摘要:
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 300 generates a stimulation to be applied to users. Biological information acquirers 101a and 101b acquire time-series data of biological information on the users. Parameter extractors 102a and 102b extract a parameter which is changed with a lapse of time by analyzing the time-series data. Thermal sensation estimators 103a and 103b estimate statuses of the users to the stimulation generated by the stimulation generator 300, based on the parameter extracted by the parameter extractors 102a and 102b. A multi-user thermal sensation processor 105 integrates estimation results on the users estimated by the thermal sensation estimators 103a and 103b into a single estimation result. A stimulation controller 104 controls the stimulation generator 300 based on the integrated estimation result.
