Several learning technologies have been developed over the years in order to help distance learning process. However, those technologies are still not enough to give the proper interaction between their users and the technologies themselves. It is caused by the absence of the technologies ability to give context based on their users conditions. When human interacts with each other, they understand...
In the era of pervasive and ubiquituous computing, the scope of computer applications is no longer restricted to traditional data processing. Pervasiveness and ubiquity imply that environment is a significant factor in computation. Context is an abstraction of environmental elements that has influence in defining the behavior of an application. Context-aware computing has been developing rapidly in...
An “everyware world” as Adam Greenfield calls it, is a world in which computers are embedded and merged seamlessly everywhere with the environment. Radio frequency and data identification communicates their position and other location information constantly in a vast file network. Everyday objects become searchable if they are part of interconnected World Wide Web. Looking into last three decades,...
Information and Communication Technologies have changed the way people live and work. Today, in the education field, there are a variety of education systems supporting innovative methods of learning and many universities are investing in creating their own eLearning Environments. Besides, learners' disabilities and learning difficulties still an issue, people can learn easily and deliver better outcomes...
Semantic exceptions mean undesirable contexts with respect to application semantics in context aware systems. Description of such semantic exceptions is based on regular expressions, which entails high complexity to detect exceptions. In this paper we devise an intermediate language for semantic exceptions of context aware applications. By bridging the gap between high level programming languages...
With the rapid development of the information technology, it is inevitable that the distributed mobile computing will evolve to the pervasive computing gradually whose final goal is fusing the information space composed of computers with the physical space in which the people are working and living in. Therefore, pervasive applications need a middleware that can detect and act upon any context changes...
Traditionally, context-aware applications are developed using one of the following approaches: each application communicates directly with sources of context information; applications are developed with the aid of reusable libraries for processing context information or applications have their own context models. These approaches not only require effort on the part of those who develop them, but also...
With the increasing use of 3D displays and input devices we need to be sure that when 3D worlds are created that their users can easily learn how to operate within these 3D worlds. To do this we can provide the user with a contextal interaction support within the environment. Within virtual worlds where you are free to move around and especially when you are immersed, trying to refer to a manual to...
We have reviewed the research of context awareness of recent years in this paper. First of all, we describe the definitions of context and context awareness which are made by different scholars in different fields, and propose our own definition. In addition, different classifications of context and context awareness are analyzed. We focus on context acquisition and sensing, context modeling and representation,...
Pervasive computing (also referred to as ubiquitous computing or ambient intelligence) aims to create environments where computers are invisibly and seamlessly integrated and connected into our everyday environment. Pervasive computing applications are often interaction transparent, context aware, and experience capture and reuse capable. Interaction transparency means that the human user is not aware...
In fast growing world we are in need of information for place we are in right now. For these types of services the Pervasive Computing is used. In Olden days, if we need some information means, we have to go to our computer and had the necessary information. Nowadays we have our laptop Computer with us and have the information where ever we are now. The sub domain of Pervasive Computing is Context...
The Internet is going mobile, and indications are that the mobile Internet will be ??bigger?? than the conventional Internet. Due to aspects such as user mobility, much more diverse use situations, and the form factor of mobile devices, context awareness is important on the mobile Internet. Focusing on geo-spatial context awareness, this talk covers research that aims to build infrastructure for mobile...
In this article we highlight and discuss prominent aspects of context and adaptively in pervasive computing environments along with characteristics and categories of context, and context-aware systems. We also briefly refer to use, management and modeling of context in context-aware systems. This paper is not meant to provide an exhaustive review of literature but rather it aims to integrate and extend...
