Research on sleeping posture recognition method based on pressure sensor

Abstract

Using the structure of the butterfly pillow is the most simplest identification method, combined with the pressure sensor. The resistance value of the pressure sensor is obtained by analog-to-digital converter (A/D). The change of resistance of pressure sensors under different sleeping postures is analyzed, then pattern matching system is used to realize pattern matching and sleep position recognition. The recognition rate of sleeping position in the NISS is 95.6%, and the recognition rate in ISS mode is 92.5%. The recognition method proposed in this paper does not interfere with the user’s normal sleep experience. Combining the existing technology and methods to optimize the recognition of sleeping posture, the recognition rate of sleeping posture is still very high,which can help people with poor sleep to greatly optimize the sleep quality.
