“…In addition, a real-time bio-feedback mechanism for postural correction and prevention is presented, and results from a pilot study show its effectiveness in reducing the amount of time subjects spend in FHP. [7] This research monitors the posture of a person's neck and converted the user neck's posture into 3D geometrical view. The system used Least Squares Orthogonal Distance Fitting (LSODF) to measure the user neck's posture in 3D geometry.…”

Technology has been playing a vital role in day-to-day life of the mankind. Eventually, it has also made a serious impact on the society by affecting the health condition of the people. A recent research proves that nearly 71% of the people community has been affected by the neck pain. The major factor for this impact is the long term usage of the mobiles or computers. As we are forced in an environment where we work for a very large time focusing upon a single position, there is risk of getting neck pain. To mitigate this problem, we proposed a sys-tem which alerts the user by tracking the neck movements. The sensor will be placed at the back of the user's head to determine the neck movements since the neck muscles are attached with the head. For detecting the neck movement, we have used MEMS SENSOR which can determine the variations in 3600degree. This sensor will be interfaced with the system via USB Cable through the arduino board. An alert message will be popped-out on the screen by the system to notify the user if the system finds slight variations in the neck movement. The data collected from sensor through data logging process will be sent to the registered mail of the user at the time of authentication. The sug-gestions will also be displayed as a pop-up message to reduce the strain. We have achieved approximately 93% accuracy, during testing process.

Neck pain and other spine related injuries are on the rise. One potential cause is bad head posture while using digital devices. We present two systems to monitor and improve head posture for two of the common problematic cases: laptop and mobile phone use. The laptop system uses the front-facing camera. The mobile system the sensor data of a smart glasses prototype. Both systems work reasonable in an initial user study with 10 and 8 participants (72 % detection on the laptop system, 100% for the mobile one). From the discussion, it seems users are especially interested in the smart glasses based monitoring implementation.

“…Fortunately, clinical practice has shown that early abnormal cervical curvature can be corrected through cervical spine posture monitoring and therapeutic intervention, with the process being more effective the earlier it begins [14][15][16] . However, current efforts to address this issue typically rely on either 1) expensive motion capture systems in a laboratory setting or 2) rigid and discrete devices that trigger audio-visual feedback on a smartphone or computer, which may not be practical or convenient for users to monitor and prevent cervical curvature abnormalities [16][17][18][19][20][21][22][23][24][25][26][27] .…”

“…Therefore, prior research has also explored using magnetic and inertial measurement units such as accelerometers, gyroscopes, or magnetometers to monitor neck posture [20][21][22][23][24][28][29][30] . Breen et al 28 built a system by placing a single accelerometer module at the C7 vertebrae for neck posture monitoring and correction.…”

Cervical spondylosis is a common disease that is often caused by long-term abnormal cervical curvature due to activities such as reading books and using computers or smartphones. This paper explores building an untethered and skin-integrated device in an e-skin form factor to monitor and haptically correct neck posture. The proposed design features a multilayered structure that integrates all flexible electronic circuits and components into a compact skin space while being untethered and skin conformal. An accelerometer in the e-skin attaches to the neck for posture sensing, while four vibration actuators closely touch the neck skin to provide localized vibrotactile stimuli that encode four-direction correction cues of neck flexion $$\pm \alpha$$ ± α and lateral bending $$\pm \beta$$ ± β . To ensure the reliability of posture sensing and vibrotactile rendering during neck movement, it is necessary to prevent the e-skin device from shifting position. Thus, a hollow structure-based method is implemented for stably attaching the e-skin to the neck skin. Experiments validated the e-skin device’s sensing precision, skin-conformal compliance, stickiness, stability and effectiveness during the motion of neck postures, including its discrimination of localized four-direction vibrotactile cues. A user study verified the device’s performance for sensing and correcting different abnormal neck postures during activities such as using smartphones, reading books, and processing computer files. The proposed e-skin device may create opportunities for more convenient cervical spondylosis prevention and rehabilitation.
