可穿戴的智能矫姿系统设计与实现

Design and implementation of wearable intelligent posture correction system

针对长时间的坐姿不良对伏案人群的身体健康造成严重危害的问题,提出了矫正姿势和久坐提醒双管齐下的解决方案,设计了一套可穿戴的智能矫姿系统。通过对人体脊柱生理结构的分析,采用双惯性传感器协同采集的方式提高了数据采集精度。当系统监测到人体出现不良坐姿时,通过自动触发语音和震动提醒的方式辅助用户纠正当前不良坐姿。利用姿态检测技术,建立了基于动作状态变化的智能计时模型,改善了目前只能周期性计时提醒的方法。利用手机APP的数据可视化显示和相关参数设置,改善了系统的人机交互体验。测试表明:该系统具有矫正姿势效果良好和久坐提醒灵敏的特点,可有效缓解久坐带来的危害。

In order to solve the problem of serious health damage caused by poor sitting posture for a long time,a two-pronged solution of correcting posture and sedentary reminder is put forward,and a wearable intelligent posture correction system is designed.Through the analysis of the physiological structure of human spine,the data acquisition accuracy is improved by using double inertial sensor cooperative acquisition.When the bad sitting posture of the human body is monitored by the system,the voice and vibration reminders are triggered to reminder the user correct the current bad sitting posture.By using attitude detection technology,an intelligent timing model based on action state change is established,which improves the current method of only periodic reminders.The human-computer interaction experience of the system can be improved by using the data visualization display and related parameter setting on the mobile phone APP.Finally,the system test shows that the system has the characteristics of good correction posture and sensitive sedentary reminder.It can effectively alleviate the harm caused by sedentary.
