A modelling framework for ambient assisted living validation

This paper describes a modeling framework that facilitates and streamlines the process of creation, design, construction and deployment of technological solutions in the context of AAL assuring that they are accessible and usable for senior citizens. The framework supports the design of the Human Interaction aspects of an AAL solution in all the stages of a user centered design methodology, putting in practice the guidelines for the verification and validation of the accessibility and usability facets. Two environments are defined: The authoring environment allow the definition of the user, environment and service models. The simulation environment is composed by software and hardware components that constitute a physical ensemble that in conjunction allow the ICT designer to implement actual Virtual Reality scenarios of AAL. It will be used to verify interaction designs and validate the accessibility of the AAL products by means of immersing the users in 3D virtual spaces.
