Often, to distinguish between different objects, a human operator needs to feel the stiffness of each object. This haptic information is essential for performing delicate tasks in virtual reality or teleoperation environments such as robotic telesurgury. A high bandwidth, high dynamic range real-time haptic stiffness display was designed to explore a human's perception of stiffness. Also, controlling the stiffness of a haptic display device, as opposed to the reaction force, allows for stable high bandwidth haptic interaction.
