This work describes several infrastructure contributions targeted to enhance the interaction with Ambient Assisted Living-AAL [1] environments, so that elderly people can maximize the time they live independently, through the help of Information and Communication Technologies-ICT at their homes. Traditional interaction mechanisms, such as the keyboard, mouse or the usage of tactile screens to interact with the environment are only suitable for elderly people with ICT familiarity, but they are not friendly enough for most of the elderly that have never interacted with this kind of interfaces. That is the reason why this work proposes a set of multimodal interaction alternatives with the environment combining more natural communication channels like voice, images, videos and non-intrusive sensors and devices which interact by themselves, in an implicit manner, with the environment.
