| Descripción |
Virtual Reality (VR) and associated technologies are experiencing growing importance in medicine and surgery. VR demands fast and real time simulations. Finite element analysis can be used for cutting simulation; however, finite element analysis is computationally intensive and is unsuitable for real time applications involving cutting of a large amount of tissue. We have developed a fuzzy logic based system which involves significantly reduced computational times and provides real time simulations of cutting. The user-exerted forces on a simulated cutting tool held by the user are dynamically measured and fed to the fuzzy logic system. The user-exerted forces and the stiffness of the element are first fuzzified and fed to a fuzzy rule base to provide the output membership values. These output membership values are then defuzzified using the centroid defuzzification technique to provide a crisp output of the cutting depth. The technique has been implemented in real time. Experiments with human users have shown consistent results.
