One of the primary issues in pervasive computing is the adaptation of the communication to the needs of limited devices. Web services are one of the technologies that present both big challenges and big potentials when it comes to their adapted usage in pervasive systems, because they carry communication overhead in order to support interoperability and platform-independence through self-description...
Empowered smart objects have become a part of people everyday activities due to the evolution of pervasive computing technologies. In such scenario context awareness plays a fundamental role in enabling adaptation and contextual services. Up to now a lot of efforts have been done in representing context information such as location, time and users identity. At the same time not much attention has...
Context-aware applications do not always adapt their behaviours in ways that users expect due to a variety of reasons. Applications that lack intelligibility are often incapable of offering explanations to users as to why they decided to adapt their behaviours in certain ways, and providing feedback mechanisms for users to take control of any unwanted adaptation. This can lead to loss of user trust,...
Cyber foraging is a pervasive computing technique where small, mobile devices offload resource intensive work to stronger, nearby surrogate computers in order to preserve energy and achieve better performance. The problem with relying only on local resources is, that the availability of such resources may be scarce in many environments. In this paper we therefore argue that a third tier should be...
The following topics are dealt with: pervasive computing; communications workshops; information quality; quality of service; ubiquitous communications; ubiquitous services; pervasive communities; service clouds; sensor networks; middleware; system support; social networking; security; context modeling; context reasoning; mobile peer-to-peer computing; pervasive collaboration; pervasive learning; pervasive...
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...
Social networks represent a sophisticated tool for accessing the preferences and properties of individuals and groups. Thus, they potentially allow up-to-date, richly annotated contextual data to be acquired as a side effect of users' everyday use of services. In this paper, we explore how such “social sensing” could be integrated into pervasive systems. We frame and survey the possible approaches...
Future pervasive computing scenarios will be characterized by an increasing diversity and dynamics of services and of contextual data sources, and by an increasing exploitation of crowdsourcing for social sensing and human computation. Accordingly, the role of middleware should no longer be limited to facilitating interactions and compositions via discovery and orchestration, but should approach that...
Pervasive computing technologies can enable very flexible situated collaboration patterns among citizens and, via crowdsourcing, can promote a participatory way of contributing to the wealth and quality of life of our urban environments. This position paper firstly sketches a future vision of pervasive computing rich and crowdsourcing-enabled urban environments. Then, it presents several case studies...
City-scale human mobility analysis is an important problem in pervasive computing. In this paper, with qualitative and quantitative analysis, we establish and confirm the relationship between the get-on/off characteristics of taxi passengers and the social function of city regions. We find that get-on/off amount in a region can depict the social activity dynamics in that area, i.e. the temporal variation...
Safety is a major challenge in developing assistive software for people with special needs in smart houses. INOVUS is an ongoing project about safety issues of cooking activities. This paper presents the INOVUS project and highlights lacks in current software development processes to meet safety requirements in pervasive computing. In the INOVUS project, we propose an approach to introduce model checking...
Pervasive computing refers to a seamless and invisible computing environment in which ubiquitous and connected computing devices gather information about the environment. Such computer-enabled artefacts represent a new category of smart products where objects are aware of their surroundings and cable of supporting users in various tasks. However, the complex and dynamic domain of smart products is...
This paper presents current work on a pervasive health and fitness game (exergame), designed to motivate children to reach their recommended daily exercise goals and facilitate long term behavioural change. I discuss briefly the current work in the area of pervasive exergames and highlight a common theme in the approach they take. Through my study of the relevant psychology literature, I identify...
Smart objects are gradually integrating into people's everyday life. While many context-aware solutions for pervasive computing environments do not consider users social aspects, we believe smart objects should be social-aware. So Smart aims at filling the gap in social understanding of the user environment, presenting an ontology based context model to support social context representation and automated...
