BACKGROUND
Due to long-term use of computers and not maintaining the correct position and angle of the body while working with it, various skeletal and muscular problems and pain in the neck area occurs. This study aims to use a biofeedbck system to alert the computer users of an inappropriate angle of their necks, and as a result help them to establish a correct neck position.
METHOD
The user's neck angle is measured using a three dimensional accelerometer and the signal is processed, digitalized, and sent to the computer. User friendly software is designed to process the received data and warn the users when their neck angle is inappropriate.
RESULTS
The results show that the application of the biofeedback system reduces the users' total time with inappropriate neck angle to <50%.
CONCLUSION
results demonstrated that training with the biofeedback system has been sufficient to make the habit of maintaining the neck in the correct angle.
背景
由于长期使用电脑且在使用时未保持正确的身体姿势和角度，会出现各种骨骼和肌肉问题以及颈部疼痛。本研究旨在使用生物反馈系统提醒电脑用户其颈部角度不当，从而帮助他们建立正确的颈部姿势。
方法
使用三维加速度计测量用户的颈部角度，并对信号进行处理、数字化，然后发送到计算机。设计了用户友好型软件来处理接收到的数据，并在用户颈部角度不当时发出警告。
结果
结果表明，生物反馈系统的应用将用户颈部角度不当的总时间减少至<50%。
结论
结果表明，使用生物反馈系统进行训练足以使保持颈部正确角度成为一种习惯。
