From the user interaction point of view, any IP-enabled device, such as the latest smart phones and tablets, can be used as user interfaces of the system, and it is possible to build alternative interfaces that access directly the Logic Unit without interference to the existing ones. This allows the system to be easily adapted to each person's needs with minimal or no change in the system.
Taking advantage of the information collected with the system, a Quality of Life Evaluation Service has been developed. The QoLE system uses artificial intelligence to detect routine changes in the kitchen and to inform whenever there are changes in behavior patterns. This allows progressive personalization of the system and early intervention of the carers when loss of abilities of the user is identified.
The evaluation with real users and their carers demonstrated that the system developed has the adequate functionalities and user interfaces as it is physically, sensory and cognitively accessible and usable for the elderly and disabled. We have found evidence that this system would prolong the time elderly and disabled people could remain independent in their own homes, thereby positively impacting their quality of life, although longer studies with larger user groups would be needed to confirm this
