A dual purpose touch and braille touch screen device is disclosed that allows both sighted and visually impaired people to use the same touch screen. The creation of a dual purpose touch screen that can be used by both sighted and visually impaired people will increase the accessibility of touch screen technology to a larger audience. To accommodate both audiences, the touch screen would be made up of hundreds of thousands tiny, flexible, smooth glass rods (think of the material used to make fiber optic cable) that can operate independently of one another. The rods can be manipulated by the touch screen to dynamically raise and lower creating the Braille characters. Because the rod material can also conduct light, images such as English alphabet text or color graphics can be displayed over the Braille characters. This touch screen would present the image of a solid surface to sighted individuals, but Braille characters could be read by the visually impaired. 1 2
