Method and device for determining sleeping pattern, and computer readable storage medium recording the method

A device for determining a sleeping pattern, the device comprising:

• a signal measuring sensor configured to measure a first bio-signal from a user in an unrestrictive manner;
• a bio-signal extractor configured to extract a second bio-signal including a motion signal and a respiration signal, based on the first bio-signal;
• a reference signal determiner configured to determine an apnea measurement reference signal including a respiration measurement signal and a motion measurement signal, based on the second bio-signal;
• an evaluation signal generator configured to generate a first evaluation signal based on the apnea measurement reference and a first time interval, and generate a plurality of second evaluation signals by dividing the first evaluation signal by a second time interval, that is smaller than the first time interval;
• a standard deviation information calculator configured to calculate standard deviation information based on the second evaluation signals;
• and
• a sleeping pattern determiner configured to determine a sleeping pattern for the second time interval corresponding to the second evaluation signals, based on the standard deviation information, the sleeping pattern comprising at least one of a motion estimation section, an apnea estimation section, and a normal respiration estimation section.
