The forces of contact between the blade of the scissors and the plate are expressed by a nonlinear function of deflection at the crack front multiplied by the length of the contact region between the blade and the plate. The cutting model captures the combined effect of multiple fracture modes. The level of deflection that causes fracture is obtained using an energy approach. The cutting model predicts that, during fracture, force and torque responses of the scissors depend on the toughness and geometry of the plate, but do not depend on the stiffness of the plate. The model is used for haptic synthesis of interaction between a pair of scissors and a virtual plate. An implementation of the model is presented for the case of surgical scissors in contact with skin. The simulation results are compared to previous experimental data, demonstrating the realism of the cutting model behavior. This haptic rendering technique is computationally efficient and can be applied to real-time simulation.","PeriodicalId":117050,"journal":{"name":"First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems.

Khatib","doi":"10.1109/WHC.2005.118","DOIUrl":"https://doi.org/10.1109/WHC.2005.118","url":null,"abstract":"Exploring large virtual environments using a small haptic device with limited-workspace capabilities is a challenging task because the user very quickly reaches the borders of the physical workspace of the device. In the case of a computer mouse, this problem is solved by lifting the device off the table and repositioning it at a different location. With most ground-based haptic devices such indexing procedure is not possible and requires the use of an additional switch to decouple the device from the cursor and allow the user to relocate the end-effector at the center of the physical workspace. Below certain physical workspace dimensions such indexing methods become cumbersome to the operator and therefore different control paradigms are required. This paper presents a new approach referred to as workspace drift control which progressively relocates the physical workspace of the device mapped inside the virtual environment towards the area of interest of the operator without disturbing his or her perception of the environment. This technique uses the fact that people are greatly influenced by what they perceive visually and often do not notice small deviations of their hand unless that small deviation has a corresponding visual component.","PeriodicalId":117050,"journal":{"name":"First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems.
