Abstract:The improper sitting posture of reading and writing can have a serious effect on the health and learning efficiency of the young. This study designed a new type of portable, real-time monitoring, and intelligent reminder system of the writing and the reading sitting posture. According to the biomechanics and ergonomics rules, the system uses 40 cm×40 cm flexible force-sensitive sensors to collect sitting pressure distribution data, combined with environmental parameters to analyze results in real time. Meanwhile, the sitting position and environment change are displayed during the monitoring period in real time via the mobile phone APP. The system is easy to understand and interactive, which can help teenagers to correct improper sitting postures. With the convenience of mobile phone, it is convenient for users to achieve real-time warning and analysis.
