CH-AVATAR is a context-aware platform for tourists and visitors of Cultural Heritage sites. Cultural Heritage objects (CH objects) become “alive” within the platform. They tell their stories and interact with tourists. The platform employs BLE beacons and the visitor's smartphone or tablet to create an interactive and adaptive Cultural Heritage experience for its end users. The paper makes a generic...
With the giddy growth of the amount of the information data through constant interaction and sharing in daily life, the mobile Internet has shifted from the lack of information to information overload. How to satisfy readers' individual needs from the disorder and mixture data has become an urgent problem to be solved. This paper combines the context information into the recommended process, and constructs...
Ubiquitous learning with context awareness uses contextual information to give a better service to users with a flexible and easy-to-manage way. Context awareness is able to provide suitable services to certain people. There are 10 context awareness parameters in ubiquitous learning; one of those parameters is strategic context. Strategic context is a plan that gives influence or impact towards the...
As applications deployed in a smart space share the same physical environment, they may interfere (or even conflict) with one another. To guarantee the performance and user experience of the entire smart space, mechanisms for handling such interferes (or conflicts) have to be introduced. We believe that conflicts among multiple applications are caused by their different requirements and impacts on...
The purpose of ubiquitous computing is to make computers and the environment integration as a whole. Pervasive Computing makes computer equipment that can sense changes in the surrounding environment, and ultimate the computer itself disappears from sight. In the pervasive computing environment at any time, place, people can be in any way acquisition and processing of information. With the development...
Web service compositions run in changing environment where different context events can arise to affect the execution of services. In order not to make service execution affected by context events, context-aware service composition becomes one of the major research trends. Service providers can develop context-aware services which can adapt their behaviors dynamically to execution contexts. However,...
In response to the challenges for application development, deployment, running and maintenance in an open, dynamic, difficult to control for Internet platform, the concept of Internetware came into being. It is a new software architecture, which is flexible to evolution, continuously reactive and adaptive to multiple targets. Software entities form a software web, which is similar to current information...
With rapid development of IOT (Internet of Things), the computing mode of the 21st century is undergoing profound reform. IOT's final goal is fusing the information space composed of computers with the physical space in which the people are working and living in. By this fusion, people can get information service transparently according to their personal needs whenever and wherever they are. However,...
To realize smart home services, several context-aware applications should be deployed which adapt their behavior depend on context information of home occupants. For context-aware service, context providing, processing, reasoning, delivery and designing context-aware applications are complex tasks. In this paper, we present a context-aware middleware which provides above tasks and supports context...
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...
Context-aware plays a pivotal role in the wisdom network of information processing. Due to the limited resources, context conflict is inevitable in context-aware. User satisfaction is a good reflection for the wisdom degree of the network. In this paper, considering the user satisfaction, we propose a novel context-aware conflict solution model based on set pair Analysis (SPA). The model obtains the...
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...
Nowadays, as mobile smart terminals are becoming increasing widespread and multitudinous sensors are included, the applications with various new functions that run on mobile terminals are largely expanded. This paper proposes a Cross-Platform and Context-Awareness (CPCA) middleware intended for application developers, by which they can develop context-aware applications by providing the context reasoning...
Human-computer interface of turret currently is not friendly enough because of the mobility, styles of input and output limitations and computing ability. But contexts of human-computer interaction are not considered comprehensive in the process interface design. Therefore, it's vital for the operational efficiency to import a way of human-computer interaction for interface based on context-aware,...
Recently, context aware has become a popular topic in ubiquitous computing. Most context-aware research combines embedded system devices with context-aware systems to realize a ubiquitous environment. This study proposes a Daily Exercise Context Aware Ontology Model (DEOCAM) and builds a Context Aware Exercise System (CAES), which is free of space limitation. CAES is composed of three parts: Personal...
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...
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. To achieve this goal, one of the problems is how to continuously monitor/capture and interpret the...
currently the context models focus more on the expression ability rather on the automatic deployment and execution capability. Also a context aware platform is required to support the modeling and automatic deployment and execution of the context aware system. This paper aims to build an executable context model and define the architecture of the context aware system as well. Firstly a context-aware...
Workflow model has been successfully applied to the traditional computing environment. Currently, there are many studies trying to apply workflow to ubiquitous computing environment. In ubiquitous computing environment, a service must be based on the user's context information to be executed. Now, however, there is no workflow system has a pervasive computing environment to support context-aware services...
The modern mobile ubiquitous computing environment, with reasonable connectivity, processing power and sensing capabilities on portable devices, present applications and services with the opportunity to be truly context-aware. But building context-aware applications has large development overheads due to complexities of sensing, aggregating and inferencing context information. To reduce the developers'...
