Polymer Braille

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.

Polymer Braille is creating an interactive and refresh-able Braille display
technology to connect 315 million visually impaired individuals to the
digital world. The technology will fluidly display digital Braille books,
STEM related charts and graphs, and assist in navigating computers.
