Abstract
The invention discloses a sleep quality monitoring method based on a smartphone and belongs to the technical field of mobile sensing of smart phones. Firstly, a sensor of the phone is utilized to acquire sleep-related physiological characteristic signals in the sleeping process, then characteristic extraction is conducted on the physiological characteristic signals, then a fuzzy logic theoreticalmethod is utilized to map corresponding characteristics into corresponding sleep states, and finally sleep quality score is given according to age and environment lighting information of sleepers. Bycomparing 20 groups of sleep data, the judgement accuracy of rapid-eye-movement sleep (REM) can be up to 75.3%, the judgement accuracy of a light sleep stage is up to 81.2%, and the judgement accuracyof a deep sleep state is up to 78.8%. It can be found that the judgement accuracy of light sleep is the highest and the judgement accuracy of REM is the lowest because that brain neuron activities atthe REM stage and a sober stage are similar, the two stages cannot be effectively distinguished according to limb movements and breathing frequency and accordingly erroneous judgement is likely caused.
