  • Interactive tactile display for computer screen
    Patent number: 6636202
    Abstract: Apparatus for converting a visual image into a tactile image. The apparatus comprises imaging means for converting incident light from the visual image into electrical signals that are proportional to the gray scale intensity of the incident light. The apparatus also comprises a tactile display device having a two-dimensional array of variable height pixels, wherein the height of each pixel in the tactile display is dynamically variable in proportion to the electrical signals from the imaging means. Preferably, the height of each pixel is inversely proportional to the gray scale intensity of the incident light so that the maximum height of a pixel occurs when a corresponding pixel in the visual image is black.
    Type: Grant
