A human fatigue assessment device capable of performing highly accurate fatigue assessment is provided. The human fatigue assessment device includes: a physiological signal measuring unit which measures a pulse wave signal of a user; a feature value extracting unit which extracts first feature values each of which is obtained from a systolic posterior component of the pulse wave signal measured by the physiological signal measuring unit; a storage unit in which the first feature values extracted by the feature value extracting unit are stored; and a fatigue determining unit which determines whether or not the user is fatigued, using the first feature values extracted by the feature value extracting unit, in which the fatigue determining unit compares a first feature value among the first feature values extracted by the feature value extracting unit and at least one of the first feature values stored in the storage unit, to determine whether or not the user is fatigued.

Comfortable sensation of living bodies is estimated, considering individual differences in biological information on the living bodies staying or residing in a common space, and stimulation contents is properly controlled. A stimulation generator generates a stimulation to be applied to users. Biological information acquirers and acquire time-series data of biological information on the users. Parameter extractors and extract a parameter which is changed with a lapse of time by analyzing the time-series data. Thermal sensation estimators and estimate statuses of the users to the stimulation generated by the stimulation generator, based on the parameter extracted by the parameter extractors and. A multi-user thermal sensation processor integrates estimation results on the users estimated by the thermal sensation estimators and into a single estimation result. A stimulation controller controls the stimulation generator based on the integrated estimation result.

Environment control device, environment control method, environment control program, and environment control system

An environment control device, an environment control method, an environment control program, and a computer-readable recording medium containing the environment control program for enabling the user to actually have a comfortable feeling in a reliable manner and further to maintain such a comfortable state, are provided. A biological information measuring portion acquires time-series data of the biological information of the user. A chaos analysis portion calculates a parameter about the biological information through chaos analysis of the time-series data acquired by the biological information measuring portion. A state inferring portion infers a comfortable feeling of the user on the basis of the parameter calculated by the chaos analysis portion. A device control portion controls generation of a stimulus to be given to the user on the basis of the result of inference made by the state inferring portion.

A control unit is provided which is capable of estimating a user's environment based on time and temperature before entering an air-conditioned room, and reflecting a result obtained from the estimation in the control of air-conditioning equipment. An interface sectionreceives user information indicating the state of a user in a first area and temperature data in the first area; a temperature-data recording sectionrecords a period of time when the user has stayed in the first area, and by relating the temperature data to the period of time clocked by a timer section, records this temperature data as a temporal change in the temperature of the first area; a special-mode reference sectionstores control information for changing the contents of a setting in air-conditioning equipmentprovided in a second area; a special-mode time calculation sectioncalculates an execution time to execute a control operation of the air-conditioning equipmentbased on the control information, using the period of time when the user has stayed in the first area, the temporal change in the temperature and a reference temperature which is a predetermined temperature; and an operation-data generation sectiongenerates operation data for operating the air-conditioning equipmentduring the execution time based on the control information.

An operating condition determiner compares an operation starting time (t) of network-connected first consuming apparatuses received by a schedule information receiver and a consumption starting time (t) predicted by a predicting system based on a total consumption amount of the first consuming apparatuses and a second consuming apparatus, which is not network-connected, and determines the operation starting time (t) as an operation starting time of a fuel cell if the operation starting time (t) is earlier than the consumption starting time (t) while determining the consumption starting time (t) as such if the operation starting time (t) is later than the consumption starting time (t), so that the fuel cell can stably generate power. The fuel cell can stably supply power at a time when the consuming apparatuses start consuming power. The merit of introducing a cogeneration facility can be sufficiently exhibited even if both consuming apparatuses provided with a network connecting function and those provided with no such function exist.
