  Ireland Responsibilities • Investigate the use of inertial measurement units to classify movement exercises performed during rehabilitation following knee and hip replacement. Use a minimal number of body worn sensors to determine if the prescribed exercises were performed correctly and if not, what movement deviations were performed. • Developing the techniques and approaches of signal processing and data mining • Using data mining tools to analyse the big data, including stream data •… Show more Responsibilities • Investigate the use of inertial measurement units to classify movement exercises performed during rehabilitation following knee and hip replacement.
