The development of a wearable biofeedback trainer to increase quality of sitting posture

Abstract

In this paper, we design wearable devices that can monitor and provide voice and vibration feedback have been developed to change poor sitting positions. Abnormal posture has been shown to cause functional impairment in quality of life. This symptom is caused by the activity of sitting in a hunched position that is too long for years, thus permanently changing the shape of the back and the deterioration of joint function in the spine of the back. Previous research has been conducted on wearable devices to monitor the slope angle of the spine. but the system is still fairly simple because the system used is not directly integrated with media monitoring. In this study developed wearable devices using biofeedback trainer techniques to change bad habits when sitting in a hunched position so that the tool will provide a feedback to rearrange the position of the body by force into an upright position and the system will be integrated with the mobile application using Bluetooth. The results show that this wearable device can measure the slope angle of 0° to 90° with an average error of 0.42° and can improve the quality of sitting posture.
