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.
