Looking for an Adequate Monitoring Mechanism for Rehabilitation Systems Based on Movement Interaction

Movement-based interaction has appeared as a key factor in taking a step forward in healthcare. Rehabilitation represents an appropriate domain in which to focus efforts. In this sense, the authors have developed SIVIRE, a system whose main contributions are a virtual online editor of exercises and the capacity to adapt rehabilitation to patients’ conditions and their evolution. During the development process, some aspects were studied in order to improve the quality and accuracy of the system, such as monitoring patient’s postures, which is a critical procedure in correction and guidance. Specifically, this paper presents an analysis of the monitoring technique the authors studied. Three mechanisms were analysed, thus addressing the approach differently: using joint coordinates, bone coordinates and the angles generated by bones. After the study, the authors discuss the reason for identifying the use of joint coordinates as the best technique to monitor patients in this kind of movementbased interaction techniques.
