Collaborative decision-making is one of the emphasized student skills required by educators from different domains including science, technology and society. Multi-surface environments (MSE) appear particularly well suited for such learning activities, with large shared surfaces dedicated to the overview of information and context awareness, while personal surfaces serve browsing and analytical...

The success of personal information agents depends on their capacity to both identify relevant information for users and proactively recommend context-relevant information. In this paper, we propose an approach to enable proactive context-aware recommendation based on the knowledge of both user interests and browsing patterns. The proposed approach analyzes the browsing behavior of users to der...

This study primarily exploits a context-awareness and personalization model supporting ubiquitous learning log system. Learning log stands for the log of knowledge or learning experience acquired ubiquitously. The model has three main behaviors, which are to recommend learning objects in accordance with both learners’ needs and contexts, to detect their learning styles using the context history...

Respecting the mobile world, it is about the time to demand for systems to fully take advantage of their environment. In this way, Enhanced Sensor Network is another step toward developing realistic context-aware applications, which is based on the basic infrastructures provided by wireless sensor networks (WSN) and those proposed by context-aware application development paradigms. In this pape...

With the development of wireless communication and portable devices, people can now enjoy the benefits of mobile computing. But due to the nature and design of portable devices, it is unlikely portable devices can provide certain functionalities with the same quality as fixed devices. So during mobile computing, it is not trivial to attain computing within a fixed network environment with high-...

Many context aware systems assume that the context information they use is highly accurate. In reality, however, perfect and reliable context information is hard if not impossible to obtain. Several researchers have therefore argued that proper feedback such as monitor and control mechanisms have to be employed in order to make context aware systems applicable and useable in scenarios of realis...

Context awareness is a vital element in pervasive and ubiquitous systems. While most existing research has focused on designing context-aware systems to integrate into the environment, less attention has been placed on the interoperability among the entities comprising such systems. In this paper, we consider how the components of a context-aware system can collaborate to achieve a common goal....

In our everyday life, we communicate with each other within a certain context; our actions are also within a certain context. Events affect every aspect of human life. The importance of the context also influences how we interact with the environment and how technologies provide services for us. The Context is generally regarded as data or information which describes the situation that is relev...

Context-aware systems are applications that adapt to several situations involving user, network, data, hardware and the application itself. Researchers in context-awareness have concentrated on how to capture context data and to carry it to the application. In this paper, we study the impact of context on the core of the application. First, we give the guidelines of a context model based on a m...
