A Software Product Line (SPL) that aims to develop context aware applications leaves challenges inherent to the SPL-based development approach and the type of application being developed (contextaware). These challenges leave open issues, like those related to how the context influences should be described. In the literature, there are studies that support the development of traditional SPL by ...

In this paper, we describe an innovative project where Web technologies are exploited to foster science learning in an integrated but mobile smart learning environment. Contextawareness is considered a crucial skill in science learning, therefore we imagined a solution to train students for context awareness by illustrating context gaps based on on-site observations and measurements. A componen...

Context-awareness is considered as an enabling technology and a rich area of application. This paper aims in monitoring and reporting critical health conditions of a patient who is suffering from brain tumor. We have built our ontology starting from knowledge gathering of data and reasoning to identify the health condition of the patient. So this has led to move towards to build an abstract fra...

Achievement of museum guide systems, in physical and virtual worlds, providing the personalization and context awareness features requires the prior analysis and identification of visitors’ behaviors. This paper analyzes and synthesizes visitors’ behaviors in museums and art galleries by using our defined parameters. A visit time and a observation distance can be calculated by using the propose...

Context information can add more meaning and value to the sensor data in Internet of Things. However, due to the large amount of sources of contexts and sensor data, the exchange of contexts through the networks may cause more and more data traffic. This paper proposes a novel method for maintaining and exchanging contexts through the Internet more efficiently. Contexts are classified into diff...

Since the context plays a significant role in ubiquitous computing environment, many researches have studied about context-awareness system to improve the performance. An efficient learning mechanism is in importance of context-aware system, but there are seldom algorithms focused on convenience of systems by elaborating the learning mechanism with user's context information. As one of the most...

Studies on the learning service selection approaches have been the subject of many researches in recent years. The works identified in the literature are developed to solve the learning service selection problem; however, these works need to have a clear view and an overview of how systems intended select services. This study details a multidimensional descriptive view of learning service selec...

Does the use of a wearable context-aware computer increase task proficiency? User trials have been carried out in an attempt to answer this question. The study involves WECAPC software developed to run on the χ wearable computer. The trials demonstrate that a wearable computer with simple context-awareness yields superior performance to either Internet search or realworld activity. Thus, we con...

A new approach for the realization of self-adaptive and highly available production systems based on a context aware approach, allowing selfadaptation of flexible manufacturing processes in production systems and effective knowledge sharing to support maintenance, is presented. The usage of dynamically changing context as basis for adaptation of flexible manufacturing lines/processes and effect...

Currently, the mobility of users who carry mobile devices and access resources through wireless networks brings up the need of providing uniform and immediate access to their information. In this scenario, a new model of education called ubiquitous learning is being explored. Therefore, the educational processes are related to the situation involving the learner (i.e., they are context-aware), ...
