An Architecture to Support Personalized Interaction Across Multiple Digitally Augmented Spaces

Abstract

Any physical space can be augmented with digital information, associated to various locations or artefacts contained in it. In this paper, an abstract architecture is presented, supporting interaction with mobile context aware applications in public digitally augmented spaces. We focus on how this architecture supports personalization of interaction and adaptation. The main goal of the architecture is to allow users to benefit of a uniform and personalized experience across different contexts and spaces. Among the concerns are: to support high interoperability and flexibility and to address issues of privacy and user control. The framework has been tested in typical augmented spaces: a library and a museum. The paper concludes with a set of examples of use of the defined framework that cover typical situations for intra-space and across spaces usage.

An architecture to support design of context-aware mobile applications

“…As discussed in (Stoica & Avouris, 2010), in MobiAct there are two levels for providing personalization and adaptation: intra-space and across spaces. The key element is the User Agency that is a trusted entity which the user herself selects.…”

“…The answers are given on a scale from 1 to 7 were 1 is "not at all" and 7 "a lot". (Stoica & Avouris, 2010)) emphasizing personalization and adaptation (the flow of information between elements in the scenario is always device → user agency → broker → service providers and back, however we just highlight the parts that are of interest for the specific step, for the sake of clarity and brevity)…”
