Haptic technology is based on the sense of touch. It provides a new communication method that closely resembles the subtle, non-visual, and nonauditory communication methods found among biological beings. The mechanical interface device providing stimulus information such as tactile sensation and kinesthetic force to a user is called a haptic device or haptic interface. Goertz developed the „rst force feedback system during the 1940s for a master-slave manipulator designed to handle radioactive substances. Interfaces with the human sense of touch have actively been researched lately in various application „elds such as automotive and robotic to achieve great realism and interactivity including good accuracy and high performance [1, 2]. In the automotive „eld in particular, much attention is being placed upon the areas of driving performance, safety, driver comfort, and convenience. Haptic technology holds the key to enhancing capabilities in these areas.
