Ambient Assisted Nutritional Advisor for elderly people living at home.

Nutrition is a critical aspect when getting older because bad nutrition habits can accelerate the process of degradation of the physical condition of the old person. In order to mitigate this problem, an Ambient Assisted Living service has been developed. Research with this service is focused on demonstrating that with an Ambient Intelligence systems it is possible to make the nutritional management much more effective by influencing the user, by automatically and seamlessly monitoring and by facilitating tools for nutritional management for people that want to be autonomous. In this paper both requirement acquisition and development processes are described as well.
