System for estimating thermal comfort

A system comprising:

• a first acquisition unit configured to acquire first biological information of a target, the first acquisition unit including at least one first sensor;
• a second acquisition unit configured to acquire second biological information of the target, the second acquisition unit including at least one second sensor different from the at least one first sensor of the first acquisition unit;
• a first estimation unit configured to estimate a first thermal comfort of the target based on the first biological information;
• a second estimation unit configured to estimate a thermal comfort of the target based on the first biological information and the second biological information;
• and
• a correction unit configured to correct the first thermal comfort, when the second acquisition unit does not acquire the second biological information, using previous thermal comfort of the target estimated by the second estimation unit based on the at least the second biological information previously acquired by the second acquisition unit.

A system comprising:

• a second acquisition unit configured to acquire second biological information of the target, the second acquisition unit including at least one second sensor different from the at least one first sensor of the first acquisition unit;
• a first estimation unit configured to estimate a first thermal comfort of the target based on the first biological information acquired by the first acquisition unit;
• and
• a second estimation unit configured to estimate a second thermal comfort of the target based on the second biological information acquired by the second acquisition unit,
• the first estimation unit being configured to learn a relationship between the first biological information acquired by the first acquisition unit and an estimation result estimated by the second estimation unit to estimate the estimation result estimated by the second estimation unit from the first biological information acquired by the first acquisition unit using a teacher data set that associates the first biological information acquired by the first acquisition unit with the estimation result estimated by the second estimation unit, and
• when the first estimation unit performs estimation, the first thermal comfort based on the first biological information acquired by the first acquisition unit being output.
