<h3 style='margin:5px 0 20px'>Text from the patent</h3> [0001]Embodiments of the present disclosure relate tomonitoring exercise posture, and more particularly to a system and method to monitoran exercise postureof at least one user.<br /> <br /> [0002]Physical exercise is any kind of bodily activity which enhances or maintains physical fitness and overall wellness of a body. Further, modern technologies provide an interactive platform for enhancing the physical exercise of a user with the help of multimedia. <br /> <br /> [0003]In one approach, a system is implemented on an exercise mat to guide a user’sperformanceof exercises on the exercise mat. The system provides graphicalillustrations on the exercise mat for the user to perform the exercise based on the graphicalillustrations providedby the system on the exercise mat. However, in such system the exercisedone by the user is not monitored andhence the user is notguided. Also, the graphicalillustration may end up confusing the user to perform the exercise.Further, such system may also intrude the privacy of the user. Also, in such system, the existing mat has to be discarded in order to make use of such a system. <br /> <br /> [0004]In another approach, making useof the modern technology a system to detect the posture of theuser is built, wherein the system uses a plurality of pressure sensors which is fabricated on a substrate layer which is further imposed on the exercise mat. The system detects the amount of pressure applied by the user on the exercise mat and compares the applied pressure with a pre-defined pressure gradient. However, in such system the contact of the user with the exercise mat is not detected accurately and hence fails to detect if the user is performing the exercise in an exact way in which the exercisehas to be performedor not. Further the system uses a single layerof substrateto fabricate the plurality of sensors which may lead to high power consumption and high leakage current in the substrate layer. Further, the system does not detect and measurethe angle or position of the body of the user while performing the exercisewhen the user is not in contact with the exercise mat.<br /> <br /> [0005]Hence, there is a need for an improvedsystem and method to monitoran exercise postureof at least one user.
