TACTILE DIAGRAMS: What are tactile diagrams?
A Tactile diagrams are raised line drawings (similar to Braille) that can be used to transmit visual information, such as that found in graphs, chemical structures, and biological drawings. Tactile diagrams are created by using computer software files or a line drawings of images. Diagrams are transferred to tactile image paper and a thermal image enhancer burns the raised lines into the paper. Tactile drawings are typically used by individuals who are blind. Tactile diagrams can be accessed through a diagram library, or they can be created with the equipment just described. Your campus disability student services staff can help you procure tactile diagrams if a student needs them as an accommodation in your course. A good source for information on tactile diagrams and a tactile diagram library can be found at Purdue University at http://www.purdue.edu/odos/drc/tactilediagrammanual.php.
