Experiment result analysis (algorithm performance)   <ul><li>Conclusions: </li></ul><ul><ul><li>The final BMR algorithm deviation is within range of 10% compared to reference CWT (using stop watch), the algorithm performance fulfills the potential clinical rehabilitation quality assessment requirement. </li></ul></ul><ul><ul><li>The BMR algorithm reaches comparable performance range as initial benchmark device ActivPAL3, which is mounted at a much better position for steps detection. (ActivPaL3: UpperLeg, BMR: Belt at the Hip) </li></ul></ul><ul><ul><li>MicRoberts’ MiniMod has problem while detecting extreme slow walking speed (down to 1.4 km/h = 0.4 m/s), because of worse mounting position compared to ActivPAL3. </li></ul></ul><ul><ul><li>BMR system has online processing algorithm (fixed point computation) while MiniMod system uses offline processing mode. </li></ul></ul><ul><ul><li>The main error source is from test persons’ transition pattern and mis-classification into locomotion class in standing and sitting cases. </li></ul></ul>
