System, medium, and method to conduce a user's breathing

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.

What is claimed is: 
     
         1 . A method of conducing a user's breathing, the method comprising:
 detecting a user's breathing;   generating a current respiratory information of the user based on the user's breathing, with the current respiratory information including a current respiratory cycle and/or current respiratory rate of the user; and   comparing the current respiratory information with predefined respiratory information of the user, and displaying and/or representing the predefined respiratory information to the user through a display and/or an audio output if the current respiratory information and the predefined respiratory information are different,   wherein, when the current respiratory information and the predefined respiratory information are different, the generating of the current respiratory information continues while the predefined respiratory information is displayed and/or represented to the user through the display and/or audio output, and   wherein the comparing of the current respiratory information further comprises providing visual and/or audio feedback to the user to indicate a progression of the user's breathing in matching the predefined respiratory information.   
     
     
         2 . The method of  claim 1 , further comprising maintaining the predefined respiratory information in a memory, the predefined respiratory information being a normal respiratory cycle and/or normal respiratory rate of the user, with the normal respiratory cycle and/or normal respiratory rate representing a breathing state of the user that does not indicate stress. 
     
     
         3 . The method of  claim 2 , wherein the normal respiratory cycle and normal respiratory rate are previously generated by the generating of the current respiratory information when the user's breathing was the breathing state of the user that does not indicate stress. 
     
     
         4 . The method of  claim 1 , wherein the detecting of the user's breathing is performed by detecting an audible aspect of the user's breathing and/or by detecting an ambient temperature change during an exhale. 
     
     
         5 . The method of  claim 4 , wherein the comparing of the current respiratory information, the displaying and/or representing of the predefined respiratory information to the user, and providing of visual and/or audio feedback to the user are performed by a portable device includes at least one of a mobile communication terminal, a personal digital assistant (PDA), a handheld gaming device, an MP 3  player, a PMP (Portable Multimedia Player), a digital multimedia broadcasting (DMB) terminal, and a notebook computer. 
     
     
         6 . The method of  claim 1 , wherein a period of the user's breathing is determined to be an exhale period based on a magnitude of the user's breathing being greater than a predetermined threshold value, wherein a period of the user's breathing during which the magnitude of the user's breathing is not greater than the predetermined threshold value is determined to be an inhale period of the user's breathing, and wherein the comparison of the current respiratory information with the predefined respiratory information is based on the exhale period and the inhale period. 
     
     
         7 . The method of  claim 6 , wherein the predetermined threshold represents a change in a detected ambient temperature and/or a detected sound level. 
     
     
         8 . The method of  claim 6 , further comprising adding the exhale period and the inhaled period to calculate the current respiratory cycle, dividing the exhale period by the inhale period to calculate the current respiratory rate, and using the current respiratory cycle and/or the current respiratory rate in the comparison of the current respiratory information with the predefined respiratory information. 
     
     
         9 . The method of  claim 6 , further comprising displaying and/or representing detected exhale information and/or detected inhale information of the detected user's breathing in the providing of the visual and/or audio feedback to the user through the display and/or the audio output together with predefined exhale information and/or predefined inhale information of the predefined respiratory information.
