Transparent tactile feeling device for touch-screen interface

We propose a transparent tactile feeling input device on the touch-screen interface, which provides actual keystroke and tactile key feeling without preventing the function of the touch-screen interface. Without using mechatronics elements such as force sensor or actuators, the device can adapt to the touch-screen interface used in general. In order to realize tactile feeling of clicking, we referred to a specific shape of the conventional switch in design process, and formed structure of the input device with the transparent silicone elastomer. Consequently, the experiment shows transparent haptic device realized click feeling on the touch-screen display.
