AB  - Wearable sensors are emerging trend and can be found in various application areas, including healthcare and home care, where they can provide important information about wellbeing, condition and activities of user and his/her behavior. Long-term data analysis can contribute by identification or even prediction of possible diagnosis or threat and for such reason, walking speed and hip extension angle can be useful tools for long-term based behavioral analysis. This article deals with evaluation of method for walking speed estimation and assessment of feasibility of accelerometer for hip extension angle monitoring. While proposed method for walking speed estimation has some limitations, it tends to be reliable. On the other hand, accelerometer for observing hip extension angle is not suitable due to the fact that when it is subject of translational movement, random error it introduced into measurement.
