Abstract
A touch panel for an interactive input system and interactive input system incorporating the touch panel is provided. The touch panel includes an optical waveguide layer and a resilient diffusion layer. The resilient diffusion layer is against the optical waveguide layer and causes light traveling within the optical waveguide layer to escape only when compressed against the optical waveguide layer at one or more touch points.
