Tactility providing apparatus and manipulating device using the same
First Claim
1. A tactility providing apparatus comprising:
- detection means for outputting a contact state signal in accordance with a contact state with respect to an object to be manipulated, the contact state signal representing at least one of information of a sense of sliding of said detection means with respect to the object and surface information such as surface roughness of the object;
signal processing means for converting the contact state signal from said detection means into tactility information corresponding to at least one of the information of the sense of sliding and the surface information;
tactility providing means which is excited in accordance with the tactility information from said signal processing means 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; and
transmission means for transmitting at least one of the traveling wave and the standing wave generated by said tactility providing means to a finger of an operator,wherein while the finger of the operator is in a non-contact state with respect to the object, the information of the sense of sliding with respect to the object is provided to the finger, through the traveling wave transmitted from said transmission means, in accordance with the contact state signal from said detection means, and the surface information about the object is also provided to the finger through the standing wave.

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.
