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.

Abstract: An information processing device that is able to communicate with a vehicle includes: a control unit; and a communication unit. The control unit acquires driving information of another vehicle traveling around the vehicle via the communication unit, and transmits at least part of the driving information to the vehicle via the communication unit when the driving information indicates content of driving that reduces wear and tear of a component of the other vehicle.

Abstract: A more appropriate proposal is made far an action to be performed by a user in a free time of his or her schedule. A controller is provided which performs: obtaining schedules of a user; and transmitting to a terminal of the user, based on a content of a first schedule among the schedules of the user, a proposal for an action of the user to change his or her mood in a first free time in which the user has no schedule immediately before the first schedule.

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.

Abstract: An information processing apparatus includes a controller configured to monitor movement of at least one object that is owned by a first user, based on information detected by a sensor, and create a list of lendable objects from the at least one object, based on the movement of the at least one object. The controller adds an object a frequency of use of which is smaller than a first value, among the at least one object, to the list as the lendable object.

Abstract: A controller is provided that is configured to perform: specifying a first user who is a user before boarding a moving vehicle; specifying a second user who is a user sitting on a seat in the moving vehicle; transmitting an inquiry to a terminal of the second user about whether or not to offer his or her seat; and notifying a terminal of the first user that the first user can take a seat in the moving vehicle, when a response to the effect that a seat is offered is received from the terminal of the second user.

Abstract: An information processing device includes a controller. The controller is configured to detect an obstruction present on a road, is configured to detect a user present within a predetermined distance from the obstruction that is detected, and is configured to transmit, to a terminal of the user that is detected, a request to relocate the obstruction.
