Recent environmental control systems, designed and developed according to Ambient Assisted Living paradigm, can increase the chances of active and independent living for elderly people and people with disabilities, by improving their safety and autonomy. Such systems can play an assistive role, interacting with users through non-invasive smart-sensors, monitoring their wellbeing and implementing behavioural analysis. This paper aims to present some tools developed into the CARDEA AAL system to foster a more effective transfer of AAL outcome to caregiving practices. By processing raw data generated from low-cost environmental sensors, CARDEA allows for the identification of behavioural “trends”, which can be meaningful to caregivers. Presentation tools are proposed, suitable for highlighting relevant issues, the actual interpretation of which is left to the caregiver.
