Design of a transparent tactile stimulator

This paper presents the design of a transparent tactile stimulator, based on the friction reduction between the fingertip and the active surface. With such a design, the ratio between the useful area (i.e. the active display and the tactile area) and the device face is equal to 0.7, while the touched area's size is 93mm×65mm. Key design procedure is given, and experimental results are presented.
