The support for 3D technologies in Digital Television (DTV) environments extends the possibilities of entertainment and interactivity. In this paper is described an architecture based on a middleware for Digital Television (DTV) that incorporates 3D technologies on Brazilian standard for DTV. The integration strategies will be presented and compared with(More)
The development of virtual reality (VR) systems can join several functionalities. Thus, the knowledge of specific techniques, as well as the learning of programming libraries of devices, and the integration of tasks demand time and can become complex the development process. The goal of this course is to present a set of libraries called CyberMed, set up to(More)
More intuitive modes and devices to interact in virtual reality environments have been subject of several researches. In this context, the inclusion of motion tracking to applications can improve user's experience. This paper presents the use of a magnetic tracker on education and integration of this device to a framework for developing educational and(More)

Haptics have been largely used in VR environments, especially in training systems in which user dexterity is a mandatory requirement to determine performance. Besides that, through tactile object exploration, applications can offer a high level of interaction to users. This work presents CybHaptics, a set of classes for the CyberMed, a system for fast(More)
This work presents a virtual reality based simulator, the SITEG, developed to allow the training of gynecologic exam. This system simulates the steps presented in a real gynecologic exam and uses visualization and haptic devices to provide a realistic training. The main features of the system are its development based on free software, its support to(More)
