Mobile context-aware computing is an essential component of the smart cities infrastructure. Attempts were made to develop a model that can effectively represent a system in device to support context-aware behavior. The purpose of this paper is to identify deficiencies of the previously developed model and propose solutions to improve it.
Ubiquitous Learning changing the existing paradigm of learning that is a learning process everywhere, every time and anything into the learning process right place, right time and the right thing, so that the determination of the appropriate content for the user and the system's ability to adapt to the user is important in ubiquitous learning. Context aware in ubiquitous learning can be used to achieve...
Existing research on implementing the mobile cloud computing paradigm is typically based on offloading demanding computation from mobile devices to cloud-based servers. A continuous, high quality connection to the cloud infrastructure is normally required, with frequent high-volume data transfer, which can have a detrimental impact on the user experience of the application or service. In this paper,...
The advancement of the Internet, mobile and wireless technologies have produced a rapid change of information in terms of volume and accessibility. The enormous volume of information can be devastating especially to mobile users exceeding human ability to differentiate information which is relevant and that which is irrelevant. For many years now, recommender system have become well-known, and have...
With the proliferation of mobile devices and the development of wireless technologies, users can run a wide range of applications on mobile devices. However, the mismatch between applications and mobile devices does not guarantee the application quality. To solve this problem, this paper proposes a context-aware application matching system.
The applications in Ubiquitous Computing (UbiComp) environments must be aware of their contexts of interest and adapt to changes in them. Thus, a major research challenge in the area of UbiComp is related to context awareness. Considering the high distribution, heterogeneity, dynamism, and mobility of ubiquitous environments, this paper presents an architecture for context awareness, named UbiC (Ubiquitous...
The increasing penetration rate of feature rich mobile devices such as smartphones and tablets in the global population has resulted in a large number of applications and services being created or modified to support mobile devices. Mobile cloud computing is a proposed paradigm to address the resource scarcity of mobile devices in the face of demand for more computing intensive tasks. Several approaches...
Context information, such as user location, time, and user profile, has been popularly applied to analyze user behavior for many societies . In this paper, we develop a restaurant recommendation system based on mobile context-aware services to provide customized information for users. We analyze the service satisfaction ratings of the users to recommend favored restaurants for them. With mobile context...
The paper presents an idea of a context-aware application, which collects context data from many different sources, stores them in a dedicated database and makes use of it to support flexible scenarios for end users. Using open APIs it integrates different types of context information provided by: Unified Communication system, APIs exposed by communication service providers and information from Machine...
With the rapid development of mobile cloud computing, the identity authentication has become more and more important. but most of the authentication methods were authenticating device rather than users. Context aware information, such as, operational context, personal context, spatial context, and environmental context, can provide users with their really needed services without any explicit requests...
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...
Context-aware service provisioning for mobile phones is challenging because of diverse user contexts and mobile applications. The context recognition process generally reduces the device performance due to the competitive use of limited resources in the mobile phone. While extensive attempts have been made to provide appropriate services based on user context, previous work is limited to supporting...
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'...
To provide effective mobile services in spite of network disruption, context aware middleware services on mobile devices and application servers can provide services for continuation of applications, by managing mobile services, network connection, limited resources, and context information. In this paper, we propose context aware middleware services for disconnection tolerant mobile application 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....
Learning does not only take place in a conventional classroom setting but also during everyday activities such as field trips. Such context sensitive learning is not new and can be observed in many different areas. The increasing availability of mobile devices and network access opens up new possibilities for providing context aware support for such learning scenarios. Related work focuses mainly...
The paper introduces an approach to automatically recognize people's activity patterns within an “intelligent” building. We envisage a model of interactions with a smart phone and building. Various sensors in smart phone enable to recognize daily routine of people's activities automatically in building. The smart phone application; `Activity Pattern Recognition in Mobile Environment (APRiME)' recognized...
In this paper, an acoustic and visual signal based context awareness system is proposed for a mobile application. The proposed system senses and determines, in real time, user contextual information, such as where the user is or what the user does, by processing signals from the microphone and the camera embedded in the mobile device. An initial implementation of the algorithms into a smart phone...
Thanks to the embedded sensors providing in mobile devices will revolutionize the way to carry out with. Mobile devices provide a set of embedded sensors, such as accelerometer, digital compass, gyroscope, GPS, microphone, and camera. Another point to consider, is that mobile devices are easily programmable since an API was included by the OS companies. This paper aims to describe a distributed architecture,...
In this paper, we propose a context-aware system framework characteristic of two novel features. First, this framework is capable of modeling highly complex usage scenarios as a finite state machine while having transitions controlled by context information. And, this framework is designed with Augmented Reality capability as an integral component in its overall architecture to enable augmented interaction...
