Recently, several researches of haptic devices have been conducted. Haptic devices provide users with sense of touching virtual objects such as Computer Graphics (CG) by force feedback. Since they provide force feedback from a single point on an object surface where users touched, users touch it by point contact. However, they cannot provide a sense such as humans touching an object with a finger pad because humans do not touch by point contact but surface contact. We focused on this characteristic and developed surface contact haptic device. To touch a CG object in surface contact, we use a plane interface. It provides force feedback to the normal direction by being approximated to tangent plane on a CG object surface where users touched and the sense of grabbing it. In the evaluation experiments, twelve users evaluated this haptic device. From results, we see that users could feel sense of touching in surface contact and grabbing a CG object.
