ABSTRACT:
Disclosed herein is a tactile image drawing system for the visually impaired comprising: a) a computer for storing and processing graphic images and alphanumeric and braille text; b) a reference surface on which the graphic images or text will be drawn; c) a plotter connected to and cooperative with the computer for receiving data representative of the graphic images or alphanumeric text and for drawing the graphic images or alphanumeric and braille text, the plotter having an extrusion syringe for dispensing a bead of liquid material for drawing the graphic images or text on the reference surface; d) device connected to and cooperative with the computer and the plotter for governing the flow output and the temperature of the liquid material; wherein the liquid material is viscous and fast-drying and is adapted to dry as a raised relief when deposited on the reference surface, the raised shape creating a tactile representation recognizable by tactile perception performed by a visually impaired person.
