Tactile technology is not mainstream but it is indeed widely needed. Using the systematic patterns that different sound waves produce on material with small particles, can help in the development of tactile tablets. There are currently no effective, commercially available standalone devices that the visually impaired people can easily carry and interact with them via touching and hearing. Therefore, this project aims to fill this gap by designing a testbed for studying the principles of a sound driven flexible braille language display. Input from both processor and camera can be presented on a Cymatics plate. Input from camera requires image processing to extract elements from images. Results have showed great results for text extraction, however further work needs to be done on images that contain letters alone. First eight capital English alphabets are associated with specific patterns. With industrial fabrication of tiny vibrators and further work on the system, the first tactile tablet will be ready in market.
