Dynamic Efficiency Analysis of the Accelerometers Spatial Orientation Influence Elimination Method during Human Activity Using Semi-movable Accelerometer Mounting

The study reviews a solution to the problem of exclusion of accelerometers spatial orientation influence on the results of physical activity evaluation. Methods are suggested how to select a constant for recording the three-axial linear sensor data, whose application is reviewed for the case of the sensor rigid fixation and its non-rigid fixation. The analysis of the obtained results allows to talk of applicability of the developed method in case of active free movements in the process of monitoring a human functional condition within 15% interval of acceleration constant change.
