Foursquare, the currently most popular location-based social network, allows users not only to share the places (venues) they visit but also post micro-reviews (tips) about their previous experiences at specific venues as well as "like" previously posted tips. The number of "likes" a tip receives ultimately reflects its popularity among users, providing(More)
Usage of mobile commercial communication devices is continually increasing. However, these devices require a fixed infrastructure and do not function in mobile ad-hoc networks (MANETs) characterized by large delays or disruptions. Furthermore, these devices do not support the emerging communications needed when the location of information publishers and(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)
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)
Applications requiring Content Centric Network (CCN) in delay-tolerant, peer-to-peer, multi-hop, and infrastructure-less environments are likely to increase as the use of mobile devices continues to rise and as the need to disseminate information without knowing the name or location of the destination grows. Currently, these capabilities are provided by CCN(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)
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)
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)
