The development process of a project requires verifications that may be handled through expert team. It means that a project cannot be completed in absence of the analysis phase. The analysis and measurement have the strongest reason to prove the accuracy of outcome of the project. As ubiquitous computing is the most probable era for current research, most researchers are working in the contextual...
This paper reports on a user study to gauge user interaction with RSS based mobile electronic updates from a Moodle based virtual learning environment. The electronic updates can be received in three dimensions of context: time, location and activity. The study aims to compare and evaluate the effectiveness of these context dimensions by comparing the level of user engagement. The mobile updates relate...
Privacy is the most often cited criticism of context awareness in pervasive environments. Context aware pervasive applications have the vulnerabilities of capturing extensive portions of users' activities. Whether such data capture is an actual threat or not, users' perceptions of such possibilities may discourage them from using many useful pervasive applications. So far, in context aware pervasive...
Context-aware computing is a new paradigm that relies on large amounts of data collected from a variety of sources, ranging from smartphones to sensors, to automatically take smart decisions. This usually leads to large volumes of data, that need to be further processed to derive higher-level context information. Clouds have recently emerged as interesting candidates to support the storage and aggregation...
In this paper, we propose a process calculus, Context-aware System Calculus (CSC), in order to describe context-aware systems that can maintain context models and carry out some operations, including requesting context-aware services, according to the context rules. Besides, a context-aware system can also communicate with other systems or receive context information from context providers by sharing...
This paper proposes a mobile application for retrieving electronic updates from virtual learning environments using dimensions of context. Using automatically generated RSS feeds from a Moodle based virtual learning environment, information can easily be delivered in a concise format through wireless networks directly to the student's device. The paper reports on a pilot study carried out to provide...
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...
The emergence of context-aware computing (CAC) environment makes context based human-computer interaction (HCI) possible. The main problems faced CAC is the lack of a unified, general support for CAC system framework. This paper proposed a smart space oriented context-aware system called S2CAS in order to provide an idea to handle contextual information processing and services.
The CUBIQ (Cross UBIQuitous platform) project is a national R&D project in Japan for establishing a multi-domain context-aware service platform from 2008 to 2010. It involves setting up a common service platform environment on which many sensors, devices, mobile phones and actuators can be universally handled and connected to ubiquitous networks even in the autonomous distributed environment....
Recent advances in mobile, wireless, and sensor technologies provide new possibilities for supporting learning activities that can be spatially distributed and incorporate different physical and environmental sensory data. In this paper, we present our technical efforts in relation to the design and implementation of mobile and web applications that integrate sensory data used to support inquiry-based...
