Smart Wearable Posture Trainer and Corrector System using BLE

Abstract

In this smartphone era, millions of people are suffering from back-pain, text-neck and rounded upper back conditions all around the world. The most common reason behind this is poor posture of the back and neck. Poor posture while sitting and standing is commonly found in students and heavy computer users. To correct their poor postures and to prevent back pains, they need training to maintain good posture. Poor posture may lead to irreversible pathological changes in spine and may even cause paralysis. However, early stage training with device like ours can improve their lifestyle. We found the need of an electronic device in the market, so we are proposing a posture correcting device that is ready to wear as a necklace and smart enough to be controlled via a smartphone. The system has two modes of operation, offline mode and online mode. In offline mode, the alert in case of poor posture is done by the vibrator motor attached to the back of the user. In online mode, device communicates with the smartphone and notifies via a push message or alarm through an android app. This system has small size and low power consumption due to BLE (Bluetooth low energy device) and can be used for long time. We have classified the neck postures and cervical curvatures into seven and four different positions, using our first prototype. It was developed with mercury tilt sensor in its core. Here in this advanced project we use tri-axis accelerometer for more efficient functioning. Finally, we ought to develop an android based application to support and communicate with the user. Providing real-time status monitoring and health tips.
