A goal-oriented requirements engineering approach for the ambient assisted living domain

The Ambient Assisted Living (AAL) domain is associated with a large number of stakeholders such as patients, their relatives, caregivers and physicians. This variety introduces a great heterogeneity in system requirements, which sometimes results in conflicting needs that must be considered when developing effective AAL systems. In this work we adopt a Goal-Oriented Requirements Engineering (GORE) approach to map out needs and requirements for the AAL domain. Following the requirements mapping, we also propose a preliminary architecture for a home care system (named e-Ward) to assist patients in their domestic environment as if they are in a hospital room.
