Integration of Tactile Information and Visual Information Using A Glass Substrate Surface Acoustic Wave Tactile Display

This paper describes a new method to excite and propagate surface acoustic wave on a non-piezoelectric material surface. The method contains a combination of a LiNbO3 piece and a glass substrate. Successful work of an active type SAW tactile display using the glass transducer is reported. Additionally, installation of the glass transducer on an LCD to indicate tactile sensation with visual information and its demonstration are described.
