Context awareness is one of the major research areas of pervasive computing. Several proposals for the design of context aware applications rely on a closed feedback loop that performs four phases. Monitoring and collecting context (phase 1), analyzing the collected context to detect changes (phase 2), deciding adaptation actions related to the changes (phase 3) and performing and executing the corresponding...
Nowadays we can see a new era of mobile computing springing up. Mobile devices more often than not provide incomparably more relevant information and context about their users than was ever available on desktops or within classic web browsing. With this a new branch of research for autonomous software is forming. The aim is to recognize usage situations to let an application decide on performing a...
For the ubiquitous computing environment, an important assumption is that all the components in any specific environment are connected with each other. With this assumption, we introduce an effective scheme to provide a personalized service based on Virtual Personal World(VPW). Virtual Personal World (VPW) which is a model focused on service continuity of personal world. Previous ubiquitous frameworks...
As we all know, the World Wide Web is becoming a large source of images. Thus, it is manifest that the demand for image recommendation systems is increasing rapidly. There are several image recommendation systems for both commercial and academic areas, which deals with the user preference being fixed. However, since the Images preferred by a user may change depending on the contexts, the conventional...
With the advent of ubiquitous computing environments it has become increasingly important for applications to take full advantage of Context aware computing to increase the satisfaction of the users in entertainment services. The contextual information, such as, environmental, social, task, Spatio-temporal and personal information has to be considered to offer greater services to the user without...
Context-awareness refers to computing systems that are able to sense and to comprehend their environment in order to adapt themselves in dependence to the available and relevant contextual information they depend upon. Gathering such contextual information involves real world entities such as sensors, which, for various reasons, are often prone to certain degrees of uncertainty and inaccuracy. Nevertheless,...
Context management systems allow services and application easy access to remote dynamic context elements, in turns allow these to adapt to the users context. The fact that most information is dynamic and changes value over time, leads to potential risk of obtaining information mismatching the true value due to the communication delay. The probability for this we call the mismatch probability. Obtaining...
