The quest to transform the television viewing experience into a digital media service is happening thanks to the addition of companion screens to the TV. Multi-device experiences become more intuitive and easier to use federating cooperative devices. They also bring new creative opportunities to schedule and distribute interactive content synchronised with the TV programme through any connected screen...
Emerging context frameworks enable Websites to interact with the Internet of Things directly from the browser; however, Websites must be specifically designed to utilize such context framework support. As such, the majority of “legacy” Websites remains context-unaware. This paper presents Ambient Amp, an open framework for dynamically augmenting legacy Websites with context-awareness, without requiring...
In this paper we present CLIO an urban computing system used to form and interact with the collective city memory, formed by shared citizens' recollections. Our goal has been to study the impact of such a system on the urban culture and in particular how it alters the city, the perception of people about the city and the communication among people. We applied CLIO and conducted user studies in two...
An important feature of the intelligent environments is that they monitor user activities and help them in making decisions based on their progress in activities. Many such environments have been designed previously for healthcare management. However, more than often users are reluctant to consider the feedback from the environment alone. So we consider expert's recommendations and social network...
Crowdsourcing has emerged as a new learning and online collaborative paradigm, in which “crowds” of people can collaborate and complete a specific task. In this paper, we provide a survey of crowdsourcing as a means of collaboration in three different contexts, namely academic, enterprise, and social. The survey also includes a short inventory of how different factors contribute to the development...
Content usage statistics from superdistribution users have great commercial values since they can be used for any number of purposes including marketing, accounting, and/or fraud prevention. However tracking content usage under the superdistribution model poses a great challenge since most content users have no explicit pre-established relationship with the content provider. In this paper, we present...
Internet video services have experienced an immense popularity in the recent years and will probably be the dominant applications of Future Internet. Therefore, the design of scalable video distribution systems that on the one hand, improve the end-users experience and deal with theirs context heterogeneity and on the other hand, optimize the cost of these services, is becoming a very important and...
In this research, we present a system that can support object gestures in ubiquitous environment. We propose various techniques to use any object around users for devices and appliances interactions. These techniques make user interactions more natural and intuitive. We propose technique to use any object around users for devices and appliances interactions. These techniques make user interactions...
Users often become frustrated when they are unable to understand and control a pervasive computing environment. Previous studies have shown that allowing users to pose why and why not questions about context-aware applications resulted in better understanding and stronger feelings of trust. Although why and why not questions have been used before to aid in debugging and to clarify graphical user interfaces,...
In this paper, we propose a web-based Japanese mimicry and onomatopoeia learning assistant system (JAMIOLAS). In our previous studies, we have proposed context-aware language learning assistant systems that used wearable sensor and sensor network respectively, and attended good results. In order to use this learning model in broader area and more general scene, we are trying to realize the system...
This paper addresses the challenge of enabling efficient multimedia group communications in today's highly heterogeneous networking environment. In particular, such an environment calls for a multiparty delivery solution capable of finding an optimal balance between two apparently contradictory needs: on one hand personalizing the service delivery for each user based on his particular context to offer...
Context-awareness involved in e-learning includes awareness to knowledge context, awareness to social context, and awareness to technical context. This study proposes the use of context-awareness for personalized learning content recommendation in e-learning environments, and discusses the key steps in the recommendation mechanism.
Content adaptation is an attractive and effective solution to resolve the mismatch of resources and properties between the delivery context and the multimedia content in heterogeneous environments. The problem with multimedia content adaptation is that there is no a single complete software solution that can satisfy all types of required adaptation needs. In order to solve this problem adaptation...
Service-oriented multimedia processing system is an effective approach to allow dynamic and customized service requests in a pervasive environment. This paper studies the context-aware multimedia processing problem under the consideration of the QoS from two aspects: delay and media quality. The second metric is introduced based on the factor that different display devices can adapt to different media...
The paper look into the use of a personal smart phone as a main controlling entity for personal communication (using IM, audio or video) in an office environment. The service PPCom (personal pervasive communication) is a kind of `Follow-Me' service. This paper presents the architecture and the design. The architecture is based on a clear separation of `call' and `connection' according to NGN. The...
Service composition is an effective approach for large- scale multimedia delivery. One of the challenge issues is how to choose services to build a multimedia delivery path from source to destination based on user's requirements. In previous works, user's requirement is represented as one fixed functional path which is composed of several functional components in a certain order. Actually, there may...
Under the development of ubiquitous technologies, people need a novel media system. That means the multi-sensory media service which satisfies the five senses and makes people feel realistic. It is necessary to build knowledge about sensory effects and devices in order to provide the service. In this paper, we propose an ontology-based knowledge modeling. The proposed ontology model consists of effect...
Evolving device capabilities and network technologies make the seamless combination of personal area and wide area networks capable and desirable to exploit advantages of each of the environments. By this, the vision of adaptive and context-aware service provision becomes possible and offers new opportunities for pervasive computing. In this paper, we describe an approach that addresses the convergence...
