Abstract : Physical description: 1 VHS video; 1/2 in.; col.; sd.; mono; 5 mins; standard playback sp. This project develops and demonstrates key technologies for advanced virtual interaction for surgical simulation and teleoperation systems used to perform remote surgical procedures. Our focus at MIT during the past year has been to develop the first level of interfaces and algorithms needed to accomplish the broad goals of performing virtual and remote surgical procedures. During the past year we have implemented a computational environment including control software, graphics software and computer hardware, to support the development of haptic rendering algorithms. We have demonstrated tweezer interaction with flat compliant surfaces to simulated grasping of tissue and developed a real-time, reduced order, finite-element simulation of compliant materials. The resulting systems has been used successfully to achieve the year-one goal of demonstrating multi-finger manipulation of virtual compliant material. In addition, we have performed preliminary investigation and design of a remote palpation and manipulation device which will be used in the coming years to perform real surgical procedures
