.
