Abstract
A system, medium, and method conducing a user's breathing, in which a sound generated during a user's exhale and/or an ambient temperature change occurring during the exhale is sensed to measure a respiratory waveform of the user. Respiratory information of the user may then be produced from the respiratory waveform, and when the respiratory information of the user is different from normal respiratory information of the user, breathing information according to the normal respiratory information may be provided to the user so the user can use the same to modify their breathing.
