Abstract: Virtual reality based surgical training is an emerging area of research interests. We have developed iDental, a simulator with haptic-visual-audio feedback for dental skill training. The simulator aims to train dental students in their early stage of learning to acquire basic operational skills. Based on our unique haptic rendering methods, iDental achieved some important features, including 6 degree-of-freedom haptic feedback, deformable object simulation, bi-manual coordination, and the simulation of fine manipulation in a narrow oral cavity. In this talk, I will briefly introduce the functions and the features of iDental, discuss challenging problems in haptic rendering, present preliminary user evaluation results and highlight some future research and development topics.
Biography: Yuru Zhang is a professor in the School of Mechanical Engineering and Automation at Beihang University in Beijing where she served as the associate dean of the school, the associate director of Robotics Institute. Currently she is the associate director of the State Key Laboratory of Virtual Reality Technology and System. Her primary research interest is haptic human-machine interaction including haptic user interface, teletraining and neurohaptics. She has published over 150 technical papers and holds 22 issued patents. She co-authored two books including "Robotic Dexterous Hands" funded by the National Science Foundation of China, and "Haptic Rendering for Simulation of Fine Manipulation" published by Springer. Professor Zhang is a senior member of IEEE and a member of ASME. She is on the Advisory Board for Teaching, the Ministry of Education, China. She was awarded the Outstanding Professional for the 21 Century by the Ministry of Education and the Excellent Investigator Award by the formal Ministry of Aeronautics Industry in China.
