Abstract

In this thesis, the problem of improving accuracy of detecting and tracking human motion using wearable sensors has been investigated. The study focuses on understanding movements disorders such as slowness of gait and freezing of gait for patients with Parkinson’s Disease. Adaptive fractal analysis is applied to interpret the time series data to distinguish healthy subjects and the subjects with PD and the movements from PD patients with or without freeze. This study used different analysis tools such as phase, hurst exponent and power spectral density to study the time series data to differentiate different activities. The features of the data sets is investigated by applying principal component analysis (PCA) and high frequency occurred features to reduce feature dimension. The estimation results were further evaluated with and without cross validation.
