Integrating physical and information space into applications increases application's complexity and development difficulty. In Ubiquitous environment, context collection, aggregation and notification raise complex scientific problems and new challenges. In this paper we address these challenges by proposing a conceptual context-oriented middleware architecture. We first discuss the reason to use context...
Cars have become an increasingly important and exciting test bed for ubiquitous computing. However, smart car space is still little addressed in the literature to enable high adaptation in a mobile and resource-limited space. This paper focuses on building a context-aware software infrastructure for smart car space in middleware framework. To support context-awareness, we embed capabilities of context...
Ubiquitous environments provide families of context-aware applications that are capable of exploiting the user mobility as well as the device variability. Typically, these applications retrieve context information from local and remote providers and react accordingly to the detected variations. However, this must be done by considering the heterogeneity of devices and protocols found in ubiquitous...
This paper describes the Context Awareness Framework developed for the HYDRA Middleware Project. The HYDRA project aims to develop middleware to support intelligent networked embedded system based on a service-oriented architecture, deployable on both new and existing networks of distributed wireless and wired devices. A well developed Context Awareness Framework (CAF) is crucial for the success of...
Automotive software has increasingly become context-aware and adaptive to deal with dynamically changing environments. This paper presents our novel service-based approach to support the structural and behavioral adaptation of automotive telematics. We adopt services to (1) provide physical context facts and (2) facilitate context-aware interactions between entities of automotive telematics systems...
Incorporating service composition and pervasive computing into managing user's complex everyday activities envisions the paradigm of pervasive service composition for everyday life. Context-aware pervasive service composition (CAPSC) enables a pervasive system to provide a user with service compositions that are relevant to the user's context. Moreover, CAPSC enables composition applications that...
Pervasive applications are featured by their transient interactions, explicit surrounding contexts and by the flow of activities. Towards transparently tackling these features yet rigorously modelling and validating such applications, this contribution capitalizes on SE advances: (1) explicit separation of concerns (e.g. interaction-centric functionalities and context-awareness); (2) flexible description...
In ubiquitous computing environments, certain entities (or actors) often need to interact with each other in achieving a joint goal in a dynamically changing context. To perform such interactions in a seamless manner, the actors need to be aware of not only their physical context (e.g. location) but also their changing relationships with respect to the particular task or goal. The latter interaction-oriented...
In this paper, we study how to exploit the context-awareness in augmented reality (AR) applications to take advantage of the context in both the high-level and low-level processing. We propose an AR system architecture that works with a context-awareness framework. In the system, both the preliminary and the final context is provided to the process that needs the context. We provide two scenarios...
