Real–world movement analysis in health, ageing and disease using body worn sensors: from step counting to 3D motion tracking
Sensors such as the accelerometer have been widely used over the last 30 years for activity monitoring, mainly as actimeters for step counting. More recently, the field has taken giant leaps forward through the use of wearable inertial sensors. These sensors extend the movement monitoring and analysis palette offered by lab motion capture techniques to real-world conditions. Advanced and powerful algorithms could be devised for 3D tracking of body movement by combining biomechanical knowledge with multi-sensory information such as acceleration, angular velocity, elevation, location, force and pressure. This makes wearable sensors ideal tools for long-term monitoring of daily activity. In my talk, apart from touching upon the above aspects, I will focus on methods and advanced algorithms used in real-world conditions for gait analysis, activity monitoring, and sport performance evaluation. By emphasizing the translational aspect of wearable technology in health and disease, my talk aims at demonstrating the potential and maturity of wearable inertial sensors to fulfill clinical needs.
