Abstract : This paper proposes a new solution for an e-health system architecture related to personal assistance at home for aged people. This architecture takes into account the results of two ongoing projects on which the authors are involved: Sweet-Home and AmiHomeCare and the possibility of combining different parts of these projects in order to obtain a more versatile system. Each project has a distinctive way of gathering the required information: Sweet-Home uses sound processing, AmiHomeCare - video processing. The paper analyzes the advantages and drawbacks of both approaches in order to propose an integrative new architecture.
