This paper presents a new approach for hyperlocal data sharing and delivery on the base of discoverable Bluetooth nodes. Our approach allows customers to associate user-defined data with network nodes and use a special mobile application (context-aware browser) for presenting this information to mobile users in proximity. Alternatively, mobile services can request and share local data in M2M applications...
Nowadays health concerns are effectively becoming ubiquitous. Most people have the need to effectively control their nutritional consumptions, mostly due to health issues. Personal computational devices may assist this control with a solution that allows an efficient management of each individual nutritional profile.
Several studies both in the field of psychology and in the field of physiology relate stress to the difficulty of transferring information from short term memory to medium term memory. This difficulty causes a reduction in personal efficiency and generates heavy frustration as things to do tend to come to mind with no relation to the user current environment, thus further increasing the stress level...
Traditional phone communication is designed on the assumption that caller actively telephones callee without any knowledge of callee's situation. Caller often doesn't make successful calling as callee is not available at that time. Along with the development of pervasive computing and sensor technology, context information of user can be sensed, inferred from pervasive environment. Before starting...
We have established a multi-walker recognition/tracking testbed based on low-cost pyroelectrc sensor network (PSN). In order to identify a region of interest (Rol) in the monitoring area for the detection of any interesting mobile targets, we propose to use Bayesian machine learning and binary signal projection to extract the statistical contextual features from real-time, high-dimensional PSN data...
Context histories, especially when recorded over a long term, offer a wide range of possibilities to enhance the services provided by ubiquitous computing system application. These possibilities include inferring of current and past user location, and selection of devices. However, the prediction of future context based on the recorded past locations is often conceived as the ultimate challenge in...
This paper made an exposition of the mobile search servicing system's demand, architecture, main functions of components according to a case for searching a place of entertainment of a city. It specially elaborated on how to use mobile context and policy management to render web services for mobile web service middleware.
The explosive growth of location detection devices, wireless communications, and mobile databases has resulted in the realization of location based services. Unfortunately, current location based services are rigid as they are isolated from various concepts of contextual information which include not only user's location but also user's preference, user's plan, network connectivity, etc. In this paper...
Foreign students who live and study in China encounter many problems in Chinese language learning, as language learning often correlates with background knowledge which varies from country to country caused by cultural and social differences in terms of distinct public policies and services. With the increasing number of foreign students in China and the great demand for mobile Chinese language learning...
In order to provide context-aware services, context modeling is one of the most important tasks. Ontology has been widely accepted for the context modeling but it brings some overheads in the process of reasoning large-scale and dynamic information. In mobile networks, especially, ontology should be verified to be applicable for Context-aware Services since real-time responsiveness for large scale...
There are several radio access technologies providing connectivity for mobile devices. In the future, more and more mobile devices will be capable of supporting more than one access technology. For being able to use these technologies simultaneously, there is a need for multihoming capabilities. Due to the variety of access technologies and the ability to use them simultaneously, new concepts for...
Current learning systems are frequently criticized for their predominant focus on explicit, and in particular, written representation of knowledge. There are communities around the world where verbal knowledge is more pervasive than written knowledge. This paper presents a study of how such knowledge can be accessed anywhere/anytime, in a form that may be used and understood in a standardized format,...
Collaborative filtering technology is the key technology of recommendation system. However, collaborative filtering technology has been suffering from sparsity that it needs mass ratings from users to improve precision. In traditional e-commerce, asking users to rate on their own initiative will degrade experience of users, let alone the mobile business environment. So, both in e-commerce and m-commerce,...
The work describes SMARTMUSEUM ICT solution of personalized cultural heritage content access for mobile users. Addressed aspects include unifying user preferences, context information and respective annotation of content. Implemented real solution is described briefly.
In modern organizations, the communication between collaborators is essential to improve productivity. There is a need for mobile collaboration tools that allow efficient collaboration among staff in organization which may be located in different geographical areas and time zones. Mobile and pervasive computing provides easy and convenient access to information, enabling effective collaboration. This...
In many application fields such as disaster management or personal planning, efficient mobile services should capture users' context in order to provide them with the most appropriate information at a given time. Situation-based services aim towards this direction. They go beyond location-based services as they take a user's current situation into account. Situations include user profiles together...
As mobile smart phones are being equipped with multiple radio interfaces and sensors, they are becoming capable of continuously collecting context information related to the users and the environment. This information can be utilized in different applications and services for providing rich, context-aware experiences. In this paper, we present a client-server platform that enables life logging, via...
Although behavior modeling should play a central role in model-driven application development, it is still unclear how behavior modeling should be incorporated in model transformations. This paper presents an MDA-based approach that incorporates behavior modeling at the platform-independent model (PIM) level of the design process of a specific category of applications, i.e., context-aware mobile applications...
The ceaseless evolution of wireless communications is taking the shape of the so called 4G networks: Fundamentally different radio technologies coexist and cooperate to offer continuous connectivity to applications. Mobile devices are now equipped to take advantage of access media abundance to improve the user experience. However, traditional management techniques were quickly obsoleted by the spatial...
This paper considers the complexity of context in mobile Information systems. Personalization is considered with context, context-awareness, mobile systems, and related research including adaptation. The principal design issues are introduced with consideration of proposed solutions and open research questions. This paper posits that the current predominance of location-based context-aware applications...
