O aprimoramento de um software de estúdio virtual por meio de técnicas de matting digital e registro de objetos virtuais

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

A lousa digital interativa no ensino fundamental: um estudo de caso de uma escola municipal brasileira

The main objective of this paper is to realize a review of literature about use of Interactive Digital Whiteboard, as a tool for improving the quality of education. We intend to show some results already reported in several studies in this area, and thus contribute to the systematization of knowledge about this resource. We found that the positive impacts of digital interactive whiteboards are specific and depend on the model followed in its implementation. Although the literature on this technology still emerging, there is evidences of good practice and positive results in all areas of the curriculum. The outcome of this research shows that to get potential benefits of digital whiteboard will be necessary, at first, to understand the process implementation and appropriation. If hardware and software of Interactive Digital Whiteboard not available and adequately used all their potential benefits not will take effect.
