  • Patent number: 9460634
    Abstract: Systems and methods of digitally recording and reproducing tactile drawings are disclosed. The method includes moving a stylus over a path on the first tactile drawing medium to form a tactile feature thereon, and digitally recording the path of the moving stylus to generate digital path data. The method also include reproducing the tactile feature on a second tactile drawing medium operably disposed in a tactile printer based on the digital path data. The systems and methods include forming tactile drawings based on a digital graphics file, including filtering the digital graphics file to form a .RLD file suitable for forming a tactile drawing having features capable of being tactilely sensed.

  • Patent number: 9403401
    Abstract: A thermal eraser for erasing tactile drawing features from a tactile drawing medium, along with methods of erasing tactile drawing features formed on a tactile drawing medium, are disclosed. The thermal eraser has a heated tip that can be heated to a temperature sufficient to cause the tactile drawing feature to flow back into the surface of the tactile drawing medium. The heated tip has a tip temperature that can be controlled by a temperature-regulating circuit. A set-point temperature can be used to set the tip temperature and maintain the tip temperature. The thermal eraser can be controlled by hand or by an electro-mechanical device such as a tactile printer.
