Increased availability of wearable devices, smart phones establishes a platform for designing innovative distributed crowd sourcing mobile applications. These applications can take advantage of computation offloading to augment the constrained resources and unavailability of required context on single mobile device. ContextMete is an offloading architecture that execute such applications across the...
Nowadays, as mobile smart terminals are becoming increasing widespread and multitudinous sensors are included, the applications with various new functions that run on mobile terminals are largely expanded. This paper proposes a Cross-Platform and Context-Awareness (CPCA) middleware intended for application developers, by which they can develop context-aware applications by providing the context reasoning...
Emerging technologies like mobile and wireless communication are offering promising opportunities to enable mobile healthcare delivery to citizens. But, enhancing the quality of service of such systems demands systematic improvement of existing service infrastructure. In this paper, we describe a context information refinement architecture proposed to address the shortcomings of existing works in...
The analysis of some context-aware services, in which the central element comes to be the user and its mobile device plunged in a rich and heterogeneous sensing environment, has driven us to face the design of context-aware systems as a multisensor data fusion process. In this paper we propose a fusion framework that describes the information flows and identifies the necessary functional blocks to...
Over the past 20 years, a lot of effort has gone into making the vision of ubiquitous computing a reality. A major focus of this effort has been on the understanding of human activity as input to enable the design and implementation of context-aware applications. Context-awareness is a vital enabling technology for ubiquitous virtual reality applications. However, it is only recently that we have...
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...
Computing technology is radically changing the manner in which we work and communicate with computers. ubiquitous virtual reality (U-VR) has been researched in order to apply the concept of virtual reality and its technology into ubiquitous computing. In this paper, we analyze past research on ubiquitous virtual reality and find future research direction.
Information privacy is usually concerned with the confidentiality of personally identifiable information (PII), such as electronic medical records. Nowadays, Web services are used to support different applications which may contain PII, such as healthcare applications. Thus, the information access control mechanism for Web services must be embedded into privacy-enhancing technologies. Further as application...
