Haptic interfaces require mechanical components to transmit forces to an operator. However, if illusion can display sense of force to an operator, it is possible to develop a novel haptic interface without any mechanical components. In this paper, in order to develop such a interface, a pseudo-haptics resulting from only visual effects is studied. Fisrt, a user interface using visual tracking with a camera was developed to acquire the position of user's hand. A virtual coupling was used to provide the illusion. An experiment was conducted with the developed interface to evaluate the pseudo-haptics resulting from visual effects caused by the proposed method. In the experiment, ten subjects pushed the spring in virtual reality space with and without the virtual coupling. The experimental results indicated that all subjects tended to feel stronger pseudo-haptic sensations with the virtual coupling.
