Abstract

In earlier studies, we have developed activity recognition algorithm which are based on features calculated from 3D accelerometer sensor data placed on a hip, close to the centre of mass. In the development subjects have been young adults. Now we study are the input features of the algorithm generalized for older adults and for different sensor placement; in this case worn as a necklace. From the 3D accelerometer resultant magnitude the following features were calculated for each second: spectral entropy, peak frequency, power and range. The frequency domain features behaved in a relatively stable manner in the set-ups but the time domain features differed significantly from statistical and algorithm perspective between the set-ups. By developing time domain features to be more inter-individual independent would be beneficial for activity recognition algorithms
