Abstract

Abstract:

Sit recognition is of great significance to sit monitoring. In view of the problems of low accuracy, complex debugged and high cost of the existing sitting recognition device, a method of sitting posture recognition based on pressure sensor is introduced in this study. The method realizes the recognition of different sitting postures according to the difference of the pressure values of the pressure sensors at 8 monitoring positions on the upper body of the human body under different sitting postures. The test results show that the proposed method can identify four sitting positions, and under the same height, the pressure value is positively related to the weight. In the four sitting positions, the pressure values of the thoracic and lumbar vertebrae are significantly higher. These obtained results indicate that this method can be applied to sit sitting posture monitoring equipment, to realize the recognition and monitoring of sitting posture.

Key words: Arduino single chip microcomputer, pressure sensor, sitting posture research, sitting posture recognition, passive monitoring, test experiment, non-wearable, intelligent device
