Abstract : Interaction through touch and manipulation is known as haptic interaction. We are working to develop advanced haptic technology that allows human users to touch, feel, grasp, and manipulate a set of special objects: objects located remotely, objects too small, too large, or too dangerous for normal human interaction, or objects that exist only in simulated worlds (virtual objects). We have built a baseline haptic system that includes a light, high bandwidth force feedback device that allows the user to touch and manipulate virtual objects in a simulated environment. We have created software that simulates the behavior of and interaction between virtual objects. We have designed efficient contact detection software for detecting the collision between simulated bodies or the collision between those bodies and the haptic interface. We have created haptic algorithms for mediating the force that the user feels when touching a virtual object. Using these components we have created a collection of working demonstrations to illustrate the functionality of an advanced haptic system. Finally, we have built prototype, integrated haptic demonstrations for aircraft maintenance training and a common surgical procedure known as an anastomosis.
