Blind people require braille books to read. Unfortunately, translating a 500 page book into braille nearly doubles the thickness. Designer Seon-Keun Park, Byung-Min Woo, Sun-Hye Woo and Jin-Sun Park try to solve this problem by creating the Braille e-book concept. It adopts the EAP technology that can dynamically change the surface pattern by way of an electromagnetic signal to simulate braille text.
