CSCW Systems on PvC Environments

CSCW is a well-suited discipline for appropriate communicating ideas inside a group and even in an inter-group cooperation. Though basic technology for communication annoy people with too many computer-related tasks to deliver at-the-time elaborated notes in the meanwhile of a group activity. An emerging trend that promises to bring a solution on this matter is that of ubiquitous, or pervasive computing. PvC is about computation becoming part of the environment with the ambition to accomplish accessing information anytime no matter the distance of user's location. This is not only related to largely distributed systems and applications, but about highly dynamic and mobile sets – clusters of participants, interacting with each other and storing data on mobile devices, as well as in remote facilities. PvC systems certainly come to facilitate CSCW making every kind of such systems to look as the simplest groupware option and providing a new and particular kind of such systems, what might be called as PvCE-SCW. This paper reports on current efforts on this type of systems describing their requirements and challenges with the intent to provide a summary of successful accomplishments on this matter.Eje: Ingeniería de SoftwareRed de Universidades con Carreras en Informática (RedUNCI

Towards a pervasive data mining engine: architecture overview

Current data mining engines are difficult to use, requiring optimizations by data mining experts in order to provide optimal results. To solve this problem a new concept was devised, by maintaining the functionality of current data mining tools and adding pervasive characteristics such as invisibility and ubiquity which focus on their users, providing better ease of use and usefulness, by providing autonomous and intelligent data mining processes. This article introduces an architecture to implement a data mining engine, composed by four major components: database; Middleware (control); Middleware (processing); and interface. These components are interlinked but provide independent scaling, allowing for a system that adapts to the user’s needs. A prototype has been developed in order to test the architecture. The results are very promising and showed their functionality and the need for further improvements.FCT -Fundação para a Ciência e a Tecnologia(PTDC/EEI-SII/1302/2012

Human-computer interaction in ubiquitous computing environments

Purpose &ndash; The purpose of this paper is to explore characteristics of human-computer interaction when the human body and its movements become input for interaction and interface control in pervasive computing settings. Design/methodology/approach &ndash; The paper quantifies the performance of human movement based on Fitt\u27s Law and discusses some of the human factors and technical considerations that arise in trying to use human body movements as an input medium. Findings &ndash; The paper finds that new interaction technologies utilising human movements may provide more flexible, naturalistic interfaces and support the ubiquitous or pervasive computing paradigm. Practical implications &ndash; In pervasive computing environments the challenge is to create intuitive and user-friendly interfaces. Application domains that may utilize human body movements as input are surveyed here and the paper addresses issues such as culture, privacy, security and ethics raised by movement of a user\u27s body-based interaction styles. Originality/value &ndash; The paper describes the utilization of human body movements as input for interaction and interface control in pervasive computing settings. <br /

A survey on location systems for ubiquitous computing

This thesis report is submitted in partial fulfillment of the requirements for the degree of Bachelor of Science in Computer Science and Engineering, 2007.Cataloged from PDF version of thesis report.Includes bibliographical references (page 36-39).Emerging ubiquitous computing applications must know where things are physically located. To meet this must, many different location systems and technologies have been developed. In this thesis, we discuss the basic techniques used for location detection, describe taxonomy of location system features, present a survey on research and commercial location systems, and finally, compare these location systems using the identified features. It is our hope that this paper is a useful reference for a newcomer to the area of location detection for understanding and evaluating the many options in this domain.Sheikh Iqbal AhamedMatin Saad Abdulla

Pervasive data mining engine

Dissertação de mestrado integrado em Engenharia e Gestão de Sistemas de InformaçãoAs ferramentas de Data Mining atuais necessitam de um conhecimento aprofundado na área para obter resultados otimizados. Esta dissertação apresenta como questão de investigação analisar “A viabilidade da construção de um sistema de Data Mining semiautónomo com características pervasive, sem perder a sua identidade e funcionalidades” e como objetivo desenvolver um protótipo de um sistema designado Pervasive Data Mining Engine que revolucione e facilite o processo de Data Mining. A metodologia de investigação utilizada é o Design Science Research. O Pervasive Computing oferece a possibilidade de serviços/aplicações estarem disponíveis em qualquer lugar, de forma invisível e não intrusiva ao utilizador. O protótipo desenvolvido apresenta benefícios como a realização automática de processos de Data Mining, a construção de modelos de Data Mining em paralelo, o registo de todas as instâncias do processo e a possibilidade de comparação entre elas. O Data Mining Engine é também capaz de se adaptar às necessidades dos utilizadores, com diversas possibilidades de configuração, resolvendo processos de Data Mining em modo automático ou manual, permitindo também um modo misto, em que é possível definir tarefa a tarefa o que é executado automaticamente ou manualmente pelo utilizador.

Mediaattori – Urban Mediator A hybrid infrastructure for neighborhoods

This design research project investigates the area of designing at the boundaries of digital and physical urban space. Its aim is to present cities with a direction for the future that addresses the possibilities presented by the interweaving of new digital technologies and urban space, for empowering people in shaping their own city. The approach followed is not technologically driven but rather takes people’s everyday practices (de Certeau 1984) as the grounding point for the investigation. The design process is built upon dialogues with people and the urban environment as a way of gaining understanding of urban everyday practices and designing in harmony with them. The resulting design concept, Urban Mediator, illustrates a local and people-centered perspective for our urban futures. It proposes a hybrid infrastructure for urban neighborhoods. This combined digital and physical framework gives people the possibility to engage in improving the quality of their everyday urban environments and their experience of these environments. The concept, presented through scenarios, is developed as a working tool for catalyzing discussion between different stakeholders that would be involved in a future proposal for collaborative design for cities. The thesis has been produced under the umbrella of the ARKI research group, at the Media Lab of the University of Art and Design
