    Page(s): 1 - 4
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (334 KB)  

    This work presents an architecture that supports collaborative semantic annotation for audiovisual (AV) contents on the web. The main goal is to propose a semantically oriented infrastructure to organize audiovisual material produced by Brazilian points of culture and independent producers so as to optimize the searches made by community TV broadcasters, schools, film societies and internauts. The collaboration will rely on a content annotation scheme, designed to stimulate both consumers and producers to enrich the overall content description by incorporating viewpoints and meanings associated to relevant scenes, regions and objects present in the production. The proposed architecture is based on technologies for AV content description, such as MPEG-7, semantic web concepts and the Ontology Web Language (OWL). This work considers that collaborative approaches, along with the on-going efforts in expanding the coverage of Internet broadband access in Brazil, will foster the dissemination of the digital technologies in the production and recording of cultural manifestations, allowing artists and entities to publish and distribute in a more effective way their cultural patrimony over the Internet.

    This paper describes an ongoing project of a collaborative tool for maintaining prices of goods. Unlike most online search tools, which have an agreement with sellers to list their products, the proposed tool will provide greater flexibility and reliability through collaborative updates. This proposal is supposed to offer different kinds of access to the system, such as PCs through the web and mobile devices. So, we hope to provide to consumers a more trustful system for collecting and maintaining prices. View full abstract»

  • Support for Collaboration in Wikis using Graphical Modeling to Achieve Improvements in Information Architecture and Accessibility

    Page(s): 12 - 15
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (278 KB)  

    Wiki is a collaborative tool for designing web communications allowing users to edit, add or revise content through a web browser. Despite of various benefits offered by the wikis use, there is no guarantee of a good structure of its content. This occurs especially by the difficulty to graphically visualize the information architecture. In this paper is proposed a Model-Driven Development (MDD) approach that supports creating graphical models of namespaces to generate wikis and facilitates the collaboration organization. Finally, the approach also aims to include accessibility features on models from official W3C guidelines such as WCAG and ATAG, allowing the wiki access by a wider range of user's types.

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (498 KB)  

    Robot arm simulators are systems that raise a lot of interest and motivation from students but safeguard their physical integrity as well as the equipments'. Telerobotics represents the control/operation of a robot arm from a distance while it performs highly risky manipulations (either with radioactive, explosive or other dangerous objects), for instance. For some telerobotic tasks, two or more operators need to work together depending on the complexity of the task or the complexity of the object being manipulated. A collaborative telerobotic simulator should offer an environment for executing robotic tasks that are divided in such a way that require operators mutual understanding and complementary work. This paper presents a telerobotic 3D simulator for collaborative robotic tasks, called CollBot4us (that comes from “COLLaborative roBOT FOR US”), which allows each operator to visualize the same 3D environment but from their own perspective and operating from different places (connected via network). CollBot4us is intended to be used for telerobotic tasks training as well as for collaboration strategies development. View full abstract»

    Collaborative Group Decisions Supporting Systems, Meetingware or Electronic Brainstorm represent a major challenge by the technological point of view just because they face the tough barrier of paradigm shift. Although already there are approaches such as IBIS or Quest Map to face this problem of collaborative group decision-making, few softwares are actually distributed or used for this purpose. Using a mixed ruse, based both on the IBIS model and the Quest Map system, a new solution to address the clash of resistance to this paradigm shift has been created. The aim of this paper is to present this new tool built. View full abstract»

    Hearing impairment was indicated as the second largest proven deficiency in brazilian population. People with such disabilities face many obstacles in their communication and interaction with listeners, even with equal opportunities for cognitive development. However, collaborative tools offer the possibility to improve the interaction between listeners and deaf. This work presents a case study conducted with listeners and hearing impaired in a collaboratively text production, using GoogleDocs® tools. Analysis of the results obtained in the case study show that the collaborative writing enhanced the interaction and contributes to a more harmonious and real coexistence among listeners and hearing impaired.

    This paper presents the initial results of an ongoing research project entitled engageGrid - Designing and Prototyping a Network of Commitments on the Grid Environment. The main goal of this project is to design and to prototype a commitment network as both a conceptual framework and a compound of computational artifacts capable of supporting knowledge workers - connected under certain criteria - on safely engaging in group work, by taking into account past accomplished commitments, as well as by identifying incoming possibilities from the network dynamics. The solution adopted was based on the assumption that effective management of (computer-aided) commitments in a network demands support of the life cycle of each engagement. This cycle was developed during the project, including the phases of configuration, negotiation, implementation, analysis and synthesis. View full abstract»

    We explore an user-oriented system implementation based on usability, inteligibility and efficiency aspects for literally and digitally illiterate and semi-literate users. An initial prototype was implemented using Hypothetical User Design Scenarios and its quality was informally evaluated by a little and valid group of users. Next, additional requisites were defined into a second prototype by using only one development iteration. The results seem adequate for this kind of people, but the work points out the importance of next iterations based on interactive design approach to better understand the user needs and it requires more work to significant improvements on software quality for illiterate users.

    This paper describes the process of developing an application called Social Proxy, including specification, implementation and programming model. Social Proxy is a minimalist view of the presence and activities of participants in online interactions[2]. The application was developed to support collaborative meetings in Second Life, 3D collaborative virtual environment chosen as the setting for this work. Our Social Proxy is called SP HUD, a component that provides a third person view allowing a clearer view of the group's activities. Thus, we are able to see all the avatars present in the shared space and know the interaction forms of each participant. Social Proxy is a component that is part of a larger project and this paper we present the activities performed, the challenges encountered and preliminary results. View full abstract»
