Recently, several researches of haptic devices have been conducted. Haptic devices provide users with a 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. I 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, ten users evaluated this haptic device. From results, we see that users could feel a non-rigid object by surface contact.
