This paper presents a technique for the construction of an elastic touch panel using silicone rubber. The technique is similar to that of the frustrated total internal reflection-based method for multi-touch sensing, but the surface of the touch panel is made of transparent silicone rubber rather than acrylic. Moreover, we embedded infrared LEDs within the rubber for multi-touch sensing. In tests, our touch panel had better sensitivity than one made of acrylic. Furthermore, unlike acrylic panels, it readily detects contact by styluses and other stiff objects. We implemented a touch panel based on our technique and tested it through experiments.
