This work it is a PhD project that aims to develop the communication pedagogical model of u-learning Youubi with the adequacy of pedagogical models to favor the effectiveness of learning through the use of ubiquitous technology. The work related to this issue highlights the difficulties of the adequacy of pedagogical models that incorporates the ubiquitous computing resources in the educational context...
Advances in computer networking combined with powerful home computers and modern operating systems made streaming media practical and affordable for ordinary consumers. We are enjoying different streaming services such as DMB, PMP, smart phone, etc. that have never experienced before. In the future computing environment such as ubiquitous environment, user can be served video streaming service by...
In this paper we define an ontological model to accurately represent the context in Pervasive Computer Supported Collaborative Work. A major issue in this domain is the mass of information required to correctly depict a situation. As we need to represent users and devices according to multiple aspects (physical, computational, social ...) the amount of information can quickly become unmanageable....
Interactions between people occur in a social realm. On the other hand, “things”, including devices for communication and computation, are generally socially deficient. Imagine socially aware systems moving from an interruption model of communication to an introduction model. To create considerate systems, there is a need to model social context, social behavior, and communication goals. This paper...
Context-aware computing is an emerging computing paradigm that provides intelligent context-aware application. Its core idea is to have computers understand the real world so that human-computer interactions can happen at a much higher abstraction level, hence to make the interactions much more pleasant or transparent to human users. Context-awareness is the key to achieve this goal. It entails a...
Our social life is characterised by norms that manifest as attitudinal and behavioural uniformities among people. With greater awareness about our social context, we can interact more efficiently. Any theory or account of human interaction that fails to include social concepts could be suggested to lack a critical element. This paper identifies social concepts that need to be supported by future context-aware...
In a dynamic heterogeneous environment, such as pervasive computing, context-aware adaptation is a key concept to meet the varying requirements of different clients. However, this newfound versatility poses difficult challenges for user-interface design. The traditional UI development measures seem insufficient toward this situation. As the concept of design pattern in architecture and software engineering,...
Service process usually needs to be changed during reuse because of the change of context. These change mapping relations provide additional information to help users customize service processes. In this paper, we present a mining approach to mining process change sequences based on different context and finding the best sequence to tailor the base process.
In the paper, it refers to the concepts of ontology, OWL and context, different context information is defined by the tuple method, and establishes the model of context-awareness based on ontology in Smart-Home, and then it introduces the model of reasoning and memory in detail; and studies the affections of ontology on the two models. At last, the paper explains the application of model by using...
In this paper, we propose a sensor-based interaction for ubiquitous virtual reality (U-VR) systems that users are able to interact implicitly or explicitly with through a sensor. Due to the advances in sensor technology, we can utilize sensory data as a means of user interactions. To show the feasibility of the proposed method, we extend the Composar augmented reality (AR) authoring tool to add support...
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...
The seamless combining with context-aware sensors and numerous devices and e-home server will soon become a part of our home environment in the near future. We name it as a context-aware home based on ubiquitous computing concept. This context-aware home reduces participations of users in order to realize a ubiquitous computing and automates various services. Therefore, the risk of privacy violation...
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.
Pervasive and ubiquitous computing have the potential to make huge changes in the ways that we will learn, throughout our lives. This paper presents a vision for the lifelong user model as a first class citizen, existing independently of any single application and controlled by the learner. The paper argues that this is a critical foundation for a vision of personalised lifelong learning as well as...
