Polymer Braille is an E-Reader for the Visually Impaired

Current Braille e-readers have only a single line of characters and are clunky as well as expensive. Polymer Braille grew out of a North Carolina State University research project and aims to build a working tablet-style device with a screen made up of essentially an array of Braille dots which can display roughly a full page of information at a time and then change its contents like any other screen. The team has worked on shrinking the mechanics necessary for each of the clusters of raised dots with the right height and tactile feel.
