Kenji Kashima, R. Nakamura, A. Kajiwara · 2013
In this paper, a bathroom movements monitoring sensor system based on Ultra-Wideband Radio (UWB-IR) is suggested where a Cube Higher-order Local Auto-Correlation (CHLAC) method is employed to estimate some movements of a bathing person against waving from the surface of water in a bathtub. The usefulness of our suggested algorithm is investigated experimentally and it is shown that estimation rate of more than 90% can be attained for various a bathing persons movements in a bathroom.
