---- PROTOTYPE --------- PURPOSE: To create a prototype of an inexpensive, portable Braille writing device with no electronic components for individuals who are blind or have low vision. Four mechanical engineering students at Johns Hopkins designed a portable low-cost Braille writing device that has no electronic components. To keep assembly and maintenance costs low, this hand-held writer operates in a purely mechanical fashion. It features six buttons that can be depressed to produce any of the embossed patterns that correspond to a Braille letter, number or punctuation mark. The device is used with a traditional Braille slate that features rows of rectangular openings (cells). When a piece of paper is inserted into the slate, the device can insert one Braille letter or number into each cell. Normally, a blind person uses a stylus to poke up to six indentations into each cell, forming one bump at a time. The students’ device uses metal pins to emboss up to six marks at once, which could accelerate the writing process. Because the buttons are close together, a single finger can depress more than one.
