ABSTRACT: The purpose of this project is to explore different possibilities to produce tactile pictures that are comprehensible by the visually impaired. As a part of the thesis, different methods including micro actuator arrays which produce virtual 3D tactile displays, braille board with movable dots pins which is capable of producing refreshable braille, and techniques like thermoform, swell paper and silk screen which are capable of producing tactile pictures are studied. Bearing in mind factors like time, effort, cost and reusability, a 3D printer seems to handle the problem more efficiently compared to the above mentioned approaches. The 3D printer is therefore chosen to produce tactile pictures according to a set of example use cases. The use cases are modeled in software and viewed as stereolithographic (.stl) files. The .stl files are fed as input to the printer and the obtained results will be tactile in nature as well as accurate up to 100 microns, which complies with Americans with Disabilities Act standards. As a whole, we explored different user interfaces for the visually impaired and came out with a cost-effective solution/user-interface which can produce a 3D version of a 2D picture using recyclable plastic. This method can be used to produce “pictures” for the visually impaired. It can also be used, in future work, for training visually impaired individuals to understand 2D images on a touchscreen.
