Abstract: An intellectual productivity evaluation device includes: an obtainment unit configured to obtain a set of answer times required by a subject to accomplish a task of answering a plurality of questions, the task being imposed on the subject as intellectual work; an evaluation unit configured to calculate an evaluation value related to a depth of concentration of the subject in a concentrated state using the set of answer times obtained by the obtainment unit based on a model in which the subject is in the concentrated state or an unconcentrated state during the intellectual work; and an output unit configured to output evaluation value information indicating the evaluation value calculated by the evaluation unit.

Abstract: An information providing method includes: generating first information indicating that a user who is interested in first content is relaxing, when (i) a current behavior of the user includes a predefined behavior and (ii) the first content included in information on communication content and second content included in information indicating a shopping history are the same content; obtaining, from a second information processing apparatus connected to a first information processing apparatus, information indicating first request content over a network; and when content of the first information is included in the first request content, outputting, to the second information processing apparatus, second information including information for identifying the user or a space, using the generated first information.

Abstract: An information providing method includes: when door information indicating whether a door of the refrigerator is open or closed and information indicating a change in the amount of an item in the refrigerator indicate that there is no change in the amount of the item between the door of the refrigerator being opened and closed, generating first information indicating that a user opened the door of the refrigerator but an item the user wanted was not in the refrigerator; obtaining, from a second information processing apparatus connected to a first information processing apparatus, information indicating first request content over a network; and when content of the first information is included in the first request content, outputting, to the second information processing apparatus, second information including information for identifying the user or the home, using the first information generated.

Abstract: An information providing method includes: generating first information indicating there is an item that has been stored in a storage for a long time when (i) a length of a stored period of the item is a first threshold amount of time or longer and (ii) an amount of time from the current time to a statistical time is a second threshold amount of time or less; obtaining, from a second information processing apparatus connected to a first information processing apparatus, information indicating first request content over a network; and when content of the first information is included in the first request content, outputting, to the second information processing apparatus, second information including information for identifying a user or a space, using the first information generated.

Abstract: An air environment control system includes one or more adjustment devices that adjust an air environment in a space; and a control device that controls the one or more adjustment devices. The air environment control device includes an air environment control unit that controls (i) at least one of the one or more adjustment devices to create a cooler environment in the space, when a person does intellectual work in the space; and (ii) at least one of the one or more adjustment devices to create a warmer environment warmer than the cooler environment in the space, when the person has a break in the space. The control unit further controls at least one of the one or more adjustment devices to apply cool stimulation to the person, when the person starts the intellectual work in the space.

Abstract: Provided is an environment control system that controls an environment of a space in which a user performs an intellectual task. The environment control system includes: a controller which performs scene control for reproducing one or more predetermined scenes in the space by controlling one or more luminaires that emit illumination light that illuminates a predetermined area in the space and one or more air conditioning devices that air-condition the space. The one or more predetermined scenes include: a concentration scene that causes the user to concentrate on the intellectual task; and a rest scene that eases the concentration of the user. The controller switches between concentration scene control for reproducing the concentration scene and rest scene control for reproducing the rest scene when a predetermined condition is satisfied.

Abstract: Provided is an environment control system that controls an environment of a space. The environment control system includes: a controller that performs scene control for reproducing one or more predetermined scenes in the space. The controller includes: a lighting controller that adjusts an illuminance or a color temperature of illumination light that is emitted by one or more luminaires and illuminates a predetermined area in the space, by controlling the one or more luminaires; and an air conditioning controller that adjusts a temperature, a humidity, and an airflow in the space by controlling one or more air conditioning devices that air-condition the space. The controller performs the scene control by adjusting the illuminance or the temperature of the illumination light, and the temperature, the humidity, and the airflow in the space.
