In this study, we propose a novel communication device for intimate users. We focus on kisses, since kisses are haptic communications that can express deep emotion. We considered that if we mutually present the haptic sensation to each mouth, we can convey the expression of emotion, deepen their relationship. We made a first prototype using water-balloons, and a second prototype using bended rods. We also conducted an experiment to evaluate the effect of the device to the relationship between users, by measuring frequencies of eye-contact and smiles, and confirmed the effectiveness of our device.
