Achieving Adaptive Augmented Reality through Ontological Context-Awareness applied to AAL Scenarios

This paper presents a proposal for supporting daily user needs by simple interactions with the environment through an augmented-reality perspective that applies proactive adaptation through knowledge representation using ontologies. the proposed architecture (i-ara) uses principles of the semantic web that endow context-awareness and user personalization. in addition, these types of services allow the supervision and management of what is happening in the environment and, consequently, improve the information offered to users. the architecture has been used to implement applications using iphone technology and has been applied to illustrative scenarios, including ambient assisted living.
