This paper discusses the challenges related to the insertion of Virtual and Augmented Reality in the teaching and learning processes, considering their multidisciplinary aspect, the adherence to Web 3.0 and a scenario of possible gains and results with such an insertion. There will be pointed out the features that made VR and AR solutions with a potential big impact, despite not properly explored...
In neuroimaging, magnetic resonance images can be used to locate and obtain various parameters in order to find a wide range of pathologies, improving diagnosis and hence early treatment. Since images of the brain are volumetric, they are treated volumetrically in voxels, rather than planarly in pixels. We present an alternative implementation of local neighborhood-based texture parameters that have...
3D virtual environments provide a large potential for the development of applications in several domains. Throughout the years different efforts have been done in order to enhance the development of these environments. In particular, the proposal of interaction metaphors applied to 3D environments which aim at replicating real world concepts into the virtual environment, facilitating user's interaction...
The wide spread of mobile devices on the today's market has put in the user's hands, high computing capabilities and a wide variety of sensors, including integrated devices digital cameras. This has enabled the rise of Augmented Reality, which seeks to superimpose digital information over the real world in order to enhance it for a particular purpose. This paper presents a state of the art on this...
The use of Virtual Environments in system control operation, in particular power systems (power generation and propagation), provides new paradigms to daily activities of monitoring and controlling. The existence of a three-dimensional geometric model, true to the real structures, when used to develop Virtual Reality systems, allows the acquisition of mental models that improve communication between...
The emerging of BIM (Building Information Modeling) techniques will change traditional procedures of design and maintenance for electric substations. In addition, Computational Holography, supported by wearable computers, has the potential to allow simultaneous engineering work, based on mixed reality and computer vision capabilities. It is believed that this set of tools will increase engineering...
This article presents the objectives of the project, Training of Trainers in Robotics for Schools in Vulnerable Areas of Costa Rica as well as the main activities, and the results that have been obtained in its first phase of execution. This is a joint project of the School of Informatics of the National University of Costa Rica (UNA), the Costa Rican Institute on Drugs (ICD) and the Ministry of Public...
