The purpose of this paper was to "examine human visuo-motor behavior when visual and haptic feedback displays are integrated." The authors seek to improve haptic interfaces by providing guidelines and principles for designing haptic interfaces. The authors use a Fitt's Law paradigm to develop a framework for designing haptic interfaces. The experiment consisted of trying to move a cursor to a target on a display with a knob. The test was repeated using six different types of haptic feedback. Each subject completed 5 session that were spaced at least one day apart.

The authors found that the target damping condition resulted in the best overall performance and had a significant increase in performance over no haptic feedback. Target-marker and textured-target conditions resulted in decreased performance when compared to no haptic feedback. The authors conclude that damping forces over the target areas greatly improves performance in rapid aiming tasks.
