Abstract
A detecting portion outputs a contact state signal in accordance with a contact state with respect to an object to be manipulated. The contact state signal represents at least one of information of a sense of sliding of the detection portion with respect to the object and surface information such as surface roughness of the object. A signal processing section converts the contact state signal from the detecting portion into tactility information corresponding to at least one of the information of the sense of sliding and the surface information. A tactility providing portion is excited in accordance with the tactility information from the signal processing section to generate at least one of a traveling wave corresponding to the information of the sense of sliding and a standing wave corresponding to the surface information. A transmission portion transmits at least one of the traveling wave and the standing wave generated by the tactility providing portion to a finger of an operator.
