Automated algorithm for classification of water-flow signals to support Ambient Assisted Living applications

An example of monitoring system with reasoning module for ambient assisted living applications

“…This sensor contains microphone for data acquisition and on-chip processing unit. On-chip processing unit could be implemented based on algorithm for automated classification of water-flow signals proposed in [22]. As it is shown in [22], water-flow signals from the shower, the sink, and the toilet could be clearly distinguished.…”

“…However, their main drawback is massive deployment of environmental sensors which often require some adaptation works and significant costs. In order to provide functional, but costly acceptable solution, attention of the researchers was oriented toward monitoring through audio sensing and processing [19]- [22]. Monitoring systems in [19] and [20] are based on using low-cost microphone-based sensors mounted on water pipes for water-flow monitoring.…”

“…In our previous paper [22] the bathroom monitoring system with intelligent microphone-based sensor has been proposed. It was shown that water-flow signals from shower, sink, and toilet can be distinguished by using simple and low-cost microphone.…”

“…As a result of that analysis, assuming different bathroom's configurations and microphone-based sensor positions, automated decision making and classification algorithm has been developed. The system proposed in [22] is fast and could be efficiently used in AAL systems.…”

“…The last one has ability to perform signal processing algorithms and autonomous decision making and reasoning. Part of microphone-based sensor is presented in our previous paper [22]. In this paper we pay special attention to main challenges in designing bathroom activities monitoring and reasoning system that are: ethic, privacy, and security limitations and requirements that have to be carefully studied and addressed.…”
