This chapter presents a hardware/software platform based on a state-of-the-art Time-of-Flight (ToF) sensor and a low-power embedded computing system for the automated recognition of body postures with applications ranging from detection of dangerous events (e.g. falls) to natural human-computer interaction (e.g. assistance during rehabilitation/training exercises). The platform meets typical requirements for Ambient Assisted Living (AAL) applications such as compactness, low-power consumption, noiseless, installation simplicity, etc. In order to accommodate several application scenarios, satisfying different requirements in terms of discrimination capabilities and processing speed, two feature extraction approaches are investigated (namely topological and volumetric) and related performances are compared. Discrimination capabilities of the two approaches are evaluated in a supervised context …
