Bone marrow transplant is a relatively new procedure to treat recently considered incurable diseases. One important part of the procedure is the process of harvesting the donor bone marrow. We are developing a virtual reality simulator for bone marrow harvest that integrates interactive stereo visualization and force feedback techniques. The main objective(More)
 Virtual Reality (VR) systems allows the design of interactive and immersive environments for the simulation of a wide range of situations. These features has been exploited to build realistic applications in order to provide study and training in several areas, particularly in medicine. In this sense, the addition of techniques to assess the actions of(More)

Virtual reality-based training simulators, with collaborative capabilities, are known to improve the way users interact with one another while learning or improving skills on a given medical procedure. Performance evaluation of Collaborative Haptic Virtual Environments (CHVE) allows us to understand how such systems can work in the Internet, as well as the(More)
Several approaches to perform assessment in training simulators based on virtual reality have been proposed. There are two kinds of assessment methods: offline and online. The main requirements related to online training assessment methodologies applied to virtual reality systems are the low computational complexity and the high accuracy. In the literature(More)
