Results demonstrate the feasibility of implementing an accelerometry-based, real-time movement classifier using embedded intelligence.
Accelerometry: providing an integrated, practical method for long-term, ambulatory monitoring of human movement.
An integrated approach is described in which a single, waist-mounted accelerometry system is used to monitor a range of different parameters of human movement in an unsupervised setting.
