Push notification is an important approach to distribute interesting information to users timely. With the fast development of mobile devices and mobile applications, push notification is getting more and more popular. The convergence of mobile and IoT also bring new challenges on how the system can handle the mixed push channels designed for M2M communication and human interaction, and enable the...
The use of mobile devices as data service providers is on the rise. Mobile devices feature a large set of distinct characteristics that qualify them to be the most convenient computing platform for online services, both as consumers and providers. Mobile devices can take advantage of their mobility to provide location-based services and their association to a specific user to customize service offerings...
In daily life, people have to perform a large number of activities typically in a limited amount of time. Accordingly, they may benefit from help and guidance provided by support systems in order to accomplish these activities accurately and in the correct order. In order to satisfy such needs we develop a software framework which also incorporates a mobile application. Within the framework, workflows...
This paper proposes a framework for a professional context-aware mobile learning system. This system provides learning contents delivered via mobile devices and adapted to learning needs, personal characteristics and particular circumstances. Supported by this system, professionals will acquire personalized, just-in-time and problem-based learning contents in real working situations.
We consider the decision engine of mobile cloud offloading systems, which decides whether to offload a given method to the cloud servers. We design, implement, and evaluate a context-aware decision algorithm, called CADA, to optimize the performance of the mobile devices with various optimization criteria, including short response time and low energy consumption. The CADA algorithm can work with various...
Along the last decade, organizations have developed BPM (Business Process Management) as a methodology to manage their own Business Processes, with a consequent evolution in the involved systems. Different technical issues such as high availability and growing connectivity, and also economical aspects generated by development and maintenance costs have guided a big number of organizations to choose...
With the development of wireless networks and mobile computing, more advanced applications with context-awareness and adaptability to their changing contexts are needed. In this paper, a context-aware middleware for user experience improvement in mobile payment has been developed. Using NFC(Near Field Communication) and fast face recognition system on mobile phone which is developed based on improved...
Using mobile devices for learning gets more and more popular. However, in order to provide learners with suitable learning materials in such mobile settings, the learners' characteristics and context should be considered. In this paper, we propose an approach for providing personalized course content in mobile settings, considering a combination of students' learning styles and context. The proposed...
This paper presents an architecture proposal for mobile services. It covers server-side and terminal-side components for the easy creation, provision and consumption of mobile services. The intrinsic characteristics of mobile services are reflected in this approach. Especially the role of the power user, that not only consumes mobile services but also modifies them or creates services of his own,...
The traditional techniques developed to deal with the issues in business process improvement don't meet the current and future organizations requirements. The existing methods are technology/fixed business process centric and not user-centric. The systems that can recognize the context of the user can bring great benefits especially enabling businesses to run more efficiently from any location. In...
This paper briefly presents our Information Retrieval and Indexing System (IRIS), and how it adapts to support game engine components. We describe a conceptual game, Chasers of the Lost Data, to demonstrate how pervasive games elements interact with content and user context detection, enabling a broad range of game applications. The presented game combines physical, sensorial and contextual information...
The increasing processing power, storage and support of multiple network interfaces are promising the mobile devices to host services and participate in service discovery network. A few efforts have been taken to facilitate provisioning mobile Web services. However they have not addressed the issue about how to host heavy-duty services on mobile devices with limited computing resources in terms of...
Map services help people find places they wish to visit. Users input the target address and the system returns that location on a map, with additional information such as nearby points of interest, directions to the location, etc. However, these applications mainly focus on general knowledge, failing to provide personalized information that may help users find/identify a place faster. In this paper,...
One issue for context-aware applications is to identify without delay situations requiring reactions. The identification of these situations is computed from both dynamic context information and domain specific knowledge. This identification is the output of a process involving context interpretation, aggregation and deduction. In smart environments, these treatments have to be efficient since they...
Ubiquitous computing envisions applications that provide seamless and distraction-free support for everyday tasks. To achieve this goal, applications must be able to adapt to their environment and to the intents of their users. Thereby, they need to automate adaptation decisions to minimize the resulting distraction. As a consequence, it is necessary to acquire an understanding of the user’s current...
Empowered by mobile computing, teachers and students can benefit from computing in more scenarios beyond the traditional computer classroom. But because of the much diversity of device specification, learning contents, and mobile context existing today, the learners get a bad learning experience (e. g. rich contents can not be displayed correctly) during u-Learning environment. This paper proposes...
Context-aware ubiquitous computing applications thrive in extremely dynamic and heterogeneous environments. When they are delivered to the user preconfigured and without the capability to be adapted, they may fail to satisfy the user's changing needs and may give the user the feeling that control is taken away from him. In this paper we present how context can be exploited in ubiquitous computing...
Efficient collaboration and task management is challenging in distributed, dynamically-formed organizations such as ad hoc disaster response teams. Ineffective collaboration may result in poor performance and loss of life. In this paper, we present Overseer, an open multi-agent system that leverages context information in a mobile setting to facilitate collaboration and task allocation. We describe...
Users want to access user generated content and recommendations in a contextualized way while on the move. In this paper we illustrate the POI radar service and its architecture, a mobile mashup of integrated location, social network and users' recommendations to provide contextualized notifications of nearby points of interest voted by user's contacts. A description of the service scenario, architecture...
