In this paper, we propose a novel wearable haptic device to present contact sensations. Our goal is realization of a small ultra lightweight haptic device that enables mixed reality applications where people can move freely and two or more persons can simultaneously use. At first we clarify specification of a device weight and best way to present force to cutaneous sensation on the finger tip with an actuator. Then we propose a novel device which employs cutaneous sensation stimulation method utilizing wires that enables presentation of strong contact sensations by weak force. Therefore, we can make a small lightweight device (1.4g) by a small actuator. Moreover, since a response of an actuator also improves, quality force sense presentation is achieved. And the device can overlay the sense of force without barring ordinary manipulation of real objects or other users. Finally we present effectiveness of the device through experimental results.
