Patent number: 9786202Abstract: A surgical training system and method. The system comprises means for recording reference data representing a reference manipulation of a computer generated model of an object by a master user; means for physically guiding a trainee user based on the recorded reference data during a training manipulation of the model of the object by the trainee user; and means for recording assessment data representing an assessment manipulation of the model of the object by the trainee user without guidance.Type: GrantFiled: March 4, 2011Date of Patent: October 10, 2017Assignees: Agency for Science, Technology and Research, National University Hospital (S) Pte Ltd., National University of SingaporeInventors: Weimin Huang, Jiang Liu, Jiayin Zhou, Jing Zhang, Beng Hai Lee, Wing Kee Wong, Ngan Meng Tan, Zhuo Zhang, Fengshou Yin, Stephen Chang, Chee Kong Chui, Yi Su
