This paper deals with a tactile interface using force sensors. Touch panel, which uses contact position information for input, is spreading as a good candidate of intuitive man-machine interfaces. In addition to contact position information, using contact force information realizes intuitive and versatile input. “Haptic Desk” is a desk-type tactile interface that force sensors are attached to the legs of the desk. This technology can estimate contact force and contact position on the desk. Moreover, this technology can convert not only a desk but also other products, such as consumer electronics and furniture, into tactile interface. However, if the products are vibrated, the errors of the estimated external force and contact point occur. Because the inertia force of the product is not considered, the errors occur. For reduction of the errors, this paper expands the method of Haptic Desk by using an acceleration sensor. The usefulness of the proposed method is shown by experiments.
