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). The goal of this work is to develop the technological foundation of advanced haptic systems and to assemble that technology into a useful surgical simulator. In the first year of this effort we focused on developing the basic technology and methods needed to build interactive haptic applications. In this, the second year of effort, we have assembled these components into several prototype systems. We have built integrated systems for surgical anastomosis, heart palpation and aircraft maintenance. These systems were built upon a common software foundation that includes modules for virtual haptic interaction, physics-based simulation, and computer graphics. While these systems are not yet complete they demonstrate significant progress towards our goal of building virtual reality based training systems that are realistic, flexible, useful, and commercially viable.
