A functional ARM movement tracking and monitoring system using electogoniometer

This paper presents a new sensing system on magnetic linear encoder (MLE), in which the motion of an magnetic encoder on a code strip is converted into the limb joints goniometric data. This project evaluated a non invasive technique for estimating the carrying angle in full extension using a 3-dimensional digitizer. The angle data is essential data for identifying abnormal patterns and characterizing impairments, disabilities and handicaps. The knee angle is measured with an electrogoniometer; angle of knee is controlled by PIC16F877A microcontroller. Capsense technique is used to giving input to the microcontroller PIC16F877A, information are displayed using 16*2 LCD display.
