These images were created using Pro-Engineer Wildfire. The CAD drawings, complete with side views, were used to machine the system case by melting, bending, gluing, cutting and drilling white acrylic plastics. Red, green and blue acrylic plastics were cut and rounded in order to function as buttons, distinguishable from one another to facilitate ease-of-use. The Braille in the final prototype is not viewable on the face of each button on the provided drawings below.
