Several fields of the knowledge have been benefited by technologies from Virtual Reality (VR) area. This paper presents an analysis of problems related to the domain of dentistry, specifically for training in anesthesia, and the possibility of resolution using VR. The analysis assumes that the haptic interaction in virtual environments is relevant in the area of training in health and may contribute in the skills acquisition, providing realistic experiences to the trainess. Initially, a detailed requirements survey with the participation of experts was conducted, as well as the development of a prototype for preliminary testing.

Learning processes currently are undergoing a major transition, given the different methods, techniques and paradigms applied in education. In this context, the use of information technologies as tools to support teaching can be characterized as one of the major advances of recent decades. This paper presents a summary of a research that seeks to integrate two distinct technologies (AVAs and Virtual World), through a known solution called Sloodle. Is demonstrate the use of such a solution on the educational area, presenting its operating cycle by developing a case study with activities involving the OSI model and networking protocols in a discipline of Computer Networks.

This paper presents the construction and the instrumentation of a virtual reality simulator for training operators of grain harvesters. Data entry is accomplished by using a custom interface with the same characteristics of the control panel of a real harvester. The simulator is mounted on a moving platform that reacts according to the Virtual Environment ground. Preliminary tests show the effectiveness of the method used for instrumentation and communication between the virtual environment and the interaction devices.

Many computational applications for virtual medical training manipulate 3D objects that represent organs and human tissues. These representations, in function of the training requirements, may include parameters such as shape, topology, color, volume, texture and, in certain cases, physical properties such as elasticity and stiffness. An approach is presented in this paper, combining methods and models that are efficient to simulate elastic deformation, obtaining equilibrium between visual and haptic realism. Based on this model, visual and/or haptic outputs are generated for users in order to provide to learner sensations close enough to those they would have if the training were provided with real objects. The results regarding deformation processing time are compatible with those required for haptic interaction and provide adequate visual feedback from using meshes composed of a large number of polygons.

This short paper proposes the development of three different applications for health education with the aid of Augmented Reality. Some figures of current development prototipes are also show and future works are proposed. We expect these applications will help extend health education to students' homes from all educational stages and expect to minimize some problems related to anatomy education in college, such as costs for obtaining corpses and lack of skilled professionals.

Technological advances have created new possibilities in education, requiring the development of new pedagogical practices that contribute to the process of teaching and learning. This paper presents a proposal for the construction of an immersive virtual laboratory of computer networks in 3D OpenSim environment. The main advantages of the proposal are the development and the treatment of issues related to context-aware computing, such as: cognitive styles, technology used, analysis of learning, expertise and quality of context. The prototype of this laboratory is currently in development, with some positive partial results.

In this work we present HapticBrush, a graphical application aimed at interactive digital painting of virtual screens using the Phantom haptic device, in which the artist has at his/her disposal a variety of brushes with different shapes, colors, sizes, spacings, and textures. The tests conducted show that the Phantom device reproduces tactile brush sensations on the canvas through the simulation of the pressure effect, by applying forces to the pen device. Thus, the experience of the artist's perception with respect to different types of brushes for the creation of digital art is evaluated. The results show that this experience is improved and the level of immersion of the user is increased, through the use of touch as a further means of interaction with the virtual world.

Virtual and Augmented Reality are used in the production of complex virtual environments, using non-trivial input and output devices to provide users with a sense of immersion in real-time synthetic worlds. Consequently, the design and development of such applications becomes complex where the software component reuse is not an option, but rather a necessity to enable development. In this paper we present an architectural model for a platform for the production, sharing and implementation of Virtual and Augmented Reality applications called NRVA. In this work we present the description of the main elements of the proposed architectural model and preliminary results of the research. The results point to the feasibility of the proposed model.
