Unhealthy life habits are associated with a large number of chronic conditions in our modern lifestyle. Many commercialized wearable solutions have already been developed for monitoring and prevention purposes, while recent design efforts aim for more user-friendly and reliable solutions. In this context, due to the increased periods of sitting at work or home, improper sitting posture is related to numerous health disorders of the musculoskeletal system. Therefore, continuous stance monitoring can be used to improve users’ sitting habits. In this article, we present an overview of wearable self-care devices and describe a monitoring system for a sitting posture that utilizes wireless motion sensors attached to the user's back. The developed prototype relies on inertial measurement units able to track the angle deviation from the optimal position which is learned during a training phase. Additionally, in order to support stance visualization and track the user's performance over time, our framework utilizes a cloud-native mobile application. The proposed system is experimentally evaluated resulting in an accurate everyday solution that prevents chronic improper posture.

可穿戴式智能健康顾问：启用IMU的姿势监控器

不健康的生活习惯与我们现代生活方式中的大量慢性病有关。已经开发出许多用于监视和预防目的的商业化可穿戴解决方案，而最近的设计工作旨在提供更加用户友好和可靠的解决方案。在这种情况下，由于在工作或在家中坐着的时间增加，不适当的坐姿与肌肉骨骼系统的许多健康疾病有关。因此，连续的姿势监测可用于改善用户的坐姿。在本文中，我们概述了可穿戴式自我保健设备，并描述了一种坐姿监视系统，该系统利用了附着在用户背部的无线运动传感器。开发的原型依赖于惯性测量单元，该惯性测量单元能够跟踪在训练阶段学习到的最佳位置的角度偏差。此外，为了支持姿势可视化并随着时间的推移跟踪用户的表现，我们的框架利用了云本地移动应用程序。所提议的系统经过实验评估，得出了可以防止长期不当姿势的准确的日常解决方案。
