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

Numerous Ambient Assisted Living systems have been developed in the last decade, but there is still an evident lack of monitoring systems that are suitable for some of the specific user's activities. That is certainly the case with the ones related to the bathroom environment, where the strict respect of functional and privacy requirements are imposed. The paper proposes a monitoring system that is able to identify the bathroom activities taking into account requirements that an Ambient Assisted Living systems dedicated to older adults should satisfy. Proposed monitoring system consists of presence sensor, humidity sensor, and microphone-based sensor that provide autonomous and automated classification of different signals representing possible activities. Based on the sensors' data, an efficient reasoning module has been proposed, which is able to detect critical situations for user and home safety and to provide information for lifestyle pattern reasoning and daily function monitoring module.
