Surgical training systems based on virtual reality (VR) and simulation techniques for tissue deformation may represent a more cost-e!ective and e$cient alternative to traditional training methods. Additionally, VR is a technology that can teach surgeons new procedures and can determine their level of competence before they operate on patients. At(More)
We present a full featured surgery simulator for endoscopic third ventriculostomy (ETV) in an interactive grid environment. The basic ventriculostomy simulator introduced previously has been extended with new 3D models and animation methods for raising the simulation realism. It enables full haptic interaction with textured deformable models of a(More)

In order to understand the dependencies in the power system we try to derive state information by combining high-rate voltage time series captures at different locations together with data analysis at different scales. This may enable large-scale simulation and modeling of the grid. Data captured by our recently introduced Electrical Data Recorders (EDR)(More)
— This paper introduces a virtual arthroscopy training simulator as a beneficial tool for partial meniscectomy procedure. The modeling methods of virtual environment, haptic interface establishment, and the system integration are described in detail. With the combination of interactive visual and haptic feedback, the simulator is designed to aid surgeons in(More)
In the so-called rubber hand illusion, synchronous visuotactile stimulation of a visible rubber hand together with one's own hidden hand elicits ownership experiences for the artificial limb. Recently, advanced virtual reality setups were developed to induce a virtual hand illusion (VHI). Here, we present functional imaging data from a sample of 25 healthy(More)
