For many applications the relevant context is limited in both size and scope. However there is an emerging class of applications whose context may include a huge amount of entities possibly dispersed over the entire globe. Those applications, including logistics, production systems, traffic control or energy management, rely on highly dynamic context information that is captured by a huge number of networked sensors and potentially shared by a wide spectrum of applications. Due to the distributed nature as well as the varying dynamics and quality of context information, scalable context management becomes a challenging task. In this talk we give an overview on context management and present some approaches to increase scalability. Finally, we will discuss future research directions in that field.","PeriodicalId":209341,"journal":{"name":"Annual IEEE International Conference on Pervasive Computing and Communications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122563506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The amount of interruption that have to be made on the users primary task should be minimized. Usage without interruption is of course best for the performance of the primary task but is often not possible as many tasks that the wearable computer is involved in do need interaction with the user. It is therefore important to understand what type of interruption that will benefit the user most. The question about which interruption that causes the least amount of stress for the user is as important as which interruption that gives the best performance. This paper continues on previous work where performance of the users was measured for different types of interruption. In this paper subjective data is analyzed to understand how to build user interfaces for wearable computers and head mounted displays that considers stress and other subjective variables","PeriodicalId":209341,"journal":{"name":"Annual IEEE International Conference on Pervasive Computing and Communications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132513684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Campbell","doi":"10.1109/PERCOM.2005.12","DOIUrl":"https://doi.org/10.1109/PERCOM.2005.12","url":null,"abstract":"The confluence of pervasive computing, anywhere/anytime access to information resources and scalable computing enables the construction of smart environments or Active Spaces. In such a Space, a spectrum of computation and communication devices seamlessly augment human thought and activity with digital information, processing, and analysis to provide an observed or imagined world that is automated and enhanced by the behavioral context of its users. The power of such a computer infrastructure has three contributing factors; the translation of information to and from physical properties, the computers and their ability to transform data, and the cooperative computational environment that results from embedding these devices in a network. This computational environment or “Active World” is the likely long-term benefit of the current information technology revolution. Several major projects have shown the benefits of considering pervasive computing environments within an infrastructure, constructed from computing elements that interact to form active or smart spaces, and managed by a software control system or meta-operating system to provide integrity and consistency. As a case study, our experimental system, Gaia, creates a pervasive computing environment that encompasses multiple rooms of our new building: the Siebel Center. Tasks like tours, exhibitions, seminars, lectures, or meetings are supported by coordinated distributed applications and both tasks and their contents may be programmed. Mobile users within the building are tracked with location sensors and may create sessions involving different tasks which they then may migrate, suspend, or resume as they move from room to room. Despite recent advances, many challenges remain. Integrating the various services, components, applications, and entities into a programmable COTS infrastructure enables context sensitive applications that allow users to interact seamlessly with a combination of physical and computer facilities. Such an infrastructure of smart devices, rooms, and buildings raises the question of how to manage, program, automate, and formalize these heterogeneous sources, sinks, repositories, and processors of data. The organization, management, and programmability of physical devices and information activities in a pervasive computing environment is key to enabling diverse, autonomic, digital habitats such as university campuses, office buildings, scientific labs, and museums. However, the promise of pervasive computing cannot be realized without cost-effective and efficient mechanisms, policies, and tools to organize, manage, operate, repair, program, and evaluate systems built from pervasive computing components. Human tasks, human factors and pervasive system infrastructure interact in complex ways and methodologies need to be devised to explore and measure these interactions. In particular, a pervasive environment would need to enable opportunistic collaboration, facilitate soci","PeriodicalId":209341,"journal":{"name":"Annual IEEE International Conference on Pervasive Computing and Communications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123766913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A record of the panel discussion was not made available for publication as part of the conference proceedings. Pervasive healthcare systems have the potential to revolutionize next generation medical applications and significantly improve the quality of healthcare services. In recent years, significant progress has been made in the development of a number of sensing and monitoring healthcare devices for clinical applications ranging from managing chronic diseases and acute diabetes to epilepsy and other debilitating neurological disorders. These wearable devices enable continuous monitoring of physiological signs as opposed to occasional episodic reviews with doctors and healthcare staff. More recently a growing interest in smart, implantable in vivo monitoring and intervention devices is starting to emerge. While progress is being made in the technologies associated with micro-sensing and actuation, issues related to the development of an information and computation infrastructure for the acquisition, fusion and dissemination of multi-sensory date and the development of power-efficient, QoS-aware protocols and mechanisms, for dependable, robust and secure wireless monitoring systems are still to be investigated. This panel focuses on discussing the long-term, challenging research problems and technological barriers that need to be addressed in order to enable a ubiquitous computing and communications infrastructure for large-scale, pervasive healthcare. Panelists from leading technology companies and research institutions will present brief talks centering on different aspects of the pervasive healthcare infrastructure. The audience will then be encouraged to ask questions and present short opinions.","PeriodicalId":209341,"journal":{"name":"Annual IEEE International Conference on Pervasive Computing and Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126686875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its emergence represents an unprecedented opportunity to expand the power of the Internet beyond traditional computing devices, enabling a world of smart spaces and smart appliances providing often invisible support for a variety of context-aware services with tremendous environmental and social benefits. Recent advances in wireless sensor technologies, coupled with the increasing capabilities of mobile and embedded computing devices, has triggered a rapid surge of interest in a variety of critical services, raging from pervasive healthcare and habitat monitoring to critical infrastructure protection and object tracking. It is clear, however, that the need for trust in the decision making ability of the pervasive system is paramount for its success. The objective of this panel is to address issues related to trust in pervasive computing environments. In this context, trust goes beyond traditional security concerns, namely privacy, confidentiality, information integrity, service availability, authorization and authentication. The focus will be on gaining better understanding of the notion of trust in pervasive computing, understanding the psycho-sociological aspects of trust, and discussing frameworks and models for trust establishment, dynamics and evolution. Panelists from leading technology companies and research institutions will present brief talks centering on different aspects of the pervasive healthcare infrastructure.

Broadcasting is particularly suitable for environments having a large number of clients. In this paper, we study the query processing of some typical location-dependent queries, such as window queries and kNN queries, in a broadcast system. To reduce clients' power consumption and provide efficient services, a transformation of the objects is applied based on Hilbert curve. Furthermore, a linear index structure is constructed and several algorithms are devised to answer spatial queries. Experiments are conducted to evaluate the performance of the proposed transformation and related algorithms. Results show that the proposed schemes outperform existing algorithms significantly.","PeriodicalId":209341,"journal":{"name":"Annual IEEE International Conference on Pervasive Computing and Communications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134004060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
