Today's ubiquitous wireless networks enable easy access to information on the web. However, when applications need access to highly transient and hyper-localized information, web access is not as efficient as sharing directly with colocated devices. This context information can be easily collected by commodity mobile devices and shared via device-to-device interactions. Open challenges remain in making...
Energy efficient building refers to building with an integrated system that is aware toward energy usage and has an effort to automatically reduce all electrical energy wasting by turning some unused devices off. In order to decide an appropriate decision, such a system needs surrounding contexts, such as location and activity that are obtained from sensors around the environment. We propose a novel...
The main goal of pervasive computing is to provide services that can be used by the user in the given context with minimal user intervention. To support such an environment services or the applications in the environment should be able to interact seamlessly, with the other devices or applications present in the environment, to gather relevant information in current context. Main challenge is devices...
This position paper introduces and discusses Social Object Labels, small pervasive displays for ubiquitous social object annotation. Taking an HCI perspective, it relates user experience problems with ubiquitous annotation described in the literature to a lack of dynamic information available to users and argues that small pervasive displays can address these problems by providing dynamic situated...
Nowadays, advertisers and content publishers are constantly struggling to find the best advertising strategies to promote their services. They need to be able to reach the target population that is potentially interested in their products or services, without being too tiresome, and to deliver the content properly in order to capture users' attention. In this paper we describe a system that uses pervasive...
There are so many interactions in pervasive computing environments that should be done automatically. Sometimes even users don't know about some interactions that are done in his/her devices. It refers to a concept based on a vision described by Mark Weiser. “The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable...
There is increased demand to run applications on mobile devices in recent years. Although many of these alluring applications are resource-intensive, they expect to get the same performance on mobile devices as on powerful non-mobile computers. On the other hand, considerations such as weight, size, and mobility impose constraints on mobile devices and restrict their processor speed, memory size and...
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...
This paper looks at a case of team-oriented endurance sports. Like most current human activities, it already comprises an existing pattern of co-ordination based on technology, namely the mobile phone. It is clearly a limited technology for the purpose of supporting swimming, biking and running, such as in our case of triathlon racing. Can we identify an alternative, dedicated and equally good technology...
Recent rapid advancement in both pervasive mobile computing and cloud service has been driving numerous new applications in the ubiquitous media consumption. To provide mobile user with richer experiences, it is desired for the service providers to offer highly relevant recommendations of media content to the users by exploring user-user, user-media and user-context relationships. Furthermore, contemporary...
A challenge in the convergence of heterogeneous networks is how to combine the ubiquitous resources and provide the diversified individual services. 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 of wireless personal area and wide area networks...
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...
The pervasiveness of mobile devices and short-range wireless networks deployed in urban areas have brought Weiser's vision of ubiquitous or pervasive computing into reality. The mobile devices weave themselves into urban dwellers' lives as an undetachable part. In urban places, there are not only people but also their devices' presence. Interestingly, devices can communicate wirelessly with each other...
Ubiquitous computing has gained momentum over the last years with the expansion of mobile devices. One area of pervasive computing is context-aware systems which are applications designed to react to the constant changes in the environment. This paper presents a context aware platform that handles context acquiring, processing and service provisioning management. The platform alleviates the process...
We report an investigation into the communication needs of working parents pertaining to awareness of each other's whereabouts and activities. Twenty working parents took part in an experience sampling study for a period of one week and in follow up interviews. Analysis of participant responses shows that working parents can benefit from automatically updated information relating to availability of...
We present a semantic context management framework named Context Torrent, which can make various types of context information be semantically searchable and sharable among local and remote context-aware applications. We implement this framework on the Google Android platform with its elegant application support. An open source RDF parser has been extended to effectively get RDF triples from files...
With the emergence of pervasive computing environments, mobile information sharing and retrieval is becoming an exciting domain that challenges information scientists. In this paper, we describe a hybrid peer to peer context-aware framework for building mobile information sharing applications. A scalable and flexible architecture based on JXTA is presented. The architecture called "JHPeer"...
Recent research in pervasive computing has shown that context-awareness and dynamic adaptation are fundamental requirements of mobile distributed applications. However, most approaches that focus on context-aware dynamic adaptation use only the context information available at the mobile device to trigger a local adaptation. However, for distributed collaborative applications this is clearly insufficient,...
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...
