From 2000, Dai Nippon Printing (DNP) has been practicing universal package design and has made progress in developing designs for visually impaired people, especially in the realm of paper packaging. "Barcode-Talker" is an application designed for visually impaired people: it allows users to listen to a product's information read out by an audio-assistant when a barcode is read through the user's smartphone. DNP has developed the "barcode sign," an embossed L-shaped barcode, which enables visually impaired users to locate the barcode by touch, and strives to promote universal design-oriented packaging.
