Virtual Cochlear Implant Insertion For Medical Education, C. Todd, F. Naghdy Oct 2011

Virtual Cochlear Implant Insertion For Medical Education, C. Todd, F. Naghdy

Professor Fazel Naghdy

A surgical simulator has been developed for the purpose of training otologists in cochlear implantation. The simulation provides real-time visual and haptic feedback during implant insertion into the human Scala Tympani (ST). The benefits and possible outcomes for this type of simulator are presented. Methods for model generation are discussed, for anatomical and prosthetic structures used in the simulation. Development of the interactive model with force-feedback is presented, with results.


Skill Acquisition In Transfer Of Manipulation Skills From Human To Machine Through A Haptic Virtual Environment, Y. Chen, F. Naghdy Oct 2011

Skill Acquisition In Transfer Of Manipulation Skills From Human To Machine Through A Haptic Virtual Environment, Y. Chen, F. Naghdy

Professor Fazel Naghdy

A new paradigm for programming a robotics manipulator is developed. It is intended that the teaching of the machine will begin with the necessary skills being demonstrated by the human operator in a virtual environment with tactile sensing (haptics). Position and contact force and torque data generated in the virtual environment combined with a priori knowledge about the task is used to identify and learn the skills in the newly demonstrated tasks and then to reproduce them in the robotics system. The peg-in-hole insertion problem is used as a case study. The overall concept is described. The methodologies developed to …
