A touch indication device comprises a light guide structure for passing light of a light source via total internal reflection. A touch surface disturbs the total internal reflection when touched, causing light to leave the light guide structure. A light enhancement layer converts the light leaving the light guide and sends the converted light to a light detector. The light enhancement layer amplifies the intensity and/or changes the color of the light leaving the light guide. The detector determines the position of the touch on the touch surface based on the light from the light enhancement layer.
