“Virtual Studio” is a system developed for the creation of virtual sets, as well as any threedimensional virtual objects that can be digitally integrated to the scenes captured on a real television studio. Through techniques such as chroma-key, computer graphics , augmented reality and virtual reality is possible flexibility in producing content for digital TV, reduce cost and meet 12.485/2011 law, the Brazilian “Law of Pay TV”, which has among its objectives “to increase the production and circulation of diverse and quality Brazilian audiovisual content, generating jobs, income, royalties, professionalism and strengthening of national culture” (ANCINE , Brazilian Nacional Cinema Agency ). Based on this background, an overview of the benefits of using the technologies mentioned for the production of content for digital television is presented. This work involves the development of a system of Interactive Virtual Studio called ARSTUDIO per team of researchers from the Posgraduate Program in Digital Television: Information and Knowledge at UNESP, São Paulo State University in Bauru, State of São Paulo, Brazil.

Post-Occupancy Evaluation of buildings considers user satisfaction, building pathologies and performance, as well as users interventions in the built environment. The possibility of identifying interventions regardless of the user could provide a significant gain in the efficiency of Post-Occupancy Evaluations. We foresee the application of Augmented Reality (AR) to improve the identification of renovations by overlapping the construction information model with an image of the actual building. This article validates the use of AR on existing smartphone and tablet applications. This study proposes the incorporation of AR into the planning, execution and application of Post-Occupancy Evaluation. For the planning, this study proposes the development of a new research tool. With regards to the execution, this study examined the data collection conditions on site through the visualization of overlapping models. For the application, this study proposes displaying the results through the use of RA information layers. The transparency oft he RA model was used to allow comparison between the virtual model and the real model. The development and adaptation of the virtual model and the solution developed for the experiment of the RA proposal are presented and discussed. The experiment points to shortcomings that still make the proposed technological solution unfeasible.

A utilização da Web como plataforma para a educação a distância (e-learning), tem sido uma das grandes alternativas para a educação em sala de aula tradicional. Embora esses sistemas sejam amplamente utilizados, existem limitações quanto à dificuldade de busca, integração e reuso dos materiais existentes. Neste contexto, neste trabalho é apresentada uma arquitetura multiagente para o desenvolvimento de sistemas Web semânticos para a gestão de conteúdos educacionais – SWSGC, onde de acordo com os requisitos do usuário são propostos os conteúdos educacionais (OAs) do curso. Tais conteúdos são recuperados de repositórios heterogêneos de OAs, anotados mediante padrões de metadados educacionais e ontologias de domínio. Esta arquitetura proposta visa automatizar atividades relacionadas à gestão de OAs tais como: a autoria de OAs, a autoria de curso, e a busca e a anotação semântica de OAs.

The project presents an explanation of the technique of video mapping, resource use, origin and use of the strands. Also conducts multidisciplinary literature review of concepts that can be applied to the technique of video mapping: Augmented Reality, Spatiality in Virtual and Real Environments. The project also introduces aspects of the history of cinema and audiovisual narrative. In addition conducts an inventory of software and hardware required for the technique of video mapping, reports performing experiments with the use of the technique and discusses the results obtained. As a contribution to development area, proposes to use video mapping as an augmented reality tool at an immersive experimental film language

A virtual studio system can use technologies as augmented reality and digital matting to decrease production costs at the same time it provides the same resources of a conventional studio. With this, it’s possible for the current studios, with low cost and using conventional devices, to create productions with greater image quality and effects. Some difficulties are recurrent in virtual studio applications that use augmented reality and digital matting. The virtual objects registration in augmented reality techniques suffer from problems caused by optical distortions in the camera, errors in the marker tracking system, lack of calibration on the equipments or on the environment (lighting, for example), or even by delays in the virtual objects display. On the other hand, the digital matting’s main problem is the real-time execution to preview the scene, which must have optimized processing speed at the same time while maintain the best image quality possible. Taking the given context into consideration, this work aims to give continuity to a virtual studio system called ARStudio, by enhancing digital matting, virtual objects registration and introducing a segmentation based on depth map, yet adding better control over functionalities previously implemented
