Guaranteeing ubiquity and appropriateness of security and monitoring services provision to the users constitutes a priority issue for the authorities. This paper presents an innovative Wireless Personal Area Network architecture that takes advantage of some of the features provided by Intelligent Environments -large number of devices, hetero- geneous networks and mobility enhancement- in order to adapt and per- sonalise ambient conditions to the user profile. This system is based on image processing and its main aim is to provide an AAL solution that is integrated with other control devices for the home to make everyday tasks easier for users. 1 Introduction The ageing of the population and, consequently, the growing of chronic diseases in a change in the way home services (i.e. monitoring, assisted living, emergency help) are provided. New technology developments could be a potential answer to the requirements of a society demanding better assistance [1]. Previous ex- periences urge for an improvement in human- machine interfaces enabling users (i.e. mostly elderly people, and disabled) to deal easily and non-intrusively with technology [2]. The latest innovations in this area come from the field of Ambi- ent Intelligence(AmI) [3]. New technologies, based on the design of easy to use and easy to learn devices that work transparently and pervasively [4], will help users overcome the current existing limitations. Traditionally, Smart Homes have been designed for the rich and famous. Devices such as door openers, activated by telephone, have not been considered for use within the care sector. Ambient Assistant Technology (the use of products or equipment, to help maintain or improve functional capabilities) has begun to be accepted by the care sector and as a result environmental control systems are being used. Smart Home technology uses the same basic devices used in Assistive Tech- nology to build an environment in which many features in the home are auto- mated and devices can communicate with each other. Smart Homes are often the ideal solution for individuals with differing levels of disabilities.
