March 18 (UPI) -- Google is celebrating Japanese inventor Seiichi Miyake, who created tactile blocks to help the visually impaired, with a new Doodle.
Miyake used his own money to craft the tactile blocks in 1965 in order to help out a friend. The tactile blocks, previously known as Tenji blocks, help the visually impaired around the world navigate public spaces, crosswalks and railway platforms by using dots and bars that are placed on the street.
