Incorrect anatomic habits cause incorrect anatomic postures which take long time to get corrected with ordinary methods, also to prevent, there are methods based on ergonomics. The method which we devised is based on biofeedback method with ergonomic considerations. Up to now the ergonomic designs have been according to biomechanical statistical data which can be unsuitable for those whose biomechanical data has great deviation from mean state, but our mobile device uses individual biomechanical data, detected from target limbs. In this paper first the principles and real–time the architecture of the project is defined and explained, then sensory and optimization phase will be stated and finally the project’s results and future will be discussed.<\div>

In this paper after a brief review on previous studies on above knee prosthesis design, SEP prosthesis which has recently introduced considered. This prosthesis has modeled with fixed and moving ankle separately during the swing phase of walking and the optimized physical parameters have been discussed. Here it is tried to compare the results of these models and survey the effects of the improvement of segmentation in behavior and the resulted optimized parameters of the models. The comparison of models in the amount and the pattern of actuation torque, damping torque and inertial effects represent that, this improvement in segmentation results in reduction in the amount of all of the considered physical parameters which is appreciated.<\div>

In this paper after reviewing the history of biomechanical researches on biped movement, in order to achieve a deep insight on the structure and biomechanics of human body, capability of proposed simple models in predicting ground reaction force (GRF) pattern has been investigated and finally an optimized inverted double pendulum with compliant joints is suggested. The results for GRF pattern during single stance phase for this model were incredibly satisfactory. Beside the great potentials of inverted double pendulum with compliant joints model in explaining the double peak appearance of vertical GRF, it also follows well the kinematical behavior of human leg during single stance phase. These results can be applied vastly in optimizing biped robots and also can be used in other fields like biomechanics, kinesiology and rehabilitation technology.<\div>

In this paper after reviewing some previous studies, in order to improve our previous modeling of above kneeprosthesis comprises SEP controlling parameter, moving ankle assumption is considered. SEP controlling parameter makes the prosthesis able to act as a multi behavior system when the amputee is opposing to different environments. This active prosthesis with the new controlling parameter can simplify the control of prosthesis and reduce the rate of energy consumption in comparison to recently presented similarprosthesis Agonist–antagonist active knee prosthesis . In this paper three models are generated; a simple passive, an active, and an optimized active prosthesis. The optimization procedure is genetic algorithm. The SEP controlling prosthesis model with moving ankle during the swing phase represents acceptable results in comparison to natural behavior of shank and the fixed ankle model. Reported results in this paper represent 3.2 degrees as the maximum deviation of optimized model shank angle from the natural pattern. The natural gaitpattern belongs to walking at the speed of 81 m\min.<\div>
